SEND mode

In the SEND mode, the transmitter will automatically output one

message at power-up or when triggering the transmitter on using pin 4

of the transmitter. The trigger signal must be a TTL level signal. TTL

HIGH (5 VDC) turns the transmitter ON and TTL LOW (0 VDC)

turns the transmitter OFF.

Examples of outputting with the prompt (ECHO ON) and without the

prompt (ECHO OFF):

>echo <cr>

Echo : ON

>smode send <cr>

Serial mode : SEND

>reset <cr>

1013.25 hPa

>echo off <cr>

excluding the <cr> and <lf> characters, the pressure unit and the

decimal point with the FORM command:
