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:
Loss
Ñ DTR (Data Terminal Ready), RTS (Request to Send) or NONE
(DefaultÑ RTS)
Select the criteria for detecting loss of signal on the d ata port. The
loss appears when detected by the DL600E unit.
MODE
ÑDTE or DCE (DefaultÑ
DCE)
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.
