36 TCP/IP AX3000 User's Manual
3.5.1 - Setting the AUX1 and AUX2 Serial Ports
Select the [Configuration]→[Aux. Ports]→[AUXx] dialog box to configure
each auxiliary serial port:
The [TEST] button allows communication between the AX3000 auxiliary port
and the device to be tested. Whatever the auxiliary port status (TCP/IP
connection established or not), when this button is 'pressed', data is sent from
the AX3000 port to the device.
Note: when a new value is given to a parameter (speed, handshake, etc.), the
AX3000 Set-Up must be exited (with saving settings) before testing the port.
