Setup Interface
All parameters on this meter are set through the RS232 interface connection (P3 plug). The RS232 interface allows the instrument to
be set up with either an FC88 hand held communicator or a computer.
The FC88 is powered through the meter and comes with the
serial interface cable. If a computer interface is used, an adapter (RJ to 9-pin PC serial port) is required. The adapter can be obtained
from FCI: Part No. 014108-02.
Using a serial comm/terminal program (e.g., HyperTerminal, TeraTerm, Putty, etc.) configure the PC’s serial port (the one intended to
be connected to the instrument) as listed in the table below.
COM Port Number:
Number of COM port connected to instrument (COM1, COM2, etc.)
Baud Rate:
9600
Number of Bits:
8
Stop Bits:
1
Parity:
None
Flow Control:
None
Terminal Emulation:
VT100
After configuring the serial port (and making the PC-to-instrument connections) start a communications session with the applicable se-
rial port. Enter any of the meter’s single letter commands in the program’s terminal window to execute a function. See “Table 5. ST75/
ST75V List of Single Letter Commands” on page 23 (Appendix B) for the complete command list.
An additional command line interface (CLI) is available through the RS232 port. This interface is accessed with the “Y” command
using a computer or FC88. The command line password is “357”. See “Table 6. ST75/ST75V List of CLI Commands” on page 23
(Appendix B) for command line details.
