General Information

The terms "Form C switch" and "switch" are both used in this manu al to
refer to the HP E1442A 64-Channel Form C Switch Module which is a
VXIbus C-size register-based slave device that can operate in a C-size
VXIbus mainframe or a VMEbus mainframe.

The switch "instrument" is the firmware running in the E1405/E1406
Command Mod ule. This firmware is the instrum ent driver providi ng SC PI
(Standard Commands for Programm able Instrum en ts) programm ing
capabilit y. The term "switchbox" is used to refer to a switch instrument
made up of one or more switch modules.

Programmin g the HP E1442A can be done th rough th e command m odul e
using the Standa rd Commands for Programmable Instrum ents (SC PI - see
Chapter 3), or via direct register access (register-based programming - se e
Appendix B).

• Option 020: Screw Terminal Form A Confi guration Terminals

(NOTE: Option 020 has no connection to the NC relay contact.)

Module Use and Address Selection

You can use the switch module as a switchbox in two ways:

• As one module in a group of switch modules called a switchbox.

The first module must be addressed so it can be recognized as an
instrument and the other modules in the group have addresses

sequentially following the first module e.g., 120, 121, 122 ....

• As a single-switchbox switch mod ule. The module must be

addressed so it can be recognized as an instrument.

NOTE Addressing channels on a switch module depends on how you use the

module. Figure 1-2 on card numbers (module num bers) and channel
addresses describes how your choice of using the module determines ho w
you access a particular channel on the switch card (modu le).

Multiple­Module

Channel 45 on card number 02 is
addressed by (@245).

This mainframe has two switchboxes:
a) one multiple-module switchbox
at address 120, and
b) one single-module switchbox
at address 48.

Figure 1-2. Logical Address, Card (Mod ule) Numb er and Chan nel Ad dress

Chapter 1 HP E1442A Module Setup 13

Setting the Module Address Switch

The logical address switch (LADDR) factory setting is 120. Valid
addresses are from 1 to 254. The Form C switch module can be configured
as a single instrument, or as a switchbox. Refer to the C-Size VXIbus
Systems Configura tion Guide for addressing information. Refer to
Figure 1-3 for switch position in fo rmation .

Note When usin g an HP E1405A/B or E140 6A, the address switch value must be

a multiple of 8 if th e m odule is the first module in a swi tchbox used with a
VXIbus command mo dule usi ng SCPI comm ands.

Figure 1-3. Setting the Logi cal Address

14 HP E1442A Module Setup Chapter 1

Setting Interrupt Priority

Interrupts are enabled at power-up, after a SYSRESET, or after resetting the
module via the control register. An interrupt is generated after any channel
enable register is accessed when interrupts are enabled. The interrupt is
generated approximately 13 ms after one of the registers is accessed. The
interrupt priority jumper selects which priority level will be asserted. The
interrupt priority jumper is set in positi on 1 as shipped from the factory. For
most applications th is priority level shou ld not have to be changed. The
interrupts are disabled when set to level X. The interrupt priority jumpers
are identified on the sheet metal shield. A hole has been cut into it for
access. Interrupts can also be disabled using th e Control Regist er.

To change the setting, simply remove the jumper or jumpers from their
current position and place on the level you desi re. If the card uses two 2-pin
jumpers, both ju mpers mu st be placed in the same row for proper operation.

Note Con sult your mainframe manual to make sure backplane jumpers are

configured correctly. If you are using the HP E1401A/B Mainframe, these
jumpers are automatically set when the card is installed.

Connecting User Inputs

The Form C switch consists of a component module and a terminal module. The
user connects inputs to the Form C switch NO (Normally Open), NC (Norm ally
Closed), and C (Common) terminal connections on one of the three available
terminal modules. Figure 1-1 earlier in this chapter shows the switch module and

Usi ng the Internal

Buses

The HP E1442A 64-Channel Form C Switch Module con tains in ternal
buses that you can connect any channel co ntact to. Figure 1-7 below shows
channels 0 and 63 and the internal bus structure. There is a bus for the
common, the normally closed (NC), and the normally open (NO) contacts.
Other jumpers provide the means to connect the NC and NO contacts to a
fused +5V pull-up voltage, or to be connected as pull-downs to ground. The
common can be connected to ground. Figure 1-8 shows where you can find
the component/jum pe r locations on the modu le.

! WARNINGS and CAU TIONS

WARNING SHOCK HAZARD. Only qualified, service-trained personnel

aware of the hazards involved should install, configure, or
remove the module. Disconnec t all power sources from the
mainframe, the terminal module and installed modules before
installing or removing a module.

22 HP E1442A Module Setup Chapter 1

WARNING SHOCK HAZARD. When handling user wiring connected to the

terminal module, consider the highest voltage present
accessible on any terminal.

WARNING SHOCK HAZARD. Use wire with an insulation rating greater

than the highest voltage which will be present on the terminal
module. Do not touch any circuit eleme n t connected to the
terminal module if any other connector to the terminal module
is energized to more than 30 VAC RMS or 60 VDC.

