Configuring the Data Port
To conÞgure a data port, use Menu-5 Data Port ConÞguration.
Set the parameters for the local and remote units.

Figure 3-3 Menu-5 Data Port ConÞguration
The example in Figure
3-3 shows the local DL600E unit with four data
ports in use. The remote unit is a DL600E unit with one data port.
The Data Port parameters and their options are:
LossÑDTR (Data Terminal Ready), RTS (Request to Send) or NONE
(DefaultÑ
RTS)
Select the criteria for detecting loss of signal on the data port. The
loss appears when detected by the DL600E unit.
MODEÑDTE or DCE (DefaultÑDCE)
ConÞgure the data port as a DTE (Data Terminal Equipment) or a
DCE (Data Circuit Equipment). Each requires a different cable.
When DCE, both SCT and SCR are derived from a single smooth
clock source requiring the synchronization of the transmit and receive
directions, each directions derived from the same timing source.
When
DTE, the data port ignores the SCT signal and uses SCR to time
both the send and receive signals.
