SECTION 10 SERIAL REMOTE INTERFACE

10.3 INSTALLATION

Installation of the RS-232 interface is generally performed at the factory. This involves removing the
IEEE-488 interface PCB assembly and rear panel connector/cable and installing the RS-232 interface
assembly and rear panel connector/cable.
INTERFACE PCB DIP Switch S1-5 must be set to ON to indicate that the RS-232 interface has been
installed.

10.4 SETUP

After installing RS-232 interface into the UPC (or after erasing all program memory or after system
RESET), the RS-232 communication parameters must be set (BAUD RATE, PARITY and EOS
Terminator) as follows:
1. Press the fn key, select GENERAL SETUP then UPC STATUS.
2. Press the EDIT key and enter the desired BAUD RATE numerically, selected from the list
above. Then press ENTER.
3. Select the PARITY by pressing the +/- key until the desired selection (NONE, ODD or EVEN) is
shown. Then press ENTER.
4. Select EOS (End Of String) Terminator by pressing the +/- key until the desired selection
(CR/LF, LF or CR) is shown. Then press ENTER.
5. Press STORE.
NOTE: Incorrect communication parameters may result in the UPC displaying a:
PARITY ERROR,
FRAMING ERROR, and/or
OVERRUN ERROR.
Sending a BREAK signal will result in a BREAK RCVD message and will terminate data transmission in
progress from the UPC.

10.5 OPERATION

Operation of the UPC via RS-232 REMOTE interface consists of utilizing the same commands available
for the IEEE-488 interface except as noted below. (see SECTION 5)
NOTE: Normally the UPC is in the LISTENER mode. When the UPC is Queried for information, the UPC
automatically enters the Talker mode until the response data is sent or another command is sent from
the Host.
