Figure 7.1 Null Modem Cable connection
The null modem cable will cross pins 2 and 3 (RXD
and TXD). On the computer end of the cable, pins 7
and 8 (RTS and CTS) should be connected together.
Also pins 1, 4, and 6 (DCD, DTR and DSR) should be
connected together. The cable diagram is illustrated in
Figure 7.1. In addition, the DIP switches on the front of
the DTU3005B unit must be set to configuration mode
as described below.
1. Power down the DTU3005B unit.
2. Set the DIP switches to configuration mode per
the DIP switch settings listed below in Table 7.1
and shown in Figure 7.1.
3. Restart the DTU3005B unit.
4. The status LED on the front of the DTU3005 unit
flashes green to indicate that the unit is in config-
uration mode.
Note: To return the device to normal opera-
tion, the DTU3005B unit must be pow-
ered off while the DIP switch settings
are reset, then the unit will be in normal
operation mode when it is powered up.
