CNRACKX-DP
CNX Dual Processor Modular Control System
If communications with the CNRACKX-DP was not established, follow the steps in
this section to help remedy the problem. After performing each step, repeat step 7 in
on page 20 again.
1. Try repeating step 7 from
to attempt to
establish communications.
2. Verify that the cable being used is correct. It should be a straight-
through cable. That is, pin-1 on one end is connected to pin-1 on the
other end. Pin-2 connects to pin-2, etc. To work properly, pins-2, 3, and
5 must be connected.
3. Verify that the proper COM port on the PC has been selected. Some
PCs have more than one COM port, some of which may be internal
(e.g., for a modem). If verification can not be made, consult the user’s
manual or contact the PC manufacturer.
4. Check
the
NET
and
ERR
LEDs on the front of the CNRACKX-DP. If
either LED is illuminated, unplug the unit and reapply power after a
few seconds. If either LED illuminates again, call Crestron technical
support. Refer to
on page 33.
5. If steps 1 through 4 have failed to result in communications, the last
series of steps to perform is an overload/reset on the active processor.
Complete the following steps to do so:
5a. While the Viewport is displayed as shown on the next page, select
Functions | Set Baud Rate
(alternatively, depress
F8
) to open the
Set Baud Rate dialog box.
Accessing the Set Baud Rate Dialog Box
5b. Set the baud rate to 9600, as shown below.
