to other rolling stock without decoders if you want to use them for transponding

only and don't need motor control.

Transponder detector is an electronic device as part of a detection section on

the layout that receives the information broadcast from a transponder. The tran-

sponder detector sends feedback to the system to let it determine the detection

section location of any given transponder at any time. The BXP88 incorporates

transponding and occupancy detectors in each of its 8 detection sections.

Transponder zone is an area of track that may be single gapped on one rail or

double gapped on both ends and equipped with a transponder detector. Tradi-

tionally with BDL168/RX4 combinations Detection sections could be combined

inside Transponding Zones. With the BXP88 each of its 8 detection sections

act as both an occupancy and transponding detector, so transponding zones are

incorporated into each detection section.

3.0 Plan Your Feedback System

Before you begin installing BXP88s you should carefully analyze your layout and

what you want to achieve with your feedback system. The key to proper wiring for

occupancy detection/transponding is planning. Your layout will be divided into

Detections sections that can range anywhere from several inches to many feet in

length. This process is custom to each unique layout, with the number and length

of a detection sections varying depending on your layout, train length and the

purpose of the detection/transponding. The BXP88 provides Detection, Tran-

sponding, and Power Management in each of its 8 detection sections, you should

consider if every section on your layout needs these features. Transponding is

often not needed in all detection sections of your layout and other occupancy

only detectors could be used. By using transponding and other types of detection

technologies in tandem, you will be able to get excellent performance and results

at the lowest possible cost.

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.

Signal lights will require information from one or more detection sections in front

and behind of the signal mast to function like the prototype.

Occupancy detection is not only useful, but critical, if operating a hidden staging

area and will let you know which tracks are occupied. In your initial wiring instal-

lation, not all sections have to be connected to BXP88s; they can be connected to

a terminal strip and then to boosters or power management devices. Additional

BXP88s can then be inserted later as needed to further develop your layout.
