Port Device Type
There are two configurations of port types. The standard RS-232 is the basic configuration for transfer of
data. RPC-SNMP is allows the port to be monitored through SNMP protocol. The host module will poll the
port at a predetermined time based on the firmware and displays the RPC/RPS SNMP ID data from the unit
connect to the port on the host main menu. Default is RS-232 Type
NOTE: If no RPC/RPS with SNMP enabled device is connected to the port, the host module will
wait approximately 40 seconds for the port to respond to it’s polling upon power up or host module
unit reset and display the following: No communication with RPC at Module # Port #
Select the port you want to change the TYPE, followed by a <cr>.
The unit responds with the port’s current type.
Selecting either option the module responds with the DS74 Configuration Menu.
NOTE: Once you make a change to the port type, you have to back out of the Port Type menu and
will be asked to Accept changes. If you type ‘Y’ for YES, the changes take effect immediately for the
serial port.
