IEEE488/RS232, AND LAN
INTERFACE MODULES
The following Control Modules are available:
IEEE488/RS232 CONTROL MODULE is a combined Control Module with all the features of the IEEE488
GPIB Bus and the RS232 Serial Module.
LAN unit transfers 10Base-T LAN data to the RS232 Module.
IEEE488 GPIB FEATURES
This module has the following device subsets.
SH1 - Source Handshake L4 - Listen Functions SR1 - Service Request
AH1 - Acceptor Handshake T6 - Talker Functions
Talk and Listen addresses are the same and set by a 5 position Dip Switch.
Service request operation is programmable and can be used to indicate switch status or command
completion.
In the Listen Mode the Matrix responds to all the Commands after the My Listen Address (MLA) has been
received. The command string must be terminated by either a (CR), (LF) or (END) character.
The Talk Mode is used to return the Status of the Matrix. This is effected by either the My Talk Address
(MTA) or the Serial Poll Enable (SPE).
The basic command strings consist of one or more ASCII characters separated by either a space or
comma and terminated by an end message.
Typical Commands Are:
L - Latch - A specified Module and Switch in a Matrix.
U - Unlatch - A specified Module and Switch in a Matrix.
X - Multiplex - Latches a specified Switch and Clears all others.
C - Clear - Unlatches every switch in the Matrix.
S - Status - The Status of the selected Switches are returned to the Controller.
F - Front Panel - Allows enabling & disabling of front panel controls.
T - Test - Performs a diagnostic test by sequencing through all the switch points at a
predetermined rate.
P - Program - Allows the operator to set up Matrix variables such as size and configuration and
stores them in nonvolatile memory.
APPLICATIONS
BULLETIN AP-5
MANUAL CONTROL OPTION
A Front Panel Manual Control Option allows the Matrix to be controlled from front panel switches. These
controls can be “locked out” by the IEEE488 or RS232 Interface to prevent their use.
A Virtual Manual Control Software enables operators to control the matrix using a Graphical User
Interface.
