UPS Communications Interface Port

In addition to configuring the UPS for specific communication options,

you must also ensure proper use of the serial port when connecting the

UPS to your network or monitoring equipment.

CAUTION

The serialport LANcontactsare transistorsand are ratedat a maximumcurrent of

50 mA and a maximumof +40 Vdc.Do notexceedthese ratings orapplyany

negative voltageor ACvoltageto these contacts;otherwise,damage mayoccur to

yourUPS.

Use only the pins specified for your communications configuration. The

use of any additional pins for any of the following interfaces can cause

interference with system communications.

Even though your network uses the specified signal lines, the pins

assigned to these signals at the network end of the cable may vary with

those of the UPS serial port. The connector body and style may vary as

well.

NOTE Standard,pin-for-pincablesmaynot workcorrectly.Consultyour network

softwareor server manualsfor system shutdown pin assignments.

The UPS serial port complies with EIA RS-232 standards. RS-232

specifies a maximum cable length of 50 ft (15m). See Figure 16 for the

location of the serial port.
