1.3 Quick Start

This section provides instructions for users who wish to experiment immediately with the evaluation kit. A fuller description of the kit and its use appears later in this document.

1.3.1 Setting-Up

This evaluation kit comprises a single board containing a socket for a 40-pin DIL PIC (or compatible) general-purpose µC, which the user may re-program with his applications software. THE EV6000 COMES WITH A PRE-CONFIGURED PIC 16C74AJW OR EQUIVALENT, CONTAINING DIAGNOSTIC FIRMWARE AND APPLICATION SPECIFIC DEMONSTRATION FIRMWARE FOR THE EV6020 AND EV6040 EVALUATION KITS. THE EV6000 IS SET FOR OPERATION AT 5.0V. The kit also contains two 20-way flat cables (one of which is needed for connection to an EV6020 or EV6040 CML Evaluation Kit) and a 9-way D-type RS232 cable (for connection to a PC), as shown in the Block Diagram of Figure 1. No board adjustments are required by the user. BEFORE APPLYING POWER, PLEASE CHECK THE FOLLOWING: ENSURE THE PIC µµC IS PLUGGED INTO SOCKET U2 ON THE EV6000 BOARD. CONNECT THE 9-WAY RS232 CABLE BETWEEN SOCKET J3 AND THE SERIAL PORT OF A PC. FOR USE WITH EV6020 OR EV6040 EVALUATION KITS, CONNECT A 20-WAY FLAT CABLE BETWEEN SOCKETS J1 ON THE EV6000 AND EV6020 OR EV6040 BOARDS. The EV6000 board has connections for a single 8 - 35V dc power supply. Only one board (as shown in Figure 1) needs to be connected as power is supplied to the other board over the flat cable. Each board has its own power supply regulator chip, with a jumper to select 3.3V or 5.0V (default) operation. MAKE SURE BOTH BOARDS HAVE THIS JUMPER SET TO THE SAME VOLTAGE. DAMAGE MAY RESULT IF THIS STEP IS NOT OBSERVED. DO NOT OPERATE EITHER BOARD WITH ITS VOLTAGE SELECTION JUMPER REMOVED. Ensure that the component value jumpers on the EV6020 or EV6040 evaluation board are correctly set Connect any other equipment as shown in Figure 1. Ensure the PC terminal emulator program is set up as detailed in section 1.2.1.2.

1.3.2 Operation

The EV6000 kit is designed to control the operation of an EV6020 or EV6040 Evaluation Kit. The firmware which is pre-configured into the PIC µC has both diagnostic and application specific The PICPROGA.EXE program can be used to re-program the PIC µC firmware, if required.

1.6 Detailed Description

1.6.1 Hardware Description

1.6.1.1 Operating Voltage

The selection of operating voltage (VDD = 3.3V or 5.0V) by jumper JP1 affects the choice of component values around the evaluation device on the EV6020 or EV6040 Evaluation Kit. Care should be taken to ensure that JP1 is set the same way as jumpers JP1, JP3, JP4, JP5, JP6 and JP7 on the EV6020 or EV6040 Evaluation Kit.

1.6.1.2 Clock/Oscillator

A 4MHz xtal is the highest frequency xtal that may be used with a PIC16LC74(A)JW at VDD = 3.3V. The PIC 16C74(A)JW has a similar limitation and is fitted for availability reasons. Although rated at 5.0V, it has been found to work successfully at 3.3V. Two jumpers JP2, which are normally fitted, select an on-board 4MHz xtal. An external 3.58MHz clock, for example, may be supplied to JP2_1 (1) once the jumpers have been removed, taking care to adjust any firmware timing routines accordingly.

