Communication Interface; Rs232 Serial Interface; Ieee-488 Interface; Section 8: Communication Interface - Laversab 6300 User Manual

The model 6300 is capable of communicating with a remotely located computer via the RS232
serial interface. Using this interface it is possible to perform all functions that are available on
the front panel.

8.1 RS232 SERIAL INTERFACE

The serial interface is a three wire interface using the signals RX, TX and GND. Each byte of
data is sent in ASCII format using 8 bits per byte, with 1 stop bit, no parity at 9600 baud.
The pin-out of the interface is as follows:
Pin 2 - Transmit (TX)
Pin 3 - Receive (RX)
Pin 5 - Signal ground (GND)
The baud rate, parity, bits per byte, and number of stop bits cannot be altered and is set to
9600, No parity, 8 bits and 1 stop bit respectively.

8.2 IEEE-488 INTERFACE

This interface is accessible through the 24-pin parallel connector under the "Interface
Connectors" cover on the top panel. This interface supports the following IEEE-488 functions.
SH1
AH1
T2
L2
SR1
DC1
The IEEE-488 address of the 6300 can be changed using Function '0' as described in Section
3.5.0.
