1.0 Introduction

The BDL16 uses digital signal processing (DSP) to give you occupancy detec-

tion for 16 detection sections on your layout. The BDL16 can also host

transponder detectors to let you implement Digitrax transponding. The BDL16

reports detection section occupancy and transponder location information to the

system via its LocoNet connection. You can also install LEDs in an occupancy

display panel to report detection section occupancy and transponder location.

The BDL16 is split into 4 zones, A through D, each with 4 detection sections,

for a total of 16 detection sections. Each BDL16 zone can be run from a dif-

ferent booster.

On your Digitrax system, the BDL16 automatically detects the LocoNet con-

figuration it finds and initializes itself accordingly. This automatic detection

also lets BDL16's be used for occupancy detection on DCC systems without a

Digitrax compatible LocoNet command station.

The BDL16 can operate with no connection to LocoNet, using only the

RailSync DCC signal from any Digitrax compatible DCC system, and report-

ing detection information via optional LED outputs.

2.0 Terminology

Following are some terms you might find useful as you work with the BDL16.

Direct home wiring is a layout wiring method where each power district and

its booster is electrically isolated. The track within each power district uses a

"common return" wiring method for occupancy detection and/or power man-

agement. Direct home wiring is the wiring method recommended by Digitrax

for safety reasons & also because it makes detection work more prototypically.

Power district is the power wiring, components and equipment attached to that

wiring, driven by a single properly isolated booster. Power districts are double

gapped on both ends. BDL16 is used to set up detection sections within one or

more power districts.

Power sub-district is the wiring, components and equipment that are con-

trolled from both power bus wires by their own power management device, for

example a reversing section controlled by an automated reversing device like

the PM4. Power sub-districts are gapped on both ends.

Detection common is the common return used within a properly electrically

isolated power district for implementing occupancy detection.

Security element is the plant, including track, associated with any reporting,

interlocking and/or signaling for that track section.

Whole layout common rail is a method of wiring layouts where power dis-

tricts and their boosters are connected electrically by a common rail or com-

mon power bus return wire. This method is traditionally used for convention-

ally controlled layouts. The track feeds for one rail are connected together to

one output of the power pack. The other rail is gapped and the track feeds are

connected to the power pack through block control switches. Whole layout

common rail wiring has a disadvantage when it comes to detection systems

because detectors are not able to independently monitor whether zone power is

on or off. There is no way to tell whether occupancy detection is actually

working in any given detection section.

Detection Section is a section of track gapped on one or both rails and con-

nected to an occupancy detector so that the detector can sense the presence of a

loco (or other specially equipped cars) in that section of track.

Occupancy detector is a device that senses the presence of a locomotive (or

other specially equipped cars) in a section of track that is set up for occupancy

detection. Occupancy detectors also provide feedback to indicate occupancy.

This feedback may be in the form of a lamp on a control panel or it may be a

feedback message sent to the system that can be used by other layout devices.

Also called a block occupancy detector on conventional layouts. Detectors are

not covered by the DCC Standards or Recommended Practices.

Transponder is an electronic device with a transponder address that is

installed in rolling stock. Transponders provide information to transponder

detectors installed on the layout. This lets the system determine in which

detection section the transponder is currently located. Transponders are includ-

ed in many Digitrax premium decoders. TD1 (transponder) & TL1 (transpon-

der with light output) are available as separate units that can be added to locos

with existing decoders or 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 installed in a detection section

on the layout that receives the information broadcast from a transponder. The

transponder detector sends feedback to the system that lets it determine the

detection section location of any given transponder at any time. RX4

Transponder detectors are hosted by the BDL16 and upgrade 4 detection zones

of the BDL16 to be transponder detection zones. In this case, each transpond-

ing zone encompasses 4 detection zones.

The BDL16 is divided into four Zones. Each Zone supports 4 detection sec-

tions and each zone can be run from a different booster.
