Crestron cnmsx User Manual

Crestron CNMSX 

Integrated Control System

 

This special consideration only applies to early production CNMSX units. These early 
units cannot be updated directly without updating an intermediary Monitor ROM first. 
If the CNMSX being updated has a Monitor ROM prior to v2.05 (this includes 
Monitor ROM 5.01.35 and lower), a dialog box shown below appears when 
attempting to update the control system. 

 

One can avoid jumping into the updating process by checking if the CNMSX has 
v2.05 or later (or v5.01.35 or later). Simply reboot the CNMSX while in Viewport. 
Cycle the power, depress the HW-R button on the front panel, or select Functions | 
Cold Reboot. The initial boot message appears and may be similar to the following. 
Notice that the Monitor ROM version is displayed in the first line.  

 

If the CNMSX has an early Monitor ROM, update the CNMSX by first using the 
50135x.upz file from the Crestron website (OPSYS Library). This UPZ file has no 
TCP/IP stack, so the checkbox for the TCP/IP stack is unavailable (grayed out). 

Finally, update to the latest UPZ file as listed in the OPSYS Library. The specific 
steps are provided in "Updating the Control System" on page 31.  

Problems may occur with the CNMSX itself or there may be serial communication 
difficulties with other devices connected to the CNMSX. The next two sections 
address possible problem solving tools or procedures for each.  

The table below and on the next page provides corrective action for possible trouble 
situations. If further assistance is required, please contact a Crestron technical support 
representative.  

Unexpected response 
from CNMSX.

Network devices are not 
communicating to the CNMSX.

From the Viewport, poll the network (F4) to verify communication.
