Network Analyzer

Battery Replacement

A Lithium battery is used to power the system clock within the 2-Series integrated

dual bus control system. Under normal conditions, it will last for approximately 10

years. In the event that the clock fails, only an authorized technician should replace

it. Refer to caution statement below.

CAUTION: Danger of explosion if battery is incorrectly replaced.

Replace only with the same or equivalent type recommended by the manufacturer.

Dispose of used batteries according to the manufacturer's instructions.

Serial Communication Difficulties with Other

Devices Connected to the Control System

Passthrough Mode

Passthrough mode allows data to pass directly from the COMPUTER port to the

selected COM port on a Cresnet or Ethernet device (such as ST-COM or CEN-

COM), effectively “passing through” the control system. This makes it possible to

determine if the communication problem is in the control system or in the device

itself. While passthrough mode is running, the program currently in memory is

suspended and will not execute. When passthrough mode is exited, the program

resumes operation. The TX and RX LEDs for the given port illuminate when in

passthrough mode.

Entering passthrough mode for one of the internal COM ports reinitializes it, which

clears the data for that port. The COM analyzer also functions while the unit is in

passthrough mode.

Passthrough mode is accessed from the Crestron Viewport by selecting Functions |

Enter Passthrough Mode (CNX / 2-Series only). The window, shown after this

paragraph, is used to select the port configuration for passthrough mode. For more

information, refer to the Viewport Help files.
