Crestron CNAMPX-7X200 7 Channel Surround-Sound Amplifier
Identity Code
Every equipment and user interface within the Cresnet system requires a unique
identity code (NET ID). These codes consist of a two-digit hexadecimal number
from 03 to FE. The NET ID of the unit must match an ID code specified in the
SIMPL Windows program. The NET ID of the CNAMPX-7X200 is factory set to 3F.
The NET IDs of multiple CNAMPX-7X200s in the same system must be unique.
NET IDs are changed from a personal computer (PC) via the Crestron Viewport.
Complete the following steps to change the NET ID.
NOTE: For detailed information on establishing communication between the PC
and Control System, refer to the network’s Control System Operations Guide.
1. Ensure that the CNAMPX-7X200 is the only device connected to the
control system (verify that the software is running).
2. Open the Crestron Viewport.
3. From the Viewport menu, select Functions | Set Network ID. The
software checks the baud rate and then opens the “Set Network ID”
window.
4. In the “Set Network ID” window, select the CNAMPX-
7X200 from the
Current Network Devices text window.
5. From the Choose the new network ID for the selected device (Hex): text
box, select the new Net ID for the CNAMPX-
7X200.
6. Click Set ID to initiate the change. This will display the “ID command
has been sent” window.
7. In the “Command Complete” window, click OK.
8. In the Current Network Devices text window, verify the new NET ID
code.
9. In the “Set Network ID” window, click Close.
NOTE: The new NET ID code may also be verified by selecting Diagnostic |
Report Network Devices in the Viewport (alternately, select F4).
10. Repeat this procedure for each CNAMPX-7X200 to be added to the
system.
