This section describes how to manually update bus device firmware.

1. Switch the Net Bridge  switch to STANDBY.
2. Switch the Net Bridge MODE switch to SETUP.
3. Switch the Net Bridge  switch to ON.
4. Wait for one minute and see if the FUNC and RS-485 leds blink orange.
   • If they do, there are bus devices that are undergoing a firmware update. Wait until the FUNC led is switched off and RS-485 led is constantly illuminated green.
   • If they do not, continue from step 5.
5. Switch the Net Bridge MODE switch to OPERATING.
6. An internal test procedure is started.

   Observe the green FUNC led for approximately one minute until the Net Bridge has saved the bus configuration. Check that:

   1. The green FUNC led blinks as many times as there are devices on the main bus.
   2. After a pause, the green FUNC led blinks as many times as there are devices on the reader buses.
   3. After a pause, the green FUNC led blinks as many times as there are lock cylinders connected on Door Modules.

   The procedure ends when constant green FUNC, RS-485 STATUS, SYSTEM STATUS, and SERVER CONN. leds are illuminated.
