UMX-TP-TX100R

Programmer’s Reference Manual

Section 3. Operation modes Page 13 / 43

2. In case of the second mode the TX lines of the processor are in HiZ state and the

serial connectors on the transmitter and on the receiver are linked together through

the DDC CAT cable.

Mentioning the facts above is important as there are two commands to set the operation:

{RS232=CONTROL}

Sets the mode when you can control the unit.

{RS232=PASS}

Sets the mode when the serial connector is used as a

serial link towards the receiver unit.

{RS232=?}

Queries the actual state, the response will be

(RS232=CONTROL) or (RS232=PASS).

For more information see section 4.4.5 on page 18.

Info: UMX-TP-TX100R stores the RS232 working mode and starts the saved one after reboot.

The default baud rate for control is 57600, the command to set the baud rate can be the

following:

{RS232BAUD=9600}

{RS232BAUD=19200}

{RS232BAUD=38400}

{RS232BAUD=57600}

{RS232BAUD=115200}

Of course in PASS mode the speed can be anything, but for changing and querying the

mode the previously set baud rate must be applied for the sent commands.

For more information see section 4.4.2 on page 17.
