7.0 DB9 DTE RS-232
Connector (P6)
The DX4010V2 serial port is wired as a DTE device.
•
If the connected device is a data carrier
equipment (DCE) device (most common, such
as an external modem), use a straight through
9-pin to 9-pin, or (DTE to DCE) 9-pin to 25-pin
cable.
•
If the connected device is a DTE device (such
as a PC serial port), a null-modem (DTE to
DTE) 9-pin to 9-pin, or null-modem 9-pin to 25-
pin cable is required.
Consult the operating manual provided with your
compatible device for wiring requirements.
If you are using an alternate configuration, you
must make a custom cable (refer to
Figure 8
and
Table 5)
.
