Instrument Definition
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 or multiple plug-in modules (for a Switchbox or Scanning
Voltmeter Instrument).
Switch Description The HP E1364A 16-Channel Form C Switch Module is a B-Size VXIbus
and VMEbus register-based product which can be used for
switching/scanning, control, and digital output applications. The switch can
operate in a B-Size VXIbus or VMEbus mainframe or (with an adapter) in a
C-Size VXIbusmainframe. The module has 16 channels of Form C relays.
Each channel includes a relay with common (C), normally open (NO), and
normally closed (NC) contacts.
For the Form C Switch, switching consists of opening or closing a channel
relay to provide alternate connections to user devices. Scanning consists of
closing a set of relays, one at a time. By adding jumpers and
pullup/pulldown resistors, the switch can be used to control external user
devices or as a digital output device.
Basic Operation As shown in Figure 1-1, the Form C Switch consists of 16 channels
(channels 00 through 15). Each channel uses a latching relay. As required,
jumpers can be added to connect +5 V or +12 V for control or digital output
applications. Also, pullup resistors can be added for digital output
applications.

Each channel is switched by opening or closing the appropriate channel
relay. Since the relays are latching, the relay remains in the last state during
power-up or power-down. When a reset occurs, all channel commons (C)
are connected to the corresponding normally closed (NC) contacts. User
inputs/outputs to each channel are via the NO, NC, and C terminal
connectors on the terminal module.

Typical
Configuration The Form C Switch accepts user inputs up to 250 V dc or 250 V ac peak
(177 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 the maximum scan rate is about 50 Hz.
As noted, the switch may be configured for general purpose
switching/scanning, control, or digital output applications. For general
purpose switching or scanning, no additional configuration is required. To
configure the switch for control applications, install jumpers to connect a
+ 5V or + 12V source and GND. To configure the switch for digital output
applications, connect jumpers and install pullup/pulldown resistors as
required. See Chapter 2 for configuration details.
For a SCPI (Standard Commands for Programmable Instruments)
environment, multiple Form C Switches can be configured as a switchbox
instrument. For a switchbox instrument, all switch channels within the
instrument can be addressed using a single interface address. Single,
multiple, or continuous scanning of specified switch channels is available
for any switchbox configuration.
Programming the Switch
To program the Form C Switch using SCPI, you must know the module’s
logical address, module number, and the SCPI commands to be used.
Guidelines to select SCPI commands for the Form C Switch 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, Form C Switch
Registers, for information on Form C Switch registers.
Specifying SCPI
Commands To address specific channels within a Form C Switch, you must specify the
SCPI command and switch channel address. For the Form C Switch, use
CLOSe <channel_list> to connect the normally open (NO) terminal to the
common (C) terminal for the channels specified. Use OPEN <channel_list>
to connect the normally closed (NC) terminal to the common (C) terminal
for the channels specified. Use SCAN <channel_list> to close the set of
channels specified, one channel at a time.
Switch Channel
Addresses For the Form C Switch, the channel address (<channel_list>) has the form
(@ccnn) where cc = switch card number (01-99) and nn = channel numbers
(00-15).
Chapter 1 Getting Started with the HP E1364A 13
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

You can address single channels (@ccnn); multiple channels
(@ccnn,ccnn,...); sequential channels (@ccnn:ccnn); groups of sequential
channels (@ccnn:ccnn,ccnn:ccnn); or any combination.
Switch Card
Numbers The switch card number depends on the switchbox configuration
(single-module or multiple-module) set for the switches. (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 HP 75000
Series B Installation and Getting Started Guide for a definition of logical
addresses.)
Example:
Multiple-Module
Switchbox Card
Numbers
Assume the three Form C Switches in the following figure form a
switchbox instrument with switch logical addresses of 120,121, and 122.
Since card number 01 is assigned to the module with the lowest logical
address, etc., the card numbers are as shown.
Switch Channel
Numbers Form C Switch channel numbers are 00 through 15. The channels can be
addressed using channel numbers or channel ranges. For a single-module
switchbox, channel ranges can span across the channels. For
multiple-module switchboxes, channel ranges can span 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 range must be from a lower channel
number to a higher channel number. For example, CLOS (@100:215) is
acceptable, but CLOS (@215:100) generates an error.

Initial Operation
An example program follows which uses Hewlett-Packard BASIC and the
SCPI language to get you started using the Form C Switch. The example
assumes an HP 9000 Series 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.)
This program closes channel 02 of a Form C Switch at logical address 120
(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 HP 75000 Series B Installation and Getting Started
Guide for information on addressing.
Example: Close Form C Switch Channel
10 OUTPUT 70915;"CLOS (@102)" ! Close channel 02
20 OUTPUT 7091 5;"CLOS? (@102)" ! Query channel 02 state
30 ENTER 70915;Value ! Enter result into Value
40 PRINT Value ! Display result
50 END

Warnings and Cautions
Warning SHOCK HAZARD. Only qualified, service-trained personnel who
are aware of the hazards involved should install, configure, or
remove the module. Use wire rated for the highest input voltage
and remove all power sources from the mainframe and installed
modules before installing or removing a module.
Caution MAXIMUM VOLTAGE/CURRENT. Maximum allowable voltage per
channel for the module is 250 Vdc or 250 Vac RMS (350 V ac peak).
Maximum current per channel is 1 Adc or 1 Aac RMS (non-inductive).
Maximum power input is 40 W (dc) or 40 VA (ac) per channel or 320 W
(dc) or 320 VA (ac) per module. Exceeding any limit may damage the
module.
Caution CONNECTING + 5V + 12V: On the module, the backplane + 5V line is
fused at 4 A and the + 12V line at 1 A. When connecting + 5V or + 12V to
the Form C Switch, install appropriate pullup resistors to prevent shorting
the power supplies. Also, the total current drawn by all circuits connected to
the Form C Switch must not exceed the fuse rating for the supplies used.
