HP plug-in modules installed in an HP mainframe are treated as
independent instruments each having a unique secondary HP-IB address.
Each instrument is also assigned a dedicated error queue, input and output
buffers, status registers and, if applicable, dedicated mainframe memory
space for readings or data. An instrument may be composed of a single
plug-in module (such as a counter) or multiple plug-in modules (for a
switchbox or scanning voltmeter instrument).
Matrix Description
The HP E1361A 4 X 4 Relay Matrix module is a B-Size VXIbus and
VMEbus register-based product which can be used for matrix switching or
scanning. The matrix can operate in a B-Size VXIbus or VMEbus
mainframe or (with an adapter) in a C-Size VXIbus mainframe.
The relay matrix consists of 16 latching relays (channels 00 through 15).
The module is factory-configured as a 4 X 4 matrix. By removing jumpers,
you can configure the module into a dual 4 X 2 matrix arrangement.
For the matrix, switching consists of closing a specified channel relay to
provide row and column connections. Scanning consists of closing a set of
relays, one relay at a time. You can open or close any combination of relays.

Basic Operation Figure 1-1 shows simplified user connections for a matrix in the 4 X 4
configuration. To connect a specified row (0-3) to a specified column (0-3),
close the relay at the crosspoint of the row and column. For example, close
crosspoint relay 32 to connect row 3 to column 2. In the 4 X 4 matrix
configuration, user row inputs can be to either Bank A or Bank B rows.
When a relay is closed, HIGH (H) and LOW (L) for the specified row and
column are simultaneously connected. When a relay is opened the
row/column inputs to the relay are disconnected. Since channel relays are
latching, all relays remain in their current state during power-up or
power-down. At reset, all relays are opened.

Typical
Configuration The relay matrix module accepts user inputs up to 250 V dc or 250 V ac
RMS at 1 A dc or ac RMS (non-inductive). Maximum rated power capacity
is 30 W or 40 VA per channel. Channel closure time is about 15 msec, so
maximum scan rate is about 50 Hz.
As noted, the matrix may be configured for 4 X 4 or dual 4 X 2 matrix
applications. For 4 X 4 matrix operation, no additional user configuration is
required. To configure the matrix for dual 4 X 2 operation, you can remove
factory-installed jumpers JM1 through JM8 (see Chapter 2 for jumper
locations).
For a SCPI (Standard Commands for Programmable Instruments)
environment, single or multiple relay matrixes can be configured as a
switchbox instrument. For a switchbox instrument, all channels within the
instrument can be addressed using a single interface address.
Programming the Matrix
To program the relay matrix using SCPI, you must select the computer
language, interface address and SCPI commands to be used. Guidelines to
select SCPI commands for the relay matrix follow. See the HP 75000
Series B Installation and Getting Started Guide for interface addressing and
computer language information.
Note This discussion applies only to SCPI (Standard Commands for
Programmable Instruments) programming. See Appendix B, “Relay Matrix
Registers” for information on relay matrix registers.
Specifying SCPI
Commands To address specific channels (relays) within a relay matrix, you must
specify the SCPI command and matrix channel address. Use CLOSe
channel_list to close specified relay(s); OPEN channel_list to open the
relays; and SCAN channel_list to close the set of relays specified.
Matrix Channel Addresses
For the relay matrix, the channel address (channel_list) has the form
(@nnrc) where nn = matrix card number (01-99), r = matrix row number
(0-3), and c = matrix column number (0-3).
You can address single channels (@nnrc); multiple channels
(@nnrc,nnrc,...); sequential channels (@nnrc:nnrc); groups of sequential
channels (@nnrc:nnrc,nnrc:nnrc); or any combination.

