into one of the 4 occupancy LED headers, you can see the state of the zone and

occupancies for that header. This allows you to easily check the zone sensitivi-

ty (typically 22K ohms 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 BDL16. By using the display array, you can

eliminate the wiring issues from the equation and be sure that the BDL 16 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.

11.4 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.

11.5 Analog Locomotives

The motor inductance of analog locomotives may in some installations cause

cross talk among the BDL16 detection sections. The addition of a 220ohm

3watt power 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

terminals.

13.0 FCC Information

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

ment 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 equipment is operated in a residential

environment. This equipment generates, uses and can radiate radio frequency energy

and, if not installed and used in accordance with the instruction manual, may cause

harmful interference to radio communications. However, there is no guarantee that inter-

ference will not occur in a particular installation. If this equipment does cause harmful

interference 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.

-Connect the equipment into an outlet on a circuit different form that

to which the receiver is connected.

-Consult the dealer or an experienced radio/TV technician for help.

Note that any modifications to the equipment not expressly approved by Digitrax voids

the user's authority to operate under and be in compliance with CFR 47 rules, as

administered by the Federal Communication Commission. Digitrax believes any

conscientiously installed equipment following guidelines in this manual would be

unlikely to experience RFI problems.
