Introduction
The STM-4D ARC Solo Digital Temperature Module connects up to four digital temperature sensors to
the ARC Solo remote control system utilizing the rear panel SENSORS port and a supplied 4-way RJ11
Splitter.
Temperature output is user selectable to Fahrenheit or Celsius, based on the user setting in the setup
section of the ARC Solo web page.
Firmware Requirements
The ARC Solo must have firmware 1.0.58 or higher to support the SENSORS One-Wire port for
connecting your digital sensors.
Unpacking
The following items are included with your purchase of STM-4D:
•
TEMP-OUTDOOR Digital Temperature Sensor
•
RJ11 4-way splitter
•
License key to activate the Sensors port on your ARC Solo
Extending Sensor Cables
Sensor cables up to 1000 feet long are supported without measurement degradation. You can extend
any of the sensors with a standard RJ-12 (6-conductor) or RJ-11 (2-conductor) cable. Ensure that the two
center pins (3 and 4) are connected; connection of the remaining pins is not required. Digital sensor
cabling may also be extended using RJ12 couplers, available from Burk Technology
Daisy-Chaining Sensors
Digital sensors may be daisy-chained to allow multiple sensors on a single wire run. See
for wiring details.