1.6.1.3 RS232 Interface

The RS232 interface (connector J3) has its communications protocol determined by the µC firmware. A suggested configuration is 8 data bits, no parity, 1 stop bit and 19,200 baud with hardware handshake but without CR -> CR/LF conversion. Linefeeds are provided by the EV6000 firmware. The firmware supplied in the PIC µC assumes this configuration. 1.6.1.4Programming Mode TO ENTER PROGRAMMING MODE (a) Remove power from board (b) Disconnect the EV6000 from other Evaluation Kits (c) Ensure jumper JP1 is fitted in position 2,3 for VDD = 5.0V (d) Remove link on jumper JP3 (e) Insert links on jumpers JP4, JP5, JP6 and JP7 (f) Re-apply power to board (g) Connect the programming voltage (VPP = 12.5V to 13.5V) power supply between test point TP5 (+ve) and VSS (-ve) (h) Ensure the PIC µC programming utility PICPROGA.EXE is loaded into the PC under DOS and the PC is connected to the evaluation kit (i) Download firmware into the PIC µC and verify it TO LEAVE PROGRAMMING MODE (a) Remove power from board (including the programming voltage) (b) Remove links on jumpers JP4, JP5, JP6 and JP7 (c) Insert a link on jumper JP3 (d) Reconnect jumper JP1 in its original position (e) Reconnect the EV6000 to the other Evaluation Kits, checking that the voltage selection jumpers are correctly set (f) Ensure the terminal emulator program is running on the PC (g) Re-apply power to board and run µC firmware via the PC terminal emulator

1.6.2 Software Description

1.6.2.1PIC µC Programming Software This is supplied on disk as a self-documented executable file PICPROGA.EXE for a PC running DOS (either directly or as a DOS window in Windows 3.11 or '95). It is not recommended for use on Windows NT systems. Please note that this programming software does not meet the Arizona Microchip Technology verification requirements for a "production quality" programmer. Also, it does not support the programming of ID locations and there is no checksum facility. The user interface consists of two windows. The top window contains the operating instructions and the bottom window shows the command line and data communications with the PIC µC. When the top window first appears the user will be prompted to enter the number of the serial communications port to which the EV6000 board is connected. Once the user has entered this number, the following commands are displayed: pressF to load file. pressC to enter Configuration Word. Currently - xxxx pressB to check target device is blank. pressP to program target device. pressV to verify target device. pressR to read target device. pressA to view contents of program data array. pressEscto return to DOS. A new function from the above table can be selected whenever the >ok prompt appears in the bottom window. Notes: a) Assembler output files must be in the Intel hex format (.HEX) in order to be usable by this programming software. b) The PIC µC supplied has a Configuration Word which is preset to 3FB9H if it is a PIC 16C74JW or 16LC74JW, or to 3FB1H if it is a PIC 16C74AJW or 16LC74AJW. In each case, this selects the crystal oscillator, disables the watch dog timer, enables the power up timer and disables code protection. The programming software currently defaults to 3FB1H. Consult Arizona Microchip Technology for more information on the Configuration Word. c) The "blank check" command (B) only looks at the first location. A programmed device will always have data in this location as it is the program start address. d) For each of the commands B,P,R and V the user will be prompted to manually reset the target µ C, by pressing the RESET switch (SW1) on the EV6000 Evaluation Board. This is because PIC programming always starts from location 0000 and the program counter can only be incremented. e) Pressing A will display the program data in the bottom window, formatted in pages of 48 consecutive locations. Use the <PageUp> and <PageDown> keys to scroll through the data. Pressing <Esc> will return the user to the >ok prompt.

