Revision 1.11 Page of 2 Jan. 2011 Operation Manual for USB Converter Board V1.11 The function of kit DAC02 is to convert UART signal to USB signal and provides the interface for customers to configure the settings of modules through PC software tool. This manual demonstrates how to use DAC02 in setting mode and normal work mode for different modules. 1. In Setting Mode The RF FSK modules provided by DORJI are mainly based on RFICs from Silicon labs, ADI and Semtech. DORJI provides two software tools for different RF modules. The USB converter board has a 6-hole socket but for DRF1212, DRF4432 and DRF7020D13/20 modules they have 7 pins so the 7 th pin of modules must be kept in floating status in connection. The Pin 1 (marked as 1 on the top of USB board) is corresponding to the Pin 1 (GND pin) of RF modules. Figure 1: Connecting Status When configuring module, users should insert the module into USB converter board correctly and connect it to PC and then open software tool. After the tool finds the module and shows “Found device” in the status line at the bottom, users then can write/read modules through corresponding buttons. After successful operation, the message “Write succeed” or “Read succeed” will be showed in the status line. Module Type Software Tool DRF1212D10, DRF4432D20 DRF Tool for 1212/4432 series DRF7020D series, DRF7020M series DRF Tool for ADF702X series Table 1 Module Type Vs Software Tool Note: If the software tool is run before module is connected to PC, an alert window will show up and display “No serial port is found”. Users only need to click the button to confirm, close and reopen the tool after module is connected correctly. 2. In Normal Work Mode The main function of USB converter board is to configure modules through PC so the kit is not tailor-made for testing communications between modules. Different modules have different level requirements on control pins in order to work in normal mode. The table
Revision 1.11 Page of 2 Jan. 2011 below shows the difference among modules. SET-A/EN SET-B/SET Module Type LO LO/HI DRF1212D10 LO HI DRF4432D20 HI HI DRF7020D series, DRF7020M series Table 2 Level Controls in Normal Communication Mode 1) For DRF1212 modules, the 3 rd pin is SET-A and the 7 th pin is SET-B. In normal communication mode, the SET-A must be low and SET-B can be low/high (Normal mode/Wake-up mode). The USB converter board uses IC CP2102 from Silicon labs a nd its RTS pin is corresponding to SET-A pin of DRF1212 module. In order to test communication between modules succe ssfully, users should choose serial port software which provides RTS option and keep RTS selected so that the SET-A pin is pull down and the DRF1212 modules will work in wake-up mode. 2) For DRF4432 modules, the 3 rd pin is Enable pin and in normal wo rk mode it must be set to low. The 7th pin is Data/field strength indication pin. When it is sent to high, the module outputs normal data or else it outputs field strength value. For the same reason, DRF4432 modules must be tested by serial port software with RTS option. 3) As to DRF7020D/7020M series, the 3 rd pin is Enable pin and in normal mode it must be set to high. The 7th pin is SET pin and it is set to low when modules need to be configured. These series of modules can work correctly when tested under common serial port software.
