SECTION 10
RS-232 SERIAL REMOTE INTERFACE OPTION
10 RS-232 SERIAL REMOTE INTERFACE OPTION
This section describes using the optional RS-232 (Serial) REMOTE interface of the UPC. This section is
intended to be used in conjunction with section 5 of this Operation Manual.
10.1 GENERAL
The RS-232 REMOTE interface may replace the IEEE-488 (GPIB) interface as an option in the UPC.
Check the connector label at the rear of the unit to determine which interface is installed.
10.2 SERIAL PORT SPECIFICATIONS
The RS-232 REMOTE interface of the UPC is compatible with the ANSI/IEEE-488.2, SCPI and RS-232C
standards. It loosely adheres to the RS-232C standard as some interfacing requirements of that
standard are not necessary.
This REMOTE interface of the UPC has the following communication characteristics:
1. Selectable
BAUD RATES of: 38400 BAUD
19200 BAUD (default)
9600 BAUD
4800 BAUD
2400 BAUD
1200 BAUD
300 BAUD
2. Selectable
PARITY of ODD, EVEN or NONE (default).
3. Selectable
EOS (End Of String) Terminator CR, LF or CR/LF (default): Sets the EOS sent from
the UPC. The UPC accepts any of the above combinations when receiving.
4.
8 Data bits, 1 Start bit, 1 Stop bit.
5. HARDWIRE HANDSHAKE only, (X-ON/X-OFF not available).
The Serial Remote interface of the UPC has the following Handshake characteristics:
A. Operation is HALF-DUPLEX (per IEEE-488.2).
B. The UPC operates as a DCE.
C. DTR from the HOST (DTE) is ignored.
D. DSR and DCD from the UPC is maintained in a TRUE state.
E. CTS from the UPC is used to signal the HOST that the HOST may send data.
F. RTS from the HOST is used to signal the UPC that the UPC may send data.
Refer to section 10.6 below for Pinouts and Signal names.
