Communication Port
Table 4-17. Communication Port Options (1 of 5)
Port Use
Possible Settings: Terminal, Net Link
Default Setting: Terminal
Assigns a specific use to the COM (Terminal) port.
NOTE: If the Default IP Destination is set to COM (see Table 4-10, Node IP
Options) and you change Port Use to Terminal, the Default IP Destination
is forced to None.
Terminal – The COM (Terminal) port is used for the asynchronous terminal connection.
Net Link – The COM (Terminal) port is the network communications link to the
IP network or IP device port.
NOTE: If the COM port configured for Net Link is used to connect to an external
modem, there is a potential security risk of an unauthorized user gaining
access to the NMS or other devices on the LAN for which this device has
routing table entries.
Data Rate (Kbps)
Possible Settings: 9.6, 14.4, 19.2, 28.8, 38.4, 57.6, 115.2
Default Setting: 19.2
Specifies the rate for the COM (Terminal) port in kilobits per second.
9.6 – 115.2 kbps – Sets the communication port speed. The 57.6 and 115.2 speeds are
not available on the Model 9820-45M.
Character Length
Possible Settings: 7, 8
Default Setting: 8
Specifies the number of bits needed to represent one character.
NOTE: Character length defaults to 8 and cannot be changed if Port Use is set to
Net Link.
7 – Sets the character length to seven bits.
8 – Sets the character length to eight bits. Use this setting if using the COM port as the
network communication link.
