Diagnostic LEDs
LD1 – Front Panel indication of system and B-BUS operation. When the Tx1500 is properly configured with the
correct number of keyboard and alarm cards connected the led appears to be on but pulsing very quickly. If
communication with a keyboard or alarm card fail or if the Tx1500 is configured incorrectly then the led will flash
at a noticeably slower rate i.e. 2 flashes per second.
Internal LEDs,
LD2 – BBV debug use.
LD3,4,5,6 – ON whilst coaxial telemetry is transmitted to the camera which is being viewed on Mon 1,3,2,4
For normal operation the internal switches must be as shown below:
Switches 7 & 8 must be on
when the Tx1500 is at the end
of line. This will be when a
single RS485 connection is
used.

Setting the switches as shown below will carry out a factory default. The procedure is to power off the Tx1500,
set the switches and then power on the T x1500. On screen instructions are displayed on monitor 1 output.
