Operation
9.3. Connecting and Disconnecting Serial Ports - Text Interface
The Text Interface can also be used to create connections between RSM-8R4 serial
ports. This allows you to access the console port of a connected device, or allow
connected devices to access the RSM-8R4's internal modem or network port.
Note: The Web Browser Interface cannot be used to connect or disconnect
ports. In order to connect or disconnect ports, you must access command
mode via the Text Interface.
As discussed in Section 5, There are four available operating modes for the RSM-8R4
serial ports: the Any-to-Any Mode, the Passive Mode, the Buffer Mode and the Modem
Mode.
9.3.1. Any-to-Any Mode
Any-to-Any Mode Ports can be connected to other Any-to-Any, Passive, Buffer, or
Modem Mode ports by accessing command mode via the Text Interface and issuing
the /C Command. All ports can be configured for Any-to-Any Mode, and it is also the
default mode for Ports 1 and 2.
9.3.1.1. Connecting Ports
Two different types of connections can be made between RSM-8R4 serial ports;
Resident Connections and Third Party Connections The RSM-8R4 allows
communication between devices without the requirement that both ports use the same
communication parameters.
Resident Connections: Your resident port issues a /C command to connect to a
second port. For example, Port 4 issues the /C command to connect to Port 5.
Third Party Connections: (Administrator and SuperUser Mode Only) Your resident
port issues a /C command to create a connection between two other ports. For
example, Port 1 is your resident port, and Port 1 issues a command to connect
Port 2 to Port 3.
Notes:
Third Party Connections can only be initiated by accounts and ports that
permit Administrator or SuperUser level commands.
The serial ports cannot employ the /C command to initiate a connection to
the Network Port.
User level accounts are only allowed to connect to ports that are specifically
allowed by the account. Administrator and SuperUser level are allowed to
connect to all serial ports.