Matrix Card Numbers
The matrix card number depends on the switchbox configuration
(single-module or multiple-module) set for the matrixes. (Leading zeroes
can be ignored for the card number.) For a single-module switchbox, the
card number is always 01.
For a multiple-module switchbox, the card numbers are 01, 02,...,nn. The
module with the lowest logical address is card number 01, the module with
the next-lowest logical address is card number 02, etc. (See the appropriate
Installation and Getting Started Guide for a definition of logical addresses.)
Example: Multiple-Module Switchbox Card Numbers
Assume the three relay matrixes in the following figure form a switchbox
instrument with logical addresses of 120, 121, and 122. The module with
the lowest logical address is card number 01. The card numbers are shown
in the following figure.
Matrix Channel Numbers
Relay matrix channel numbers are 00-03, 10-13, 20-23, and 30-33.
Specifying a channel number specifies the associated crosspoint relay. For
example, CLOS (@123) closes crosspoint relay 23 of card 01 which
connects row 2 to column 3.
Channels can be addressed using channel numbers or channel ranges. For a
single-module switchbox, channel ranges can span across the channels. For
a multiple-module switchbox, channel ranges can span across the channels
of all modules in the switchbox. Use commas (,) to form a channel list or
use a colon (:) to form a channel range.
Only valid channels can be accessed in a channel list or channel range.
Also, the channel list or channel range must be from a lower channel
number to a higher channel number. For example, CLOS (@100:233) is
acceptable, but CLOS (@233:100) generates an error.

Example: Relay Matrix Channel Lists/Ranges
Channel Lists:
CLOS (@100,112) Close relays 00 and 12 on card 01
OPEN (@203,210) Open relays 03 and 10 on card 02
Channel Ranges:
OPEN (@100:133) Open all relays on card 01
SCAN (@100:133) Scan all relays on card 01
Initial Operation
An example program follows which uses Hewlett-Packard BASIC and
SCPI language to get you started using the relay matrix. The example
assumes an HP 9000 Series 200/300 controller and a Hewlett-Packard
Interface Bus (HP-IB). [HP-IB is the Hewlett-Packard implementation of
the IEEE 488.2-1987 standard.]
The program closes channel 31 of a 4 X 4 relay matrix at logical address
120 (secondary address = 120/8 = 15) to connect row 3 to column 1 and
queries the result. The result is returned to the controller and displayed
(1 = relay closed, 0 = relay open).
Example: Connect Row 3 to Column 1 (4 X 4 Matrix)
10 OUTPUT 70915;"CLOS (@131)" Connect row 3 to col 1
20 OUTPUT 70915;"CLOS? (@131)" Query relay 31 state
30 ENTER 70915;Value Enter result into Value
40 PRINT Value Display result

Warnings and Cautions
Warning SHOCK HAZARD. Only qualified, service-trained personnel
who are aware of the hazards involved should install, configure,
or remove the relay matrix. Use only wire rated for the highest
input voltage and remove all power sources from the
mainframe and installed modules before installing or removing
a module.
Warning CHANNEL WIRING INSULATION. All channels that have a
common connection must be insulated so that the user is
protected from electrical shock in the event that two or more
channels are connected together. This means wiring for all
channels must be insulated as though each channel carries the
voltage of the highest voltage channel.

Caution MAXIMUM VOLTAGE/CURRENT. Maximum allowable voltage
per crosspoint relay for the relay matrix is 250 V dc or 250 V ac
RMS (350 V ac peak). Maximum current per relay is 1 A dc or 1
A ac RMS (non-inductive). Maximum power input is 40 W (dc)
or 40 VA (ac) per relay. Exceeding any limit may damage the
relay matrix module.
Caution STATIC-SENSITIVE DEVICE. Use anti-static procedures when
removing, configuring, and installing a module. The relay
matrix is susceptible to static discharges. Do not install a
matrix module without its metal shield attached.
Connecting User Inputs
The relay matrix consists of a component card and a terminal block. User
inputs to the matrix are to the HIGH (H) and LOW (L) terminal connectors
on the terminal block. Figure 2-1 shows the terminal block features and
Figure 2-2 shows how to connect user (field) wiring to the terminal block.
