Chapter 6 Computer Interface

6-1

6.0 Introduction


The computer interface capabilities of the SQS-242 program allow operation from an
external computer via Ethernet or RS-232 serial communications. The active process
can be selected, process parameters read or changed, operation controlled, and data
collected.

Parameters may be read (Query commands) while the process is running, but can only
be changed (Update commands) while the process is stopped. Changes to the
“structure” of a process (e.g. add or delete layers) are not allowed from the computer
interface.

6.1 Serial Interface


Connect a serial cable from the SID-242 serial port to a computer serial port. The cable
required is a DB9 female to female with pins 2 and 3 crossed, commonly referred to as
a null modem cable.

In the SQS-242 program select the Edit, System menu, then the Comm tab. Set the
Comm Port to match the serial port the cable is connected to on the SID-242. Set the
baud rate to match the baud rate of the host computer that will be connected to the
SID-242. Communications format is No Parity, 8 bits, 1 stop bit.

6.2 Ethernet Interface


Connect a cable from the Ethernet card to your Ethernet network. In the SQS-242
program select the Edit, System menu, then the Comm tab. Set the Ethernet port to
1001, and the Ethernet name to the Network name, or IP Address of the computer you
wish to communicate with.
