DCD (Data Carrier Detect)

Option Values: follow, ignore

Applicable Data Protocols: All

This option determines whether the ADM turns on the Data Carrier Detect (DCD) lead when a

data call is in progress, and off when one is not (follow), or whether it keeps DCD on essentially

all the time (ignore).

If your data terminal transmits data only when the Data Carrier Detect lead is on, set DCD to

ignore. When the DCD lead is set to ignore, it appears to your terminal that a data call is always

present, except for one second following termination of a call. This enables your data terminal to

transmit commands to the ADM even when a data call is not present. This setting is appropriate

for most users.

Set the DCD lead to follow only if your application requires that Data Carrier Detect be off when

a data call is not present. Select follow also if your application will not enter data mode unless it

sees the Data Carrier Detect go from off to on.

See the instruction manual for your data terminal or PC application package to determine which

setting is appropriate.

DTR (Data Terminal Ready)

Option Values: follow, ignore

Applicable Data Protocols: All

Data Terminal Ready (DTR lead) is an electrical signal sent from your data terminal to the ADM.

The DTR option determines how the ADM responds to the presence or absence of this electrical

signal. The DTR lead is used by your data terminal to indicate to the ADM that it is ready for

communication. Many data terminals turn the DTR lead on whenever the data terminal is turned

on. If your data terminal works this way, setting the DTR option to follow enables you to end

data calls by turning off your data terminal. If you want to retain active data calls when your

data terminal is turned off or while you change EIA cables, set the DTR option to ignore.

If your application turns the DTR lead off during file transfer, set the DTR option to ignore.

Interactions with Answer: If the DTR option is set to follow and Answer is set to auto, the

ADM automatically answers data calls only when the DTR lead is on. If the DTR option is set to

ignore and Answer is set to auto, the ADM automatically answers whether the DTR lead is on or

off.

Echo

Option Values: on, off

Applicable Data Protocols: All

This option determines whether characters sent from the data terminal in Data Mode are echoed

by the ADM.
