MReX Transceiver User Manual v1.92 Firmware

Input Commands

The input commands allow messages to be configured for transmission when changing state. De-

bouncing (how long an input is settled before acting on the new level) can be configured with the

number of times to transmit the input message.

Note: Even if an input is configured to transmit a certain number of messages, should the in-

put level change before all messages are transmitted, then the remaining transmissions will be

cancelled.

Please refer to Input Output Hardware Connection section on this manual for examples of

how to connect the input and output pins on the MReX board.

*IN_CONFIG_L

*IN_CONFIG_L specifies all input Low configuration parameters. Inputs are triggered by con-

necting the input to ground for a time exceeding the specified debounce period. The input message

is configured using the *IN_MSG_L command. Usage is as follows:

*IN_CONFIG_L=I:N,D,R

Where:

I = The input to configure (1-5 valid)

: = the colon character ‘:’

N = number of transmissions (0 = no transmissions, 9 is max tx count)

, = the comma character ‘,’

D = debounce in 100 ms steps (from 0-255)

, = the comma character ‘,’

R = time in seconds between retransmissions.

Example. Configure input 1 to send two message after input is debounced by 300 milliseconds and

repeat/retransmit this message 4 times.

*IN_CONFIG_L=1:2,3,4<CR>

*IN_CONFIG_H

*IN_CONFIG_H specifies all input High configuration parameters. Inputs are triggered by mov-

ing the input to a high state or released from GND for a time exceeding the specified debounce

period. The input message is configured using the *IN_MSG_H command. Usage is as follows:

*IN_CONFIG_H=I:N,D,R

Where:

I = The input to configure (1-5 valid)
