Use the following Modem Mode configuration screen to control modem operations:

Modem Mode: IN 1-(000) 000-0000 Site ID:

Your Location

The options of the first line of this screen are IN, OUT, BOTH, or OFF. IN calls are from a remote terminal operator to the UPS. OUT calls are alarms reported from the UPS to a selected phone number with a modem attached. BOTH enables both IN and OUT calls. OFF disables modem connections, but a directly connected computer terminal may still be used.

The second line allows entry of the phone number the UPS calls when alarms occur. Remember to include a 9 or other characters if required. When initiating a call, the UPS makes up to 3 attempts to connect, spaced 45 to 90 seconds apart, before giving up.

Enter the Site ID on the fourth line. The UPS includes Site ID in OUT messages to distinguish multiple UPS’s programmed to call the same phone number. Use up to 16 characters (letters, numbers, and spaces) for the Site ID.

For terminal IN calls, the screen displays ”Press <SPACE BAR> to enter terminal mode...”. Use the keyboard to get information from the UPS or to perform remote ON, OFF, or Transfer as described above. If no keys are pressed for 6 minutes, the UPS hangs up.

For UPS OUT calls, the receiving terminal beeps and displays the message ”Press any key to enter terminal mode...”. If no key is pressed within 10 seconds, the terminal displays present alarm condition(s) information along with the Site ID. The time of each alarm displays to the nearest tenth of a second.

The event code(s) alarm description also display. Then the message ”Press any key to enter terminal mode...” displays again. Press a key to enter terminal mode, and show the LCD display as described earlier in Terminal Operation. If no keys are pressed for 45 seconds, the UPS hangs up.

RS-232 with User-Configurable Relays - VCR232C

This provides user-selected contact closure output on the RS-232 board, for use with remote monitoring devices. The board also includes two relays. Program these relays as NO or NC to activate upon any combination of these alarms:

UPS on Battery

Low Battery

UPS on Bypass

Battery Test Fail

UPS Fail Overload

These relay outputs use an RJ45 connector. Connector and 25’ pigtail supplied. Program the relays via the UPS LCD display on the front panel.

Cables

∙An optional factory-assembled 6-foot cable enables connection to a modem.

∙A factory-assembled splitter cable enables connection to a modem (or terminal) and a Computer/LAN interface.

∙To assemble a customer supplied cable, refer to the following instructions and Figure #5:

∙For a modem cable, connect to pins 2, 3, 7, 8, 20, and

22.Connect Pin 2 on one end to pin 3 on the other end (this applies to two wires). All other connections are straight through.

For a terminal cable (direct connection, no modem) connect to pins 2, 3, and 7. All connections are straight through.
