tor LocoNet cable), position the LocoNet termination jumper, locat-

ed behind the RJ12 sockets, across both pins. If the PM42 is con-

nected to a working LocoNet, you do not need to use the LocoNet

termination jumper.

3. Press and hold the "ID" button behind the green LED for about 1 sec-

ond. The green "ID" LED will blink when the button is released.

This indicates that the PM42 is in board address setting mode.

4. Enter switch control mode on the throttle according to the throttle's

instructions. Select the switch address that corresponds to the board

address you want to assign to the PM42. Press the "c" button to

issue a "closed" command. This will set the board address the same

number as the switch address you selected. The green "ID" LED will

change to steady green indicating PM42 Power ON and that board

address setting mode is complete. Be sure to reconnect to LocoNet

and return the LocoNet termination jumper to its original position.

5. To exit board address setting mode with no changes, press the "ID"

button a second time and hold it for about 1 second. Be sure to

reconnect to LocoNet and if you use the LocoNet termination

jumper, move it back to its original position.

7.0 Troubleshooting

Short circuit is indicated when lights are turned on in locos or rolling

stock.

Because turning on incandescent lamps creates a brief current spike that

may be detected as a short circuit by the system, you need to

decrease your short circuit detection sensitivity. See Table IV for

appropriate settings for each PM42 section.

DCC locos do not resume operation immediately after short circuit shut-

down.

1. Because of the differences in the amount of energy stored by different

decoders, you may need to increase the sensitivity of your short cir-

cuit detection. See Table IV for appropriate settings for each PM42

section.

2. Set the decoder's CVs for Accel and Decel to 0. This will allow the

decoders to start the loco moving immediately when power is

restored to the track. Use your Digitrax throttle to simulate accelera-

tion and deceleration instead.