Evaluation Kit User Manual for PIC Board EV6000  1996 Consumer Microcircuits Limited 12 UM6000/3 1.6.2.2EV6020/EV6040 Diagnostic Firmware This is supplied both as a collection of assembler source routines on disk and pre-programmed into the PIC µC, where it is identified as EF6000. The diagnostic and applications firmware supplied may be replaced or supplemented by the user's own applications firmware. The PIC µC firmware is controlled by a terminal emulator program, from a PC with Windows 3.11, '95 or NT. Text commands are entered by the user into the terminal emulator. Characters are not case sensitive. There is a global limit of 6 characters on any user input string. Whenever the >ok prompt is displayed a new command may be entered and should be terminated by pressing the <Return> key. Whenever a command has been entered, the > prompt is returned if data entry is required. To use a function, the appropriate set-up commands must be entered before-hand. For example, to use the EV6040 to transmit external data to the line, the following should be entered: >ok 6040<Return>; sets EV6000 for use with the EV6040 >ok tx<Return> ; sets the FX604 into Tx mode >ok txext<Return>; select desired function The diagnostic commands are shown below. (a) Set-up commands: 6020Set board for connection to and control of EV6020. 6040Set board for connection to and control of EV6040. dbitSet FSK data format to 7 or 8 data bits. The user is prompted for the number of data bits. zp Set FX602/FX604 into zero power mode. zpirqSet FX602 into zero power mode, generating a pulse at the IRQN pin if ringing or a line reversal is detected. alertSet FX602 into tone alert detect mode. rx&txSet FX604 into Rx mode with back channel enabled. tx Set FX604 into Tx mode without data retiming. rx Set FX602/FX604 into Rx mode without data retiming. (b) Utilities:(Press <Esc> to exit these functions) f! Enter a mode where a 5 character string will write hex data to any register. PIC µC ports are mapped as registers. Use the format aa dd<Return> where aa is the register address in hex and dd is the data. f@ Enter a mode where a 2 character string containing a register address in hex will return the contents of that register. echoEnter a test mode where any text string entered by the user will be returned to the terminal emulator by the EV6000. dtmfEnter a mode where any DTMF digit entered by the user will be transmitted by the EV6020/6040.

Evaluation Kit User Manual for PIC Board EV6000  1996 Consumer Microcircuits Limited 13 UM6000/3 txaltEnter a test mode where a continuous "10101010" pattern will be transmitted at 1200 baud by the FX604. Press <Esc> to terminate this pattern. (c) Functions: (Press <Esc> to exit these functions) rxfskEnter a mode where FSK data received by the FX602/FX604 is interpreted as ASCII characters and displayed within the terminal emulator window. If the FX604 Tx back channel is enabled, then entering a 1 or 0 will change the state of the transmit data output. The FX602/FX604 is operated with data retiming selected. txtxtEnter a mode where text entered by the user or downloaded as a text transfer is transmitted by the FX604. The FX604 is operated with data retiming selected. txextEnter a mode where raw data can be applied by the user to connector J2 pin 2 on the EV6000 board for transmission at 1200 baud by an FX604 on the attached EV6020/EV6040 board. A clock output is provided on J2 pin 1 of the EV6000 board, the positive-going edge of which may be used to latch data on to J2 pin 2. rxextEnter a mode where raw data which has been received by an FX602 or FX604 at 1200 baud on the attached EV6020/EV6040 board can be read by the user on connector J2 pin 2 of the EV6000 board. A clock output is provided on J2 pin 1 of the EV6000 board, the positive-going edge of which may be used to latch data from J2 pin 2. Notes: Some terminal emulators have been found not to support full hardware flow control when transferring text files. This could result in data loss when using the txtxt command. If this problem is experienced, users should try using a lower data rate or a different terminal emulator. The PIC I/O line (J2 pin 1) which is used for the rxext and txext commands is an open-collector output with only a weak, 1M Ω , pull-up resistor fitted to the EV6000 board. When using either of the f! or f@ utilities, the register address equates to the following I/O ports:

05 PORT A

06 PORT B

07 PORT C

08 PORT D

09 PORT E

The individual lines of each port equate to EV6020 (and EV6040) connections as follows: _dtmf PORT A bit 0 _acload PORT A bit 1 _wp PORT A bit 2 _txline PORT A bit 3 _d3 PORT B bit 0 _d2 PORT B bit 1 _d1 PORT B bit 2 _d0 PORT B bit 3 _zp PORT B bit 4 ( _m0 for EV6040) _mode PORT B bit 5 ( _m1 for EV6040) _irqn PORT B bit 6 _det PORT B bit 7 _clk PORT C bit 0

