MODBUS END JUMPER (J1):
If the UPS is connected at
the end of the bus line ; the
jumper should be configured as
described.
The RS485 differential line consists of three pins:
• A is inverting pin (TxD-/RxD-)
• B is non-inverting pin (TxD+/RxD+)
• Middle Pin is reference pin (optional GND)
Middle Pin is the reference potential used by the
transceiver to measure the A and B voltages.
The B line is positive (compared to A) when the line is
idle.

RS485
RS485 with Modbus protocol is used in a wide range of automation systems for Industrial Process
monitoring or for Building Management Systems. This communication link allows monitoring UPS status
and measurements with such systems.
