Chapter 1
Getting Started
Using This Chapter
This chapter describes the HP E1343A 16-Channel High Voltage Relay,
E1344A 16-Channel General Purpose Thermocouple High Voltage Relay,
E1345A 16-Channel Relay, and HP E1347A 16-Channel Thermocouple
Relay Multiplexer Modules, and shows how to program the modules using
SCPI commands (Standard Commands for Programmable Instruments).
This chapter contains the following sections:
•Multiplexer Module Description. . . . . . . . . . . . . . . . . . . . . . page 11

Multiplexer Module Description
Refer to Figure 1-1 for the following explanations of all four 16-Channel
Relay Multiplexer Modules.
General Description The multiplexer module switches (multiplexes) up to 16 channels. Each
channel provides High (H), Low (L), and Guard (G) connections.
The multiplexer module consists of a component assembly and a terminal
module. The channel relay switches are on the component assembly. The
fieldwiring from user sources (e.g., thermocouples) connectsto the terminal
module. The terminal module also provides connections for multimeters,
voltmeters, counters, and other measuring devices.
Multiplexer
Channel
Descriptions and
Connections
The channel relay switches are separated into two banks, Bank 0 and
Bank 1. Channels 00 to 07 are in Bank 0 and channels 08 to 15 are in
Bank 1. Each bank has its own H, L, and G Common terminals to which the
channel switches connect.
The channel switches also connect, through the AT and BT Tree Switches,
to the AT and BT Tree Switch Terminals, respectively. The Bank 0 channels
connect to the AT Tree Switch Terminals and the Bank 1 channels connect
to the BT Tree Switch Terminals. An additional tree switch, the AT2 Tree
Switch, provides connection of the Bank 1 channels to AT Tree Switch
Terminals. Use channel numbers 90, 91, and 92 to select the AT, BT, and
AT2 Tree Switches, respectively.
Connecting to the TreeSwitch Terminals is the preferred method to connect
measuring devices, like multimeters, to measure the multiplexer channels.
This allows you to connect the measuring device to either the Bank 0 or
Bank 1 channels at any given time, or to the channels of both banks.
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

12 Getting Started Chapter 1
The AT Tree Switch Terminals also connect to the H, L, and G connections
on the Analog Bus Connector. The BT Tree Switch Terminals also connect
to the I+, I-, and IG connections on the Analog Bus Connector. The Analog
Bus Connector provides direct channel connections between multiple
multiplexer modules, and connections between a multiplexer module and
the HP E1326/E1411 Multimeters. Cables make the necessary connections
without the need to externally wire the multimeter/multiplexer modules via
the terminal modules.
The 16-Channel Thermocouple Relay Multiplexer Modules (HP E1344A
and E1347A) uses the RT Tree Switch (Channel 93) to connect the
thermistor on the terminal module to the Bank 1 channel common. The
thermistor can be measured to determine the temperature inside of the
terminal module to compensate for temperature measurements made with
thermocouples (see Chapter 3).
Each channel High (H) line has a jumper on the terminal module that may
be removed to add filter components (see Chapter 2 under the “Adding
Signal Conditioning Components/Current Shunts” heading). Each Bank 0
and Bank 1 common line, the AT and BT Tree Switch, and the Analog Bus
lines all have 100 ohm resistors in series with each line. The resistors
provide relay protection and are located on the component module.

Programming the Multiplexer Module
The multiplexer modules are programmedeither in aswitchbox or scanning
voltmeter configuration. To program the multiplexer modules using the
StandardCommandsfor ProgrammableInstruments(SCPI),youmustselect
the controller language, interface address, and SCPI commands to be used.
See the HP 75000 Series B Installation and Getting Started Guide or the
HP E1406 Command Module Manual for interface addressing and
controller language information of multiplexer modules in a switchbox or
scanning voltmeter configuration. If using the HP E1300 Mainframe or
HP E1405 Command Module, you MUST have version 06.00 (or
greater) firmware for the Multiplexer Modules to properly identify.
Note This discussion applies to SCPI programming. See Appendix B
(“16-Channel Relay Multiplexer Registers”) for details on multiplexer
modules registers.
Selecting Channels To address specific channels within a multiplexer module in a switchbox or
scanning voltmeter configuration, you must:
•send the appropriate SCPI command string to the switchbox or
scanning voltmeter (e.g., CLOSe, OPEN, etc.)
•specify the card number
•specify the channel number
Multiplexer Card
Numbers The card number identifies the module within a switchbox or scanning
voltmeter configuration. The switch module with the lowest logical address
is always card number 01. The card number with the next successive logical
address is 02, and so on. Figure 1-2 illustrates the card number and logical
address of a typical single module switchbox.
Figure 1-2. Card Numbers for a Single Module Switchbox
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

