10.0 Occupancy/Transponding Indication

The BXP88 can report occupancy and Transponding information via the LocoNet

connection or via direct output to a user created LED panel.

10.1 LocoNet Devices

The BXP88 provides occupancy and transponding messages to LocoNet that can

be used by computer software for a visual display of occupancy and transponding

status on the layout or to other devices on the layout. For instance layout control

software can use these messages to control signals on the layout via a Digitrax

SE8c. See the operating manual of your computer software or the SE8C for de-

tails on installation and operation.

10.2 LT5 Tester

The BXP88 provides two LT5 LED compatible outputs labeled "DS1-4 LEDS"

and "DS5-8 LEDS" and the supplied LT5 tester can be plugged in here to provide

visible detection section, power state and fault information for setup, debug and

running. This will help you with layout wiring and troubleshooting for transpon-

ding & detection.
