Configuring the Modem to Transmit or Receive
The Coral IPx 500 modem can be configured to transmit or receive data. This is useful
when maintenance from a remote workstation is necessary. During normal system
operation, it is advisable to set the modem transmit and receive function to “Off” for
more secure system operation.