CAUTION MAXIMUM VOLTAGE/CURRENT. Maximum allowable volta ge

per channel terminal -to-termina l or terminal -to-cha ssis for the
switch module is 150 Vdc or 150 Vac RMS (210 Vac peak).
Maximum curre n t per channel is 1 Adc or 1 Aac RMS
(non-inductive). Maximum transient voltage is 1300V peak.
Maximum power input is 40 Wdc or 40 VA per channel, 320 Wdc
or 320 VA per module. Exceeding any limit or use outside the
parameters specified in Appendix A and by these warnings and
cautions may damage the switch module and impair the
protection provided by the module.

CAUTION WIRING TERMINAL MODULE: When wiring to the terminal

connectors on the E1442A terminal module, be sure not to
exceed a 5mm strip back of insulation to prevent the possibility
of shorting to other wiring on adjacent termi nals .

CAUTION STATIC-SENSITIVE DEVICE. Use anti-static procedures when

removing, con figuring, cleani ng and installing a module . The
switch module is susceptible to static discharges; do not install
the module without its metal shield attache d.

Chapter 1 HP E1442A Module Setup 27

Initial Operation

The following program uses Hewlett-Packard BASIC and SCPI (Standard
Commands for Programmable Instruments) language to get you started using
the Form C switch. The example assumes a n HP 9000 Se ries 200/300 (or
equivalent) computer and a Hewlett-Packard Interface Bus ( HP-IB). (HP-IB is
the Hewlett-Packard implementation of the IEEE 488.2-1987 standard.)

The Normally Open (NO) contact of each Form C relay is "open" and the
Normally Closed (NC) conta ct of each Form C relay is "closed" when the
switch is deactivated (the Common terminal (C) is connected to NC at
power-on, after reset or after an open command).

This program closes channel 02 of a Form C switch at logical address 12 0
(secondary address = 120/8 = 15) and queries the channel closure state. The
result is returned to the computer and displayed ( 1 = channel closed,
0 = channel open). See the C-Size VXI bus Systems Configura tion Guide
for information on addressing.

Example: Close Form C Switch Channel

10 OUTPUT 70915;"CLOS (@102)" ! Close channe l 02 .
20 OUTPUT 70915;"CLOS? (@102)" ! Query channel 02 state.
30 ENTER 70915;Value ! Enter result into V alu e.
40 PRINT Value ! Display result.

Programmin g the

Switch

Note This discussion applies only to SCPI programming using the HP switchbox

Specifying SCPI

Commands

To program the Form C switch using SCPI, you must select the compu t er
language, interface address, and SCPI commands to be used. Guideli nes to
select SCPI commands for the Form C switch follow. See the C-Size
VXIbus Systems Configur atio n Guide for interface addressing and computer
language information.

driver version provided with this module. See Appendix B, "Form C
Switch Register Programming & Definitions", for information on Form C
switch registers.

To address specific channels within a Form C switch, you m ust sp ecify the
SCPI command and switch channel address. For the Form C switch, use

CLOSe <channel_list> to connect th e normally op en (NO) terminal to the

common (C) terminal for the channels specified. Use use

OPEN <channel_list> to conne ct the normally closed (NC) terminal to th e

common (C) terminal for the channels specified. Use
to close the set of channels specified, one channel at a time.

SCAN <channel_list>

28 HP E1442A Module Setup Chapter 1

Channel Addresses Channel add resses (cha nnel_l ist) have the form (@ccnn) where cc = switch

card number (01-99) and

nn = channel numbers (00-63).

You can address single channels

(@ccnn,ccnn,...); sequential channels (@ccnn:ccnn); groups of sequential

channels

(@ccnn:ccnn,cc nn:cc nn); or any combination.

(@ccnn); multiple channels

Card Numbers The switch card number depends on the switchbox configu ration (single

module or multipl e modul e) set for the switches. (Leading zeroes can be
ignored for the card number. ) For a single-module switchb ox, 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 c ard number 01, the module with the
next lowest logical address is card number 02, etc. (See the C-Size VXIbus
Systems Configuration Guide for a definition of logical addresses.)

Figure 1-13. Multiple- Mo dule Swi tchb ox Card Numb er s

Assume that three Form C switches are c onfigured to f orm a switchbox
instrument with logical addresses of 120, 121, and 122. Since card number 01
is assigned to the module with the lowest logical address, card number 01 is
assigned to the card at logical address 120. Card number 02 is assigned to the
card at address 121 and card number 03 is a ssigned to the c ard a t address 122.

Chapter 1 HP E1442A Module Setup 29

Channel Numbe rs,

Channel Lists,

Channel Ranges

Form C switch channel numbers are 00 through 63. The channels can b e
addressed using channel numbers or channel ranges. For a single-modul e
switchbox, channel ranges can sp an across the channels. For multiple­module switchboxes, channel ranges can sp an across the channels of all
modules.

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 rang e must be f rom a lower channel
number to a higher channel number. For example,
