This chapter provides general module information and tasks you must
perform to install a nd pr e pa re your module. A procedur e to verify your
installation is also given. The chapter is divided into the followin g s ections:
The HP E1418A is an 8 or 16 channel digital- t o-ana log converter module
for use in a VXIbus C-s ize mainframe. The modu le is a regis ter-based
device. The module can be programmed via direct register access or, with
the appropriat e driver , by high level commands. This manual de scribes
programming the module using SCPI (Standard Commands for
Programmable Instruments) a nd the SCPI driver.
Each HP E1418A module is a unique instrument having its own output
buffer and error queu e. Multiple modules cannot be combined into a single
instrument.
Each channel can be configured to eith er voltage or current output mo de.
When configu r ed f or voltage output, voltages in the range of -16.0 to
+16.0 Volts can be set. When configured f or current output, current in the
range of -0.02 to + 0.02 Amps can b e s et. The c hannel output mode can be
programmatically set, or, can be forced to either voltage or current by
mechanical jumpers on the terminal module.
Each output channel is individually configurable to be either an isolated
output or a non-isolated output. Cha nne l configuration to is olated or
non-isolat ed is made by individual plu g- on modules for each channel.
Figure 1-1 shows the module.

Ordering Opti onsThe HP E1418A may be ordered from Hewlett-Pa c kard in a va r iety of
configurations. As ordered, the module has t he following options:

Terminal ModulesThe standard HP E1418A Terminal Module provides screw terminals for
connections. Two other terminal options are available with the HP E1418A:
– Crimp an d Ins er t ( O ptio n A3E )
– Ribbon Cable (Option A3H)
– Terminal Module Housing wit hout a terminal module PC board or
The HP E1418A provides great flexibility in configuration. This functional
description will help you become famil iar with the various configurations
and how th e module is structured. A functio nal bloc k diagra m is shown in
Figure 1-2.
Figure 1-2. A Function al Blo ck Diag ra m
Each channel MUST have either an isolated or non-isolated plug-on module installed. Channels may be configured
*
using any combination of Isola ted and Non -Isol ated plug-on modules.
As shown, there are four major assemblies that m a k e up an HP E1418A:
– Channels 1 through 8 main board and VXIbus backplane circuitry.
– Channels 9 through 16 expansion board.
– Isolated or Non- isola ted plug-on modules.
– Terminal Module.
Cha nnels 1–8 m ain board and VXIbus backplane circuitry.
This assembly contains all the VXIbus interface and decoding circuitry.
Isolated and Non-Isolated plug-on modules f or channels 1–8 connect to this
assembly. The panel connectors for the terminal module are also mounte d
on this assemb ly.
The optional C hannels 9–16 expansion board is electrically connected and
mechanically mounted to the main board. I s olated and Non-Isolated
plug-on modules for channels 9–16 connect to this assembly.
Isolated or Non-isolated plug-on modules are required for every channel.
Eight plug-on modules mount to the main board and 8 plug-on modules
mount to the expansion board. Any c omb inati on of is olated or non-isolated
plug-on modules may be used, but every channel must ha ve a plug-on
module ins ta lle d.
The Terminal Module shown i n Figure 1-2 is the standard screw-type
terminal module. This module provides screw connections for each channel
output, the calibration connections, and the external trigger in connections.
This module also contains two jumpers for each channel; one, called the P/J
Jumper, to enable or disable VXIbu s programming of the channel mode
(either voltage or current) and one, called the V/I Jumper, to set the channel
mode when the P/J Jumper is in the Jumper position.
Figure 1-4 shows the logical address switch location and setting. The logical
address switch factory setting is 72. Valid addresses range from 1 to 255.
When used with an HP Command Module the fac t ory set address of
decimal 72 results in a module address of 9 (72 divided by 8). The module
address is used as a secondary address when using HP-IB and a Command
Module. For ex ample, the module address may be 7 09 09, wher e 7 is the
HP-IB interfac e address, 09 is the command module addr ess, and 09 is the
HP E1418A addre ss.
The HP E1418A supports dynamic address configuratio n. When you set the
logical address to 255, the res o ur ce manager s ets the logical address
programmatically.
