2.6 RS-232 Communication Options
2. FEATURES
RS–232 Connector
The connection/specifications for the RS–232 serial port vary depending
on the installed interface device ( i.e., SID or IID option).
Rear Panel RS–232 Port
The RS–232 port on the CFR follows the Data Communication Equipment
(DCE) pinout. To connect this port to a terminal or a host computer (which uses a
DTE pinout) you need a standard off-the-shelf ("straight-through") RS–232 cable.
Depending on your computer, you need a “
9 to 9 serial cable” or a “9 to 25 serial
cable”. However, if you decide to make you own cable, see Fig. 9. The cable
shown works with both SID and IID. If your CFR has a SID interface, then you do
not have to wire up the RTS and CTS signals. For SID equipped units, the DE9-
DB25 cable can also be used with an external modem.

5.12 Parameter Dump Command (Function 0)
Parameter Dump Command (Function 0)
Function ‘0’ displays all UPS parameters in the following format:
#####,###.#,#####,#####,##.##,###.#,#####,###.#,#####,###.#,#####,#####,##.##,
###.#,###.#,###.#,xxxxx,#####,#####,#####,#,##,##,##,##,##,##,##,##,
###############,############ <CR> <LF>
Where ‘#’ indicates a digit or a blank character and ‘x’ represents a
letter. The string is terminated by a Carriage Return and a Line Feed.
Parameters are separated by a comma (‘,’). Above is the exact format for the
SID option; IID option has slightly different format (less blank characters).
This command lists the CFR parameters in the following order:
1. Input Voltage 17. Charger Status
2. Input Current 18. Battery Temperature
3. Input VA 19. Efficiency
4. Input Watts 20. Capacity
5. Input Power Factor 21. Run Time Remaining
6. Input Frequency 22. Mode Data
7. Output Voltage #1 23. Input Alarms #1
8. Output Current #1 24. Input Alarms #2
9. Output Voltage #2 25. Battery Alarms
10. Output Current #2 26. Output Alarms
11. Output Watts 27. Environmental Alarms
12. Output VA 28. Inverter Alarms
13. Output Power Factor 29. System Alarms
14. Output Frequency 30. IID/Micro Board Serial #
15. Battery Voltage 31. Unit model - config. version
16. Battery Current

In the above example, 114 represents the Input Voltage, 1.22
represents the Input Current, 133 represents the Input VA, etc.
