Module Description
The HP E1418A is an 8 or 16 channel digital-to-analog converter module
for use in a VXIbus C-size mainframe. The module is a register-based
device. The module can be programmed via direct register access or, with
the appropriate driver, by high level commands. This manual describes
programming the module using SCPI (Standard Commands for
Programmable Instruments) and the SCPI driver.
Each HP E1418A module is a unique instrument having its own output
buffer and error queue. Multiple modules cannot be combined into a single
instrument.
Each channel can be configured to either voltage or current output mode.
When configured for voltage output, voltages in the range of -16.0 to
+16.0 Volts can be set. When configured for current output, current in the
range of -0.02 to + 0.02 Amps can be set. The channel output mode can be
programmatically set, or, can be forced to either voltage or current by
mechanical jumpers on the terminal module.
Chapter 1 Module Setup and Installation 13

Each output channel is individually configurable to be either an isolated
output or a non-isolated output. Channel configuration to isolated or
non-isolated is made by individual plug-on modules for each channel.
Figure 1-1 shows the module.

HP E1418A Option 002 8-Channel D/A Converter with Isolated Outputs
HP E1418A Option 003 16-Channel D/A Converter with Isolated Outputs
Field Kits The module can also be user configured as described beginning on page 169
of this manual. The following field expansion and configuration kits are
available:
Description Use
HP E1523A Single Channel Isolated
plug-on module To change a single channel from non-isolated to isolated output.
HP E1524A Expansion kit, 8-Channel
Non-Isolated Outputs To add 8 additional non-isolated channels to an existing 8-channel
module.
HP E1525A Expansion kit, 8-Channel
Isolated Outputs To add 8 additional isolated channels to an existing 8-channel module.
Terminal Modules The standard HP E1418A Terminal Module provides screw terminals for
connections. Two other terminal options are available with the HP E1418A:
–Crimp and Insert (Option A3E)
–Ribbon Cable (Option A3H)
–Terminal Module Housing without a terminal module PC board or
connectors included (Option 135)

Functional Description
The HP E1418A provides great flexibility in configuration. This functional
description will help you become familiar with the various configurations
and how the module is structured. A functional block diagram is shown in
Figure 1-2.
* Each channel MUST have either an isolated or non-isolated plug-on module installed. Channels may be configured
using any combination of Isolated and Non-Isolated plug-on modules.
Figure 1-2. A Functional Block Diagram
16 Module Setup and Installation Chapter 1

As shown, there are four major assemblies that make up an HP E1418A:
–Channels 1 through 8 main board and VXIbus backplane circuitry.
–Channels 9 through 16 expansion board.
–Isolated or Non-isolated plug-on modules.
–Terminal Module.
Channels 1–8 main board and VXIbus backplane circuitry.
This assembly contains all the VXIbus interface and decoding circuitry.
Isolated and Non-Isolated plug-on modules for channels 1–8 connect to this
assembly. The panel connectors for the terminal module are also mounted
on this assembly.
The optional Channels 9–16 expansion board is electrically connected and
mechanically mounted to the main board. Isolated 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 combination of isolated or non-isolated
plug-on modules may be used, but every channel must have a plug-on
module installed.
The Terminal Module shown in 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 VXIbus 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.

Front Panel Connectors
Figure 1-3 shows the connections at the front panel connectors of the main
module.

18 Module Setup and Installation Chapter 1

Setting the Logical Address Switch
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 factory 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 example, the module address may be 7 09 09, where 7 is the
HP-IB interface address, 09 is the command module address, and 09 is the
HP E1418A address.
The HP E1418A supports dynamic address configuration. When you set the
logical address to 255, the resource manager sets the logical address
programmatically.
Note When using an HP C-size mainframe with the HP E1405/E1406 Command
Modules, the logical address setting must be a multiple of 8.
Figure 1-4. Setting the Logical Address
Chapter 1 Module Setup and Installation 19

Module Installation
To install the module:
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-volatile memory. In the Secured position, a calibration may be
performed, but may NOT be stored in non-volatile memory. This
jumper is described in more detail on page 159.
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 the module into any slot (except
slot 0) until the backplane connectors touch.
2. Seat the module by moving the levers toward each other.
3. Tighten the top and bottom screws to secure the module in the
mainframe.