Getting Started 15Chapter 1
Figure 1-3 illustrates the card numbers and logical addresses of a typical
multiple module switchbox. Figure 1-4 illustrates the card numbers of a
typical multiple module scanning voltmeter.
The logical addresses noted in Figures 1-2, 1-3, and 1-4 apply to modules
installed in an HP 75000 Series B Mainframe (HP Model Number
E1300/E1301) or in a mainframe with an HP E1405/E1406 Command
Module. See the HP 75000 Series B Installation and Getting Started Guide
or the HP E1406 Command Module Manual for more information on
switchboxes and scanning voltmeter configurations, and logical addressing.
If using theHP E1300 Mainframe or HP E1405 Command Module, you
MUST have version 06.00 (or greater) firmware for the 16-Channel
Multiplexer Modules to properly identify. For uses in other systems or
mainframes, see the appropriate manuals.

Multiplexer Channel
Address Forthe16-ChannelMultiplexers,thechanneladdress(channel_list) isinthe
form:
n (@ccnn) for a single channel;
n (@ccnn,ccnn) for multiple channels;
n (@ccnn:ccnn) for sequential channels;
n (@ccnn:ccnn,ccnn:ccnn) for groups of sequential channels;
n or any combination of the above.
where "cc" is the card number and "nn" is the channel number.
For example, the command string to close channel 02 of card number 1 is:
CLOSe (@0102)
Since "cc" (the card number) must be sent, it becomes part of the channel
number. Also, you can ignore leading zeros in the card numbers. Thus, to
close channel 02, send "102" instead of "0102". To close theabove channel,
execute:
CLOSe (@102)
SCPI Command
Format Used in This
Manual
You can send SCPI commands in either a short or long form. A long form
example is:
CLOSe (@102)
The same command shown without the lower case letters is the short form.
The command then becomes:
CLOS (@102)
Some commands in this manual are shown with brackets ([ ]). These are
impliedor optional commands thatyou do not haveto execute. For example,
the ROUT command is an implied command and is shown in this manual as:
[ROUT:]CLOS (@102)
Thus, to execute these commands, simply enter:
CLOS (@102)
See Chapter 5 for more explanation about SCPI commands and how to send
them.

Getting Started 17Chapter 1
Initial Operation
Use the following program example to verify initial multiplexer operation
by closing a channel and querying channel closure. The example first resets
the switchbox and then closes channel 02 of a single multiplexer module
(card number 1) in the switchbox. The program next queries the channel
closure state. A returned "1" shows that the command to close the channel
has been sent to the switchbox. A returned "0" shows that the command to
close the channel has not been sent to the switchbox.
The computer used in the example is an HP Series 200/300 computer with
HP BASIC as the program language. The computer interfaces to the
mainframe using the Hewlett-Packard Interface Bus (HP-IB)1. The HP-IB
interface select code is 7, the HP-IB primary address is 09, and the HP-IB
secondary address is 14. Refer to the HP 75000 Series B Installation and
Getting Started Guide for addressing information.
Example: Reset the switchbox and close channel 02
10 OUTPUT 70914;"*RST" Opens all channels.
20 OUTPUT 70914;"CLOS (@102)" Close channel 02.
30 OUTPUT 70914;"CLOS? (@102)" Query channel 02 state.
40 ENTER 70914;Value Enter results into Value.

Warnings and Cautions
WARNING SHOCK HAZARD. Only service-trained personnel who are aware of
the hazards involved should install, remove, or configure the
modules. Before installing any module, disconnect AC power from the
mainframe and from user wiring.
To prevent electrical shock, all wires to the channel connections must
be insulated to at least 120 Vrms (170 V peak).
Caution MAXIMUM VOLTAGE/CURRENT. Maximum voltage that may be
applied between High (H), Low (L), and Guard (G) terminals is 170 V
dc or 120 V rms (170 V peak) for the E1345A/47A or 250 V dc or AC
RMS (354 V peak) for the E1343A/44A. Maximum current is 50mA
(non-conductive) per channel.
STATIC ELECTRICITY. Static electricity is a major cause of
component failure. To prevent damage to the electrical components in
the multiplexer module, observe anti-static techniques whenever
removing a module from the mainframe or whenever working on a
module.
