Specifies the type of line that is being used with the Device Server. Select either

EIA-232, EIA-422, or EIA-485.

Specifies whether the RS-232 signal DCD (Data Carrier Detect) should be monitored.

This is used with modems or any other device that sends a DCD signal. When it is

monitored and the Device Server detects a DCD signal, the line service is started.
Default is

Off

. If both

Monitor DCD

and

Monitor DSR

are enabled, both signals must be

detected before the line service is started.

Specifies whether the RS-232 signal DSR (data set ready) should be monitored. This is

used with modems or any device that sends a DSR signal. When it is monitored and the
Device Server detects a DSR signal, the line service is started. Default is

Off

. If both

Monitor DCD

and

Monitor DSR

are enabled, both signals must be detected before the

line service is started.

Used with a

EIA-485

serial interface, if your application supports

RTS

(Request To

Send), select this option. Otherwise, select

Auto

. Default is

Auto

.

Specify whether the line is

Full Duplex

(communication both ways at the same time) or

Half Duplex

(communication in one direction at a time).

This parameter applies only to

EIA-485

Half Duplex

mode. All characters will be

echoed to the user and transmitted across the serial ports. Some EIA-485 applications

require local echo to be enabled in order to monitor the loopback data to determine that
line contention has occurred. If your application cannot handle loopback data, echo

suppression should be

On

. The default is echo suppression

Off

.

Specifies the baud rate of the line; keep in mind that speed is affected by the length of

the cable.
