6.6Remote Display
With the remote display unit data may be displayed at distances of up to 25 m from UPS. For extended communication distance, see section below.
Remote display may easily be connected to UPS via one of the two serial communication ports on the communication interface board.
To obtain a transmission distance of up to 3.2 km normal RS232C signal levels must be converted to a long distance communication standard. The converter must be placed outside the UPS cabinet.
6.6.1 Extension of Remote Display Communication Distance
Remote display communicates with the UPS through a
For communication distances, see Table 1. Insert converters if longer distances are necessary, or if communication cables are led through magnetically noisy areas. Converters must comply with local regulations

Two converter boxes are required for a communication distance extension: One
box near the UPS for the conversion from RS232C to a long distance communication standard, and another box at the other end to convert back to RS232C, which is to be connected to the Remote Display. The converter provides optical signal insulation. Both converter boxes must be supplied by an uninterruptible power source.
