APPENDIX I: REMOTE COMMANDS AND QUERIES
15.1
OPENING RS-232 COM MUNICATION INTERFACE
The CS130
B’s USB port implements the USB Test and Measurement class (USBTMC), making it
directly compatible with National Instruments’ LabVIEW programming system. It provides a robus t
way to send messages to the CS130B. However, RS232 continues to be an extremely simple
communications bus, once it is configured correctly.
Commands and Queries may be sent to the CS130
B’s RS-232 port using HyperTerminal, PuTTY,
YAT,
Newport’s MonoTerm, or other similar terminal-emulation programs. Connect a standard 9-
pin PC serial port to the CS130B using a straight-through (not null modem) cable. Once the
terminal program is open and running, select the connected COM port and configure it ac cording
to the following settings:
Baud Rate: 9600
Data Bits: 8
Parity: None
Stop Bits: 1
Flow Control: None
The CS130B requires all Statements to be terminated by a carriage return followed by a linefeed.
Configure the terminal emulator to send a carriage return and line feed (CR-LF) as its terminat or
1
.
All responses from the CS130B end with a carriage return followed by a linefeed.
When shipped from the factory, the CS130B echoes each RS-232 character as it receives it. This
feature can be turned off or on using the “Echo” command (see the Command Reference). The
echo can be handy when troubleshooting a serial connection, but it may be troublesome when
developing a test program.
Note: the RS-232, USB, and Hand Controller ports are all active at all times. There are times when
this can be useful but it’s important to recognize the possibility that commands rec eived on one
port could override those from another.

Some terminal
emulators call the terminator the “EOL (end of line) sequence”.
