Product Overview
An AMR sits between an ARC156 controller network and a BACnet MS/TP segment and routes traffic across, so older ARCNET controllers and newer MS/TP devices work in one system. The ARC156 side runs ARCNET at 156 kbps, and the MS/TP side is two-wire EIA-485 with up to 32 devices on the segment.

- ARC156 port with Net+, Net- and Shield terminals
- MSTP port with Net+, Net-, two n/c and Shield terminals, plus a 2W / 4W jumper
- MS/TP baud settings marked 9600, 19.2k, 38.4k and 76.8k
- Two rotary ARC156 Addr switches, 10's and 1's
- Rnet terminal (Gnd, Rnet+, Rnet-, +12V) and Local Access port (Gnd, Rnet+, Rnet-, +12V Sense)
- Power 24 Vac plus or minus 10 percent, 50-60 Hz, 10 VA, Class 2, or 26 Vdc at 5 W
- CR2032 lithium cell keeps time and editable properties through a power outage
- 4.0 in wide by 5.0 in high, with 5-9/16 in between mounting slot centerlines
- Rated 0 to 130 F, 10 to 90 percent relative humidity, non-condensing

Applications
- Adding BACnet MS/TP devices to an existing ARC156 controller network
- Replacing a failed AMR in an HVAC control panel without rewiring the trunk
- Holding a spare router for a campus building automation system
Frequently Asked Questions
Does it run on 24 Vac?
Yes. The label reads Class 2, 24Vac, 50-60Hz, 10VA, 0.42A, landed on the Gnd and Hot terminals.
Can the MS/TP side run at 76.8k?
Yes. The MSTP Baud settings are marked 9600, 19.2k, 38.4k and 76.8k.
Does a spare memory battery come with it?
Yes. An extra memory battery comes with each module.
Is a transformer or mounting hardware included?
Not included.
Will it take the place of a failed AMR already wired in a panel?
Yes. The label reads AMR, BACnet ARC156 to MS/TP Router, and the terminals carry the same names, ARC156 Net+, Net-, Shield and MSTP Net+, Net-, Shield, so the existing wires land where they were. Set the ARC156 Addr switches and baud to match the old unit. Flat-rate shipping in the lower 48, and orders over the free-shipping line ship free.
The label names two networks and one job between them. Set the address dials to match the old unit, land the wires, and both halves of the building can share a trunk again.
