A cost effective way to add automatic reversing to one section of your DCC layout.

Features

• Cost effective automatic reversing for one reversing section or subdistrict
• User selectable trip current lets you adjust the AR1 to work with any scale or equipment on your layout
• Auto-Reversing manages polarity mismatches on the reversing track section without manually throwing electrical toggle switches or adding another booster
• 8 amp peak, 6 amp continuous Auto-reversing control for a single reversing district
• Simple to wire 4 wire hookup, no locomotive wiring required
• No external power required, runs off track power
• AR1 operates with or without LocoNet, so it is compatible with all DCC systems

Alternatives to AR1 for Automatic Reversing on your layout:

1. Use a double pole, double throw switch to manually allow for reversing
2. Use one Digitrax booster set for automatic reversing and another set for normal operation
3. Use a PM42 Quad Power Manager to handle 4 power sub-districts. You can set these up to be automatic reversing or power managers to prevent short circuits from shutting down your layout

PM42 Quad Power Manager lets you use a single booster and divide its output into 4 power sub-districts for automatic reversing or to improve operation by preempting booster shutdown when a short circuit is detected by the PM42.

Features

• Cost effective power management for 4 power sub-districts
• Short circuit management or auto-reversing for each sub-district
• Increases layout reliability by preempting booster shutdown, minimizes downtime by automatically restarting once a short is cleared
• User selectable short circuit detection sensitivity to optimize operation with other layout equipment
• Auto-Reversing manages polarity mismatches on reversing track sections
• Auto-Reversing is automatic, no need for toggle switches or additional boosters
• PM42 connects to LocoNet to transmit information to your system
• No locomotive wiring modifications needed

Note: External power supply is needed. PS14 (sold separately) or equivalent is recommended.

Current PM4 users can upgrade their units for the new features of the PM42 by changing the chip on the board and re-programming the PM42 for their operation.
