Restrictions

Requires privileged user status.

Errors

Only applies to the MSS-VIA and the MSS4 (the MSS485 is configured via

 

jumpers).

Parameters

Port

 

MSS4 only. Specifies a particular port or group of ports.

Note:

In the absence of the PortList parameter, the configuration will affect the MSS4’s

 

current port only.

 

PortList

 

Specify a particular port or group of ports. Port numbers are specified with

 

integers between 1 and 4, and should be separated with commas (for lists) or

 

dashes (for ranges).

 

Enabled/Disabled

 

Enables or Disables RS-485 mode. By default, the MSS is configured for RS-

 

232 networking.

 

Mode

 

When RS-485 Mode is enabled, you must choose either two-wire or four-wire

 

mode. If you do not explicitly set a mode with this command, the MSS will

 

default to four-wire mode.

 

2Wire

 

Sets the MSS to use two-wire mode.

 

4Wire

 

Sets the MSS to use four-wire mode.

Enable termination whenever you are using long cable runs and Disable it at

 

other times. Only end nodes should be terminated.