Near end speech is input between TP18 and VSS (TP1 or TP2 ). If the detect output is set for a time longer than T1, the near end speech path (TP18 to the line) is muted. If the detect output then remains set (making a total detect time longer than T3 but less than 65ms) then, after a quiet period of 50ms, the DTMF digit "D" acknowledgement tone is transmitted down the line. Once this sequence has been completed, or aborted for not meeting a timing requirement, the near end speech path is un-muted and the FX602 returned to tone alert mode. On the EV6020 board, the line termination resistor R20 ( ≈ 600Ω ) should be fitted. Note that this software does not present an off hook dc load to the line. casdOperates as above, but two decimal counters are run. The first counts the number of times the near end speech is muted and the second counts the number of times the DTMF acknowledgement is sent. The results are displayed and updated in the form: M=00000000,A=00000000.> where M represents mutes of the near end speech path and A represents acknowledgement tones sent. On the EV6020 board, the line termination resistor R20 (≈ 600Ω ) should be fitted. Note that this software does not present an off hook dc load to the line. castThis enables the user to adjust the CAS detection algorithm timings T1 and T3. The user is prompted as follows: T1=3A98> Type <Return> for no change, or enter the new setting (in µs) in hex. e.g. For T1 = 10ms = 10,000µs = 2710hex, type 2710<Return> The user is then prompted to alter T3 in the same way. The default settings are T1 = 15ms = 3A98hex and T3 = 25ms = 61A8hex.

Evaluation Kit User Manual for PIC Board EV6000  1996 Consumer Microcircuits Limited 15 UM6000/3 cidcwThis demonstration covers both the BT and Bellcore off-hook caller ID services. The CAS detection algorithm runs as detailed for cas but once the DTMF acknowledgement is sent the FX602 is set to receive mode and the FSK data is displayed in the form of these examples: where 1 is the Message type word 2 is the Parameter type word 3 is the Parameter characters or data 4 is the Result of the checksum or in the following form: >80,A parameter.00, 1, 2, 3. where 1 is the Message type word 2 is the Message characters or data 3 is the Result of the checksum On the EV6020 board, the line termination resistor R20 ( ≈ 600Ω ) should be fitted. Note that this software does not present an off hook dc load to the line. clipThis demonstration covers the BT on-hook service initiated by a line reversal. On the EV6020 board, JP1 should be in position 2-3 for detection of a line reversal. The idle condition is with the FX602 in zero power mode and with IRQN enabled. When a line reversal is detected the FX602 is set to tone alert mode. Once the alert tone is detected the FX602 is set to receive FSK data, which is displayed in the same way as for cidcw. On the EV6020 board, relay 2 is energised for 15ms during the silent period between the alert tone and the FSK data. A resistor can be fitted in the R26 position to provide a current wetting pulse. Relay 3 is energised during the FSK receive period. Components can be fitted in positions R30, R36 and C10 to provide an ac termination to the line. cidThis demonstration covers the Bellcore on-hook service associated with ringing. On the EV6020 board, JP1 should be in position 1-2 for detection of ringing. The idle condition is with the FX602 in zero power mode and with IRQN enabled. A detect pulse of duration < 500ms is assumed to be a line reversal and is ignored. When a burst of ringing current is detected the FX602 is set to receive FSK data, which is displayed in the same way as for cidcw. On the EV6020 board, relay 3 is energised during the FSK receive period. Components can be fitted in positions R30, R36 and C10 to provide an ac termination to the line. nttThis demonstration covers the NTT on-hook service associated with ringing. On the EV6020 board, JP1 should be in position 1-2 for detection of ringing. The idle condition is with the FX602 in zero power mode and with IRQN enabled. A detect pulse of duration < 500ms is assumed to be a line reversal and is ignored. When a burst of ringing current is detected the FX602 is set to receive FSK data, which is displayed in the form of the following example:
