DELAY t Force a minimum delay of t milliseconds
between two instructions
RESET Open all switches on all modules
VIEW? a View status of device a
CHAN a,c Select channel c on multiplexer a
Automatically clears previous channel (if
set) before selecting new channel.
CHAN a,c,s Multi-channel selection argument s
allows
opening/closing of any combination
of channels.
Common
The common signal(s) are brought out from the module onto the
Front panel connectors. This has the additional features of keeping
the signal(s) isolated, improving crosstalk, DC leakage and low
thermal emf performance.
Creating Larger Multiplexers
When more than one module is used to make up a multiplexer, ie.
where ve modules are used to make up a 80 channel multiplexer
– then all multiplexer units must have the same internal address,
the location of each module within the multiplexer is given by its
own bank address. Bank addresses must start at 0 and should be
contiguous.
If there is a problem with any of the modules used to make up a
large multiplexer then an error will be detected (use the REPORT?
query to discover the cause).
Additional Notes
Mercury wetted reed relay modules must always be mounted to
within 30° of vertical.

FUNCTIONAL DESCRIPTION
A functional block diagram is provided in Figure 2.1. The Matrix Module is powered by +12V relay and +5V logic
supplies via the Driver PCB backplane connector J1, and +5V and +12V via the Relay PCB backplane connector J2.
The module comprises a Driver PCB feeding the Relay PCB with serial data via its control logic IC’s. The interface
to the user test equipment is via the front panel mounted connectors.
The Relay PCB is populated with electro-mechanical relays to provide an 8 or 16 Channel Multiplexer with various
Pole congurations. An ‘Active’ LED on the front panel indicates when a relay is ‘closed’ via control signals from
relay drivers U1 and U2. Relay switching is determined by operator programming.
Modules can be coupled together to provide an even larger multiplexer as required.

SECTION 3 - INSTALLATION
!
MODULE INSTALLATION
The module should be installed in accordance with the following procedure:
1. Ensure that the system is turned OFF but still connected to mains so that it remains grounded.
2. If the module has address switches ensure they are set to the appropriate position. (See Section 4).
Note individual modules are not sent out with a system drawing detailing their address.
3. Choose an appropriate slot in the rack and remove the blanking plate (if tted).
(See the Pickering 10-910M IEEE-488 GPIB System 10/20 Ancillaries manual for further details).
(When tted, additional modules will be automatically recognised by the interface card. See Figure 3.1).
4. If necessary t the module guide rails as supplied with the module to both the top and bottom of the chassis
in that slot position. One guide rail slot should be to the left of the connector as shown in Figure 3.2.
5. Align the module with the backplane and screw holes at the front of the chassis.
Hold the handle whilst slowly sliding the module into the card guides until the module seats rmly into the
backplane. See Figure 3.3. The front panel of the module should be ush with the front or rear panel of the
chassis.
6. Screw the front panel of the module to the chassis front panel mounting rails.
7. Ensure all necessary modules including the power supply are tted to the rack and other slots blanked off
before powering up.
To achieve the correct initialisation of the sytem, ensure any slave chassis are powered up before the master
chassis.

Selecting the Module Address
Choose a primary device address (from 0 - 30) using the address select switch SW1 on the driver card.
Each module must have a different address to the existing modules in the rack or system.
The primary address selected in Figure 4.1 is 22 (16 + 4 + 2 = 22).

Figure 4.2 - Addressing
When more than one module is used to make up a large matrix (see Page 1.1); ie. where six modules are used to
make up a 24x16 matrix, then all matrix units must have the same primary address. The location of each module
within the matrix is given by its bank address. The matrix bank address is composed of two x and y components,
(see Figure 4.2) and these determine the individual matrix module positions within the larger matrix.
The bank address is constructed using 5 bits, see diagram, 3 bits for x and 2 bits for y. For example bit settings
00100 represent bank address x = 1, y = 0. There must always be a module present at the base address x = 0, y
= 0, otherwise the matrix will not be recognised by the intelligent interface.
If there is a problem with any of the modules used to make up a large matrix then an error will be detected (use the
REPORT? query to discover the cause).
NOTE: Placing a
switch in the “ON”
position sets the
corresponding
address bit to “1”.
