8.7 Remote display

8.7.1 Introduction

The remote display unit provides the Silcon DP300E series with the possibility to

display condition data at remote sites of up to 25 meters away from the Silcon

DP300E unit. For extension of communication distance, see section 8.7.1.1 below.

The remote display can easily be connected to the Silcon DP300E series via the serial

communication ports on the communication interface.

To obtain a transmission distance of 3.2 km the normal RS232C signal levels of the

serial in/out port must be converted to a 20mA current loop. The RS232C/20mA

converter must be placed outside the Silcon DP300E cubicle.

8.7.1.1 Extension of communication distance for remote display

The remote display communicates with the UPS through a 3 wire RS232 interface.

The remote display is a DTE (Data Terminal Equipment) employing a SUB-D 9 pole

female connector. The communication speed is 9,600 bps.

The communication distance is rather limited, see Table I. If a longer distance is

necessary or if the communication cable goes through magnetic noisy areas, it is

necessary to insert converters. Table 1 gives examples of three ways of increasing the

communication distance. All converters must be locally purchased.
