The RS485_R DIP switch is used to enable a build-out resistor so that the ambient T/H
sensor can communicate with the controller. If there are no more than four ambient T/H
sensors on the bus, the RS485_R DIP switch does not need to be set. If there are more than
four, ip the RS485_R DIP switch of the ambient T/H sensor furthest from the UPS to ON.
● DIP switch settings on ambient T/H sensors
Each ambient T/H sensor has a unique DIP switch address, ranging from 32 to 44.
A DIP switch has six binary toggle switches. The bit on the leftmost is the most
signicant bit, and the bit on the rightmost is the least signicant bit. Bit 1
indicates ON, and bit 0 indicates OFF.

● DIP switch settings on battery temperature sensors
When an ambient T/H sensor is used as a battery temperature sensor, set the DIP
switch to a value in the range of 16 to 28 to monitor the battery temperature.
