LocoNet DCC Occupancy Detector with Transponding
and Power Management for 8 Detection Sections,
Transponding Zones, and Power Sub-Districts
Features:
▪
DCC Occupancy Detection supports up to 8 Detection Sections letting you
know when equipped rolling stock is in a detection section on your layout.
▪
One Transponding Zone per Detection Section lets you know the location of
transponder-equipped locos or rolling stock.
▪
Intelligent Automatic short-circuit and over-current power management
for each Detection Section, improves reliability by avoiding most booster
shutdowns.
▪
Connects to LocoNet to transmit Detection Section occupancy, Transponding
and track power information.
▪
Detects any powered locomotives in a Detection Section.
▪
Detects rolling stock equipped with resistor wheel sets.
▪
Identify where specific rolling stock is on your layout with Digitrax transpon-
der-equipped locos and rolling stock.
▪
Plug and Play with Digitrax DCC systems with automatic Railsync polarity
detection.
▪
LED output headers for front panel indication of Detection Section occupancy,
Transponding, and power status.
▪
Easy-connect pluggable track wire terminal blocks can plug-in straight or at
right angles.
▪
3 Amp capacity per Detection Section , 8 Amp total unit capacity.
▪
Automatically updates status at track power on.
▪
Operations Mode Read Back allows you to read CV values of decoders
equipped with transponders when on track.
▪
Firmware update capability via IPL over LocoNet.

- Page 2 DCC track management by communicating all state information to LocoNet. The BXP88 provides DCC occupancy detection that lets you know when any of its 8 connected Detection Sections are occupied by rolling stock that is equipped for detection.
- Page 3 Power district is the power wiring, track, components and equipment attached to that wiring, driven by a single properly isolated booster. The track for a power district is double gapped on both ends of the district. The BXP88 is used to set up detection/transponding sections within one power district.
- Page 4 It is best to plan your detection sections based upon the operations you want to accomplish on your layout before cutting track gaps and installing a BXP88 or other detection devices. For instance, a grade level signal crossing may require from two to four different detection sections with occupancy detection in order to control the lights and gates operating, for trains traveling in either direction.
- Page 5 BXP88 can be switched as needed to match existing wiring, the BXP88 automati- cally sets railsync. An LT5 tester is included with the BXP88, and optional fascia LED panels can be constructed following the instructions in section 10.3 . The BXP88 does not need to be externally powered. An optional auxiliary 9V 150ma DC power supply may be used to allow the BXP88 to remain on when track power is lost.
- Page 6 6.0 Turning on your system and configuring the BXP88 Once you have installed your BXP88, you may turn on your system. There are several tests you can perform to ensure that the BXP88 is properly functioning. Power on your Digitrax System and the sections of your layout where the BXP88 is connected.

- Page 8 Setting up your Board ID for your BXP88s should be carefully considered. Each BXP88 automatically assigns Detection Sections and Transponding Zones based off the BXP88’s Board ID. For example, a BXP88 with a board ID of 001 (factory default) will report for detection sections 01-08 and transponding zones 00-07.
- Page 9 SWITCH mode is normally used for operating turnouts by issuing closed (“c”) or thrown (“t”) commands. In the case of your BXP88, each switch address is a BXP88 option switch when it is in OPSW setup mode. How to read back and change BXP88 Option Switches (OpSw): Power up your BXP88 and connect it to LocoNet.
- Page 10 Transponding will work. An upstream auto-re- verser will reverse all of a BXP88’s detection sections tracks, so these 8 detection sections can only be used within the same single reverse area or power district.
- Page 11 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.
- Page 12 1~3mA. If you need higher LED drive currents you can use external transistors etc. to amplify the LED current. The LT5 header drive from the BXP88 is active high at about +3.5 volts, via a 1 Kohm resistor. Note that the ribbon cable includes separate ground return conductors for each LED that allow a 10 conductor ribbon cable to be split into 5 pairs to conveniently routed to individual LEDS.
- Page 13 NOTE: Locos must be selected in the system for transponding to work. 12.0 Occupancy Debug Use the LT5 provided or attached LED indicator panel with your BXP88 as described in Sections 10.2 & 10.3. The LT5 tester or and attached LED indicator panel allows you to easily check the zone sensitivity (typically 22 Kohms to give detection).

Page 14: Fcc Information
Many detection problems are related to wiring problems or poor connections to the detection section rather than to the actual BXP88. By using the display array, you can eliminate the wiring issues from the equation and be sure that the BXP88 is set up correctly. -
