The BDL162 is ready to set up four transponding zones with the addition of an

RX4 Transponder Detector. Transponding allows two-way communication with

rolling stock equipped with a transponding decoder or a stand alone transponder.

Many of the Digitrax Premium and FX

You may need to set the decoder CV61 value to enable transponding. The set up

for transponding operation is covered in the RX4 Installation Manual and in the

Digitrax Decoder Manual.

Transponding allows you to keep track of where individual transponder-

equipped rolling stock is located on your layout. Your dispatcher can keep bet-

ter track of trains, knowing exactly where each train is located. Additional

applications include surround sound specific for each loco, automated train

control, and remote layout operation. Transponding also allows Operations

Mode Read Back of decoder CVs while operating your trains on your layout

providing you additional control over your locomotives.

If you are planning to use Digitrax Transponding with your BDL162 please

allow space to install the RX4 Transponder Receiver as shown in Figure 3.

Additional information about transponding can be found in the RX4 instruction

manual and on the web in the Digitrax Application Notes and Technical

Information Section/Advanced Transponding Application Note.

13.1 Packet Reception

Be sure the green ID LED is ON & is "winking" off about every 2 seconds.

This means that correctly formatted DCC packets are being decoded from the

left most (Railsync) pin of the RJ12 LocoNet socket. For DCC detection, the

same DCC packet signal that drives the booster must be connected to the RJ12

socket's left most pin. If you are using LocoNet and you do not see the green

LED blinking pattern described, check to be sure that the system is powered up

and your LocoNet cable connections are good. You can use your LT-1 to test

the LocoNet cables if you suspect there is a problem with them. If the green

LED on the BDL162 is not lit, check the external power connections.

13.2 Mode Indication

The winking on the green ID LED indicates the primary BDL162 mode. A sin-

gle wink indicates standard Digitrax compatible Direct Home track wiring and

detection logic will be used, a double wink indicates Common Rail wiring and

detection logic is to be used. For Common Rail, all 4 BDL162 zone connec-

tions must be made to the System Common ground point. Be sure the BDL162

configuration is appropriate for your usage.

13.3 Occupancy Debug

Use the LT5 provided with your BDL162 as described in Section 11.2. You can

also build a simple LED display debugger as follows. Use a 10 pin plug and

cable such as DigiKey (1-800-DigiKey) part number M1AXA-1036R-ND that

decoders are transponder-equipped.

will plug into one of the 4 occupancy LED headers on the BDL162 and solder

LEDs to the wires to create an array of LEDs (see Figure 6). By plugging this

display array into one of the 4 occupancy LED headers (Figure 5, marked

A,B,C & D), you can see the state of the zone and occupancies for that header.

This allows you to easily check the zone sensitivity (typically 22 Kohms to

give detection). This also aids in the determination of detection number and

activity for a track detection section. Many detection problems are related to

wiring problems or poor connections to the detection section rather than to the

actual BDL162. By using the display array, you can eliminate the wiring issues

from the equation and be sure that the BDL162 is set up correctly.

Remember, if the zone power is OFF, the occupancy LEDs should be set up so

that they will be on to be sure that signaling systems or a CTC/dispatcher will

see the detection section in its most restricted aspect.

13.4 LocoNet Debug

If you are using LocoNet for reporting, be sure that the configuration is correct

for your usage. In normal operations the red "option" LED will blink ON

briefly when valid LocoNet messages are seen confirming a good LocoNet net-

work connection.

13.5 Analog Locomotives

The motor inductance of analog locomotives may in some installations cause

cross talk among the BDL162 detection sections. The addition of a 220ohm,

3 watt, wire wound resistor between the booster track terminals (Rail A and

Rail B on Digitrax boosters) will typically reduce the effect of this cross talk.

Simply use a leaded resistor as a jumper between the booster's two track termi-

nals.

Radio or TV Interference: (this information is MANDATED by the FCC) This

equipment has been tested and found to comply with the limits for a Class B

digital device, pursuant to part 15 of the FCC rules. These limits are designed

to provide reasonable protection against harmful interference when the equip-

ment is operated in a residential environment. This equipment generates, uses

and can radiate radio frequency energy and, if not installed and used in accor-

dance with the instruction manual, may cause harmful interference to radio

communications. However, there is no guarantee that interference will not

occur in a particular installation. If this equipment does cause harmful interfer-

ence to radio or television reception, which can be determined by turning the

equipment off and on, the user is encouraged to try to correct the interference

by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and the receiver.
