7. Select Diagnostics | Check Operating System Version (alternatively,

depress F5) from the Viewport. The Viewport may display a window

as it scans various baud rates. Eventually, a message should appear in

the Incoming section showing a version number. Such a response

indicates that communications have been established.

If a “No Communications with Rack” error message opens, proceed to

“Troubleshooting Communications” on page 20. If the baud rate of the

CN-TVAV was something other than 38400, the software

automatically adjusts the baud rate to 38400.

Establish Remote Console Connection

Instead of communicating by plugging into each CN-TVAV in a large installation

via RS-232 in order to upload programs/firmware/etc., the CN-TVAV console can be

accessed from the control system to which it is a peripheral. Complete the following

steps to establish communication with the CN-TVAV.

1. If using the Stand-alone Viewport, open the Viewport and proceed to

step 4. To access the Viewport via SIMPL Windows, select Start |

Programs | Crestron | SIMPL Windows to start SIMPL Windows.

NOTE: SIMPL Windows may open with an opening splash screen and may display

the “What do you want to do?” dialog box. If so, close the dialog box and continue.

2. Select Tools | Viewport to open the Crestron Viewport.

3. Refer to the documentation supplied with the host control system and

verify communication with the host control system.

4. From the Viewport menu, select Remote | Remote Console | Connect

as shown below.

Troubleshooting Communications

If communications with the CN-TVAV has not been established, follow the steps in

this section to help remedy the problem.

1. If a program is already loaded into CN-TVAV, refer to “Special

Considerations for Using the RS-232 Port for Uploading Programs” on

page 9 for further information.

2. Verify that the cable being used is correct. (If cable is not available,

refer to “Programming Cable Fabrication Specifications” on page 9.)