NoteWhen using an HP C-size mainframe with the HP E1405/E1406 Command
Modules, the logical address setting must be a multipl e of 8.
1. Verify the position of the CAL Store Enable Jumper for your
application. The Jumper, as shipped, is in the CAL position. In this
position, a calibration may be performed and the results stored in
non-volatil e memory. In the Secured positio n, a calibration may be
performed , but may NOT be stored in no n- volat ile memory. This
jumper is described in more detail on page 156.
2. Verify or set the logical address switch as shown in Figure 1-4.
3. Install the module in a mainframe as shown in Figure 1-5.
Installation in a
Mainframe
The HP E1418A may be installed in any slot (except slot 0) in a C-size
VXIbus mainframe. To install in a mainframe:
1. Set the extraction levers out. Slide t he module into an y s lot ( ex cept
slot 0) until the backplane connectors touch.
2. Seat the mo dule by moving the levers toward each other.
3. Tighten the top and bottom screws to secure the modu le in the
mainframe.
Figure 1-5. Installing the HP E1418A in a VXIbus Mainframe
To Remove a Module:To remove a module from a mainframe:
1. Remove any terminal modules.
2. Loosen the top and bottom screws securing the module in the
mainframe.
3. Move the extraction levers away from each other. As the levers are
moved, the module will detach from t he ba ck plane connectors.
4. Slide the module out.
NoteThe extraction levers will not seat and unseat the backplane connectors on
older HP VXIbus mainframes and n on-HP ma inframes . You must
manually seat the connectors by pushing the module into the mainframe
until the front panel is flush with the front of the mainframe. The extraction
levers may be used to guide or remove the module.
Four terminal modules are available for the HP E1418A; a screw- type, a
crimp-and-insert type, a ribbon cable type, and an empty terminal housing
(without a PC board or connectors).
Screw-Type
Terminal Module
(Standard)
The standard terminal module uses screw-type terminals to make
connectio ns. Figure 1-6 may be photocop ied a nd used for wiring layout .
Besides the standard screw-type terminal module, the HP E1418A can be
ordered with the following two optio ns. One option (A3E) provides
crimp-and-insert connectors and terminal housing. The other option (A3H)
provides a ribbon cable con nector and termina l hous ing.
Option A3EHP E1418A Option A3E can be ordered if a crimp-an d -insert terminal
module is desired. This allows you to crimp connectors onto wires which
are then inserted directly into the HP E1418A faceplate connector. Ref er to
the pin-out diagram on page 30 to make the connections. The
crimp-and-insert connector is shown in Figure 1-10.
NoteThe pin numbering on th e crimp-and-insert conn ector may not agree with the
pin nu mberi ng on the HP E1418’s fa ceplate connector. Use the pin
numbering on the faceplate connector to wire the crimp-and-insert connector.
Figure 1-10. Option A3E Crimp- and-I nsert Con necto r
The following accessories are necessary f or use with crimp-and-insert
Option A3E:
Single-Conductor and
Contact
Shielded-Twisted-Pair and
Contacts
A crimp-and-insert contact is crimped onto o ne end of a wire. The other
end is not t erminated. Order HP 91510A.
A crimp-and-insert contact is cr im ped onto each conductor at one e nd of a
shi elded- t wist ed -pair cable. The other end is not terminated. Order
HP 91511A.
Jumper Wire and ContactsA crimp-and-insert contact is crimped onto each end of a single-conductor
ju mper wire. This jump er is typica l ly used to tie t wo p i n s togethe r in a
single crimp-and-insert connector. Order HP 91512A.
Crimp-and-Insert Co ntactsThese co ntacts ma y be crimped onto a conductor and then ins erted into a
crimp-and-insert connector. The crimp too l kit is required to crimp the
contacts ont o a conductor and remove the contact from the connector.
Order HP 91515A.
Crimp-and-Insert ToolsThe hand crimp tool (part number HP 91518A) is used for crimping
contacts ont o a conductor. The pin extractor to ol (pa rt number HP 91519A)
is required f or removing contacts from the crimp-a nd-insert connector.
