Operation

3.2.15Communication Interfaces

Your Liebert Series 610 UPS includes the following communication ports:

•Worldwide reporting to a remote terminal through a modem

•Reporting to a local terminal (no modem required)

•Reporting to a local monitor only

•Site reporting to Liebert SiteScan or other central monitoring system

•Reporting through an SNMP interface to a building management or network management system

•Selected alarm messages to a Liebert Remote Monitor Panel and to contact closures for customer use

All external communication devices, including the modem, are optional equipment. Connections to communication ports are made by wiring cables to terminal boards at the SCC. Connection points are shown on the Control Wiring Interconnect Diagram in the installation manual. Contact Liebert Glo- bal Services for assistance when attaching an external device to your UPS system.

Any terminal that accepts the standard 7-bit ASCII codes and conforms to the data link requirements can be used to interface with the Series 610 UPS. If a printer is used, the terminal must support it. The UPS does not send or receive any printer control commands.

Data link requirements are:

•Asynchronous RS-232 communication

•Terminals may be configured as DTE or DCE

•Baud Rate:

Modem: 1200 or 2400

Terminal: 2400 only

•Data Bits: 8

•Stop Bits: 1

•Parity: None

•Handshaking: Not required

•Full Duplex

Worldwide Reporting

The Series 610 transmits UPS system status and history information to a remote terminal in RS-232 format through a PC-compatible modem.

Auto-Dial

The Series 610 UPS communication program will automatically dial a pre-programmed (customer- selected) phone number when specified alarm conditions occur. The auto-dial phone number, an alter- nate number and the modem baud rate are programmed by using the SCC System Configuration screen. The alarm messages that initiate an auto-dial call are identified in Table 9.

When the auto-dial function is initiated, automatic dial attempts to the first phone number are made at periodic intervals for 30 minutes. If unanswered, the system rolls over to the second number and repeats calling until connection is made or returns to first phone number after 30 minutes.

Once a connection is made to a terminal, the system transmits the information on the Present Status Report screen, then hangs up. The Present Status Report includes the UPS system identification number, date, time, alarm messages and metered parameter indications.

Requesting Information

If your Series 610 is equipped with a modem and telephone line, you can call the UPS and receive sys- tem status and historical information on discharge events. You can place the call from either a remote terminal or a personal computer with a communications program.

Follow the instructions for your terminal or your communications program to call the UPS. When you make connection, the UPS will send you the greeting: “Hello, you are connected to a Series 610.” At this point, the UPS will respond to your specific requests for information, according to Table 11.
