C-Size Adapter Description
The HP E1403C and HP E1407A Adapter Modules allow an A- or B-Size
VMEbus/VXIbus module to connect to a C-Size VXIbus Mainframe. The
regular adapters connect a single slot VMEbus/VXIbus module to the
mainframe. Option 10 connects two-slot modules to the mainframe
(however, it only conne cts the modul e to the P1 and/or P2 connec tor of only
one slot). The following gives the features of the adapters.

VME modules. These pins may be isolated from the backplane.
•Meets VMEbus driving and loading specifications.
•Provides proper timing for data Transfer Acknowledgment (DTACK)
and Interrupt Signals (IRQ).
•Provides connectivity for HP B-size modules or any P1-only VXIbus

This chapter shows how to install/ remove B-size VXIbus modules into/ from
the HP E1403C or HP E1407A C-Size Adapter Module, and how to
install/remove the adapter module into a C-Size VXIbus Mainframe.
NoteThe procedures in this chapter shows installation/removal o f the Adapter
Module into/from the HP E1401A High Power Mainframe. The
procedures for other mainframes are similar to these procedures.
Preparing for Installation
•Be sure to set the logical address of the module to be installed into the
adapter to the correct address (see the module manual).
•Be sure to use clean handling and anti-static handling of the module.
Chapter 2
•Be sure there are no external connections to the modules.
Installing A-Size VMEbus Modules (HP E1403C Only)
Install A-Size VMEbus Modules only in the HP E1403C Adapter Module.

NoteDuring power-up, the resource manager recognizes a module in the slot
with the HP E1403C or HP E1407A Adapter Module installed with or
without a B-Size module installed in the adapter module. Thus, to prevent
any error generation, be sure a B-Size module is installed in the adapter
module before power-up.

NOTE:
When removing the B-size
Module from the Adapter
Module, the Adapter Module
may be pulled out of the
mainframe. If that happens,
carefully pull the B-size Module
out of the Adapter Module,
without damaging any exposed
components on the B-size
Module.
Using the “D” Ring, pull the C-Size Adapter Module out of the Mainframe.
This chapter shows how to use the adapter modules. It includes a block
diagram for both the HP E1403C and HP E1407A Adapter Modules as well
as connector pinouts. This chapter also includes, for the HP E1407A
Adapter Module, instructions on how to use and install the J2 connector
cable, how to select the di rect ion (t o or fro m the mainf rame’s back plane) of
the trigger signals on the ECL and TTL trigger lines, and how to select
unbuffered or buffered SUMBUS connections.

Module.
Installing the J2 Connector Cable (HP E1407A Only)
Purpose of the
J2 Cable
CautionDamage to a VMEbus module, adapter module, mainframe, or
The HP E1407A C-Size Adapter Module is shipped with a long and short J2
Connector Cables. The long J2 cable allows for direct access to the outer
rows of the J2 connector of the B-Size module (that is, VMEbus modules
that utilize the outer rows of J2) inside the adapter module. The short J2
cable makes internal connections between the P2 and J2 connectors of the
adapter module to allow for connections between the J2 connector of the
B-Size module inside the adapter module and the P2 connector of the
mainframe. Use this for VXIbu s modul es t hat uti li ze the outer rows of J2.
If your module has no outer row connections of J2, do not install either
cable.
See Figure 3-6 for the J2 connector’s pinout diagram.
all three may result if using the short cable in an adapter
module with a VMEbus module.
Install the J2 CableDo the following to install either J2 Cable:
On the C-Size VXIbus Adapter Module, remove the 7 Top Shield Retainer Screws
Selecting the TTL Trigger Direction (HP E1407A Only)
The HP E1407A C-Size Adapter Module has a switch that allows you t o set
the trigger signal direction of the TTL0–TTL7 Trigger Lines. Figure 3-7
shows that the TTL7 Trigger Signal comes from the B-Size Module, and
TTL0–TTL6 from the Mainframe's VXI Backplane. Use the illustra tion as
a guide to set the appropriate trigger directions for your application.
Figure 3-7. Selecting the TTL Trigger Signal Direction
Selecting the ECL Trigger Direction (HP E1407A Only)
The HP E1407A C-Size Adapter Module has a switch that allows you t o set
the trigger signal di rection of the ECL0 and ECL1 Trigge r Lines. Figure 3-8
shows that the ECL1 Trigger Signal comes from the B-Size Module, and
ECL0 from the Mainframe’s VXI Ba ckplane. Use the i llustrati on as a guide
to set the appropriate trigger directions for your application.
Figure 3-8. Selecting the ECL Trigger Signal Direction
The ribbon cable and a pai r of ju mpers connect the SUMBUS to the outpu t
connectors (i.e., to the B-Size Module). Use Figure 3-9 to disconnect
(i.e., remove the jumpers) or connect the SUMBUS.
The adapter module has no circuitry available to buffer the SUMBUS.
However, there is a breadboard area on the PC board in the HP E1407A
Adapter that allows you to add your own circuitry ( e.g., op-amps) to provide
buffering for the SUMBUS. The bre adboard area also incl udes connecti ons
to the ±12V Power Supplies.
You can add buffer circuitry either for SUMBUS signals coming from the
B-Size Module in the Adapter Module or from the Mainframe’s VXI
Backplane. Use Figure 3-9 to select the appropriate jumpers for your
application, and to locate the breadboard area.
