Status LED's
Communication Port
The RS485 port has two LEDs to show the flow of data between the URC-2000
controller and PC. The red RX LED (LED1) flashes when the controller receives data.
The green TX LED (LED2) flashes when the controller transmits data. If the controller
is connected directly to the PC, the status LED's flash continuously.
Run LED
The run LED (LED3) flashes to indicate the controller is not communicating, it is on
solid when running normally, and off if power is missing.
Fuses
There are two 1-amp self-resetting Polyfuses on the URC-2000 board. F1 is connected
to Reader Power and F2 is connected to Main Power.
