SECTION 10 SERIAL REMOTE INTERFACE

10.6 TESTING THE RS-232 REMOTE INTERFACE
1. Connect the UPC RS-232 serial interface to a DTE serial port of a PC using a DB-25 cable.
Most 25 pin connectors on PC's are DTE type. The UPC is a DCE type and must connect to
a DTE port. If using a 9 pin connector on the PC, verify the pinouts of the cable match the
UPC to the PC correctly.
2. Configure the PC Baud Rate to 19200 or 9600 Baud, No Parity, 8 Data bits, 1 stop, 1 start
bit using a terminal emulation program. Ensure the UPC is configured the same (see
paragraph 10.3 of this manual for setup). Leave the EOS set to CR/LF.
3. Enter the UPC STATUS display of the UPC (fn,3,3), do NOT press EDIT this time. See
paragraph 10.4.1 for info on the COMMUNICATION MONITORING AID.
4 Send Executable commands from the PC such as SYST:BEEP, VOLTS 100, FREQ 50, and
verify that the UPC responds correctly.
5. Send Query commands from the PC such as *IDN?, FETCH:VOLT1?, and verify that the PC
receives correct data from the UPC after each Query command is sent. No other operation
is needed to cause the UPC to send the response data.
