Warning: Some customers may want Linx radio frequency (“RF”) products to control machinery or devices remotely, including machinery or devices that can cause death, bodily injuries, and/or property damage if improperly or inadvertently triggered, particularly in industrial settings or other applications implicating life-safety concerns (“Life and Property Safety Situations”). NO OEM LINX REMOTE CONTROL OR FUNCTION MODULE SHOULD EVER BE USED IN LIFE AND PROPERTY SAFETY SITUATIONS. No OEM Linx Remote Control or Function Module should be modified for Life and Property Safety Situations. Such modification cannot provide sufficient safety and will void the product’s regulatory certification and warranty. Customers may use our (non-Function) Modules, Antenna and Connectors as part of other systems in Life Safety Situations, but only with necessary and industry appropriate redundancies and in compliance with applicable safety standards, including without limitation, ANSI and NFPA standards. It is solely the responsibility of any Linx customer who uses one or more of these products to incorporate appropriate redundancies and safety standards for the Life and Property Safety Situation application. Do not use this or any Linx product to trigger an action directly from the data line or RSSI lines without a protocol or encoder/ decoder to validate the data. Without validation, any signal from another unrelated transmitter in the environment received by the module could inadvertently trigger the action. All RF products are susceptible to RF interference that can prevent communication. RF products without frequency agility or hopping implemented are more subject to interference. This module does have a frequency hopping protocol built in, but the developer should still be aware of the risk of interference. Do not use any Linx product over the limits in this data guide. Excessive voltage or extended operation at the maximum voltage could cause product failure. Exceeding the reflow temperature profile could cause product failure which is not immediately evident. Do not make any physical or electrical modifications to any Linx product. This will void the warranty and regulatory and UL certifications and may cause product failure which is not immediately evident.

Description

The HumRCTM Series transceiver is designed for reliable bi-directional remote control applications. It consists of a highly optimized Frequency Hopping Spread Spectrum (FHSS) RF transceiver and integrated remote control transcoder. The FHSS system allows higher RF output power and, therefore, longer range than narrowband radios. Eight status lines can be set up in any combination of inputs and outputs for the transfer of button or contact states. A selectable acknowledgement indicates that the transmission was successfully received. Versions are available in the 900 and 2.4GHz frequency bands. Primary settings are hardware-selectable, which eliminates the need for an external microcontroller or other digital interface. For advanced features, optional software configuration is provided by a UART interface; however, no programming is required for basic operation. The evaluation module contains the surface mount HumRCTM Series transceiver module and an MMCX connector on a single board with through-hole headers. This small board simplifies prototyping with the HumRCTM Series module. HumRC TM Series Evaluation Module Data Guide Revised 8/12/2015 Figure 1: HumRCTM Series Evaluation Module

7 MODE_IND O

This line indicates module activity. It can source enough current to drive a small LED, causing it to flash. The duration of the flashes indicates the module’s current state. 8 RESET2 I This line resets the module when pulled low. It should be pulled high for normal operation.

9 CMD_DATA_IN I

Command Data In. Input line for the serial interface commands. If serial control is not used, this line should be tied to ground or POWER_DOWN to minimize current consumption.

10 POWER_DOWN I

Power Down. Pulling this line low places the module into a low-power state. The module is not functional in this state. Pull high for normal operation. Do not leave floating.

11 LATCH_EN I

If this line is high, then the status line outputs are latched (a received command to activate a status line toggles the output state). If this line is low, then the output lines are momentary (active for as long as a valid signal is received). Pin Descriptions Pin Descriptions Pin Number Name I/O Description 12, 22–25, 26–37, 47-56 NC — No Electrical Connection. Do not connect any traces to these lines.

13 ACK_EN I

Pull this line high to enable the module to send an acknowledgement message after a valid control message has been received.

14 PAIR1 I

A high on this line initiates the Pair process, which causes two units to accept each other’s transmissions. It is also used with a special sequence to reset the module to factory default configuration. 15 CMD_DATA_OUT O Command Data Out. Output line for the serial interface commands

16 LNA_EN 0

Low Noise Amplifier Enable. This line is driven high when receiving. It is intended to activate an optional external LNA.

17 VCC — Supply Voltage

18 LVL_ADJ I Level Adjust. The voltage on this line sets the transmitter output power level.

19 C0 I

This line sets the input/output direction for status lines S0–S3. When low, the lines are outputs; when high they are inputs.

20 PA_EN O

Power Amplifier Enable. This line is driven high when transmitting. It is intended to activate an optional external power amplifier.

21 C1 I

This line sets the input/output direction for status lines S4–S7. When low, the lines are outputs; when high they are inputs. 38-45 S0–S71 I/O Status Lines. Each line can be configured as either an input to register button or contact closures or as an output to control application circuitry.

46 ACK_OUT O

This line goes high when the module receives an acknowledgement message from another module after sending a control message. 1. These lines have an internal 20kΩ pull-down resistor 2. These lines have an internal 10kΩ pull-up resistor Figure 6: EVM-xxx-RC Pin Descriptions Pin Assignments Warning: This product incorporates numerous static-sensitive components. Always wear an ESD wrist strap and observe proper ESD handling procedures when working with this device. Failure to observe this precaution may result in module damage or failure.
