3. Pin Assignment:
1) PIN 2: TXD <Transmitting Data>
2) PIN 3: RXD <Receiving Data>
3) PIN 5: GND <Signal Ground>

4.4 Parallel Ports

The two parallel ports are for UPS parallel communication. UPSs (at maximum four) with the same
capacity, voltage and frequency can be coupled via the provided parallel cable to run in parallel
mode. To enhance parallel reliability, please adopt Daisy Chain method (see Figure 5-10 & Figure
5-11) to execute parallel configuration.

4.5 External Battery Temperature Ports

A. The external battery temperature ports are used for detecting the connected external battery
cabinet's temperature. You need to purchase the optional external battery cabinet temperature
detection cable to do that. Please NOTE that this function is realized by Port 1, and Port 2 is
reserved.
B. You can also purchase the Mini SNMP card (IPv6) and the EnviroProbe 1000 to detect the
external battery cabinet's temperature.
