Output Commands

The output commands allows the output to be enabled (disabling input 1). Following configuration

of the pins as outputs, they are controlled using the WTE Output Control Protocol.

Note: Please refer to Input Output Hardware Connection section on this manual for ex-

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

*OUT_CONFIG

*OUT_CONFIG specifies all output configuration items, usage as follows:

*OUT_CONFIG=O:E,T <CR>

Where:

O = The output to configure (only 1 valid)

: = the character ‘:’

E = 1 to enable the set GPIO pin to an output.

T = time for output to close for in 100ms steps. E.g. 100 is 10 seconds. Max value is

32000. Setting to 0 disables the timer and output is latched indefinitely.

Example:

*OUT_CONFIG=1:1,100<CR>

*UNIT_ID

*UNIT_ID specifies the output unit ID

*UNIT_ID=XX<CR>

where:

XX are any characters (up to 12 either numeric or alphanumeric) that are used to uniquely

address each MReX when used in conjunction with the WTE Output Control Protocol.

By default this ID is “01”, allowing numeric paging to be used to transmit messages.

Example:

*UNIT_ID=01<CR>

Note: Inputs can still be enabled while the GPIO is configured to be an output. This has been

allowed to permit a message to be received, then reply immediately with a preprogrammed

message that has been configured on that same pin. In this manner the MReX can transmit any

message reporting when an output has changed state.
