Controller Command List

2
IP Control Settings
The RA-1572 will only accept and respond to IP control commands if the product is
connected to a local network and has a valid IP address.
Commands will be accepted via TCP port 9590, and the unit will send responses back via
the same port. The command and response format is identical to the serial commands.
Communication Protocol
Command and response messages are included on the following pages.
Automatic status update information can be enabled/disabled using the
“rs232_update_on” and “rs232_update_off” commands (V2.0) or “display_refresh_auto”
and “display_refresh_manual” commands (V1.0).
With RS232 update set to ON, any status changes to the unit will be transmitted via
RS232. With RS232 update set to OFF, the unit will not send any feedback unless polled
by the controller.
