WARNINGS (contd.)

In a cleanroom environment, some switch modules (such as the E2270A, 2271A, 2273A, etc) are capable of switching voltages that could
cause bodily injury or death to an operator. Special precautions must be adhered to (discussed below) when applying voltages in excess
of 60Vdc, 30Vac rms, or 42.4 Vac peak for a continuous, complex wavef orm.

Module connectors and test signal cables conn e cted to them must be made NO N- a cce ssi ble to an op era t or w ho ha s no t been tol d
to access them: It is a supervisor’s responsibility to advise an operator that dangerous voltages exist when the operator is instructed to

access connectors and cables carry in g t hese voltages. Making cables and connectors that carry hazardous voltages inaccessible is a
protective measure keeping an operator from inadvertant or unknowing contact with these harmful voltages. Cables and connectors are
considered inaccessible if a tool (e.g., scre wdriver, wrench, socket, etc.) or a key (equipment in a locked cabinet) is required to gain access
to them. Additionally, the operator cannot have access to a conductive surface connected to any cable conductor (High, Low, or Guard).

Assure the equipment un der test has a dequate insulatio n between the cable connections and any opera tor-accessible parts (doors,
covers, panels, shields, cases, cabinets, etc.): Verify there are multiple and sufficient protective means (rated for t he v ol tages you are

applying) to assure the operator will NOT come into contact with any energized conductor even if one of the protective means fails to
work as intended. For exam ple, th e inn e r side of a case, c a bine t, d oo r, c ove r, or p ane l c an be cov e red with an in sula tin g m ate ria l as well
as routing the test cables to the module’s front panel connectors through non-conduct ive, flexible conduit such as th at used in electrical
power distribution.

Strain Relief Plates

1. Identify the positions your M-Modules will occupy in the E2251A Carrier. The Carrier can hold up to
six M-Modules only if neither of the modules in the two interior slots (M4 & M5) require external
cabling. If one or both interior modules require external cabling, the bottom-front slot (M0) must be left
unused to accommodate the wiring; strain relief clamps are provided. The following figure shows the
common M-Module layouts.

11

Step 3. Set the Logical Address for each M-Module

Each VXI module or M-Modul e in a VXI system must have a unique l ogical
address. The logica l address is used by the VXI resource manager t o identify
instruments. When t he logica l addres s of a module is set to a direct multiple
of 8 (such as 8, 16, 24, ... 256), that module is considered an “instrument”.

An instrument's seconda ry address (used to pro gram the module from GPIB)
is derived by dividing the instrument logical address by 8. For example, a
logical address of 24 is a secondary address of 03.

Guidelines for

Determining Logical

Addresses

Note Multiple-module Scanning Voltmeter or Switchbox instruments are not

The E2251A comes from the factory with the M-Module logical address

instructs the Carrier to ignore that slot and the Carrier does not report it to
the VXI system resource manager.

You must
in the E2251A Carrier.

If you are using an E1406 Command Module set M-Modul e add resses to a
multiple of 8 (i.e., 8, 16, 24, 32, . . . 256). Do not set any M-Modul e logical
address to the same value as any ot her M- Module or any o ther VXI mod ule
in the system. You can use up to 31 M- Modules (up to se ven Carr iers ) with
an E1406 Command Module or 255 M-Modules (up to 51 Carriers) with
embedded controllers, VXLink, or MXIbus controllers.

supported with M-Modules on the E2251A Carrier. Multiple-module
instruments can only be created using standard B- or C-size VXI modules.

Unused slots on the E2251A Carri er should hav e their lo gical addr ess set to
0 (zero). With the logical address set to 0, the Carrier disables the circuits
(interrupt, reserved memory, etc.) for that slot.

1

In the E2251A M-Module Carrier, logical address 0

set the logical address switches for each M-Module installed

1. Note that in a standard VXI system, logical address 0 is reserved for the VXIbus command module / resource

manager. On the E2251A Carrier however, logical address 0 causes the Carrier to disregard that M-Module
slot.

Addresses

As shown below, the E2251A has six logi ca l ad dress switch banks, one f or
each M-Module slot. You must set the logical address switches for each
M-Module installed in the E2251A Carrier.

A logical address switch bank contains eight individual switches. To
determine the logical address, add together the decimal values of the
switches that are set (posi tion 1 = set, 0 = not set). For example , in the figure
below, switches 4, 5, and 6 are set, t he other switch es are not set. Th e logical
address is the su m of t he decimal values of th e set switches: 16 + 32 + 64 =

13

Step 4. Install M-Modules onto the Carrier

1. For internally-mounted M-Modules (slots M4 and M5) see Step 5, next page.

2. Install RFI Dress Panel (p.n. E2273-04301) on each of the front mounted M-Modules. Dress panels act
like a gasket and minimize RFI. Make certain the M-Module-to-Carrier connectors line up properly.
Make certain the M-Module standoffs are aligned over the screw mounting holes.

3. Secure each M-Module to the Carrier (from the back side) with four M3x5 mounting screws
(p.n. 0515-0372, with captive lock washer) supplied with M-Module. Open handles on Carrier to install
screws for slots M0 and M3 M-Modules.

4. Install blank Dress Panel (p.n. E2251-04301) over each unused front panel slot to minimize RFI.

2. Align M-Module on Carrier.

3. Secure M-Module with
four M3x6 screws.

0515-0430

Do not remove
these screws
if removing
M-Module.

1. Install E2273-04301
Dress Panel on M-Module.

4. Install E2251-04301 Blank
Dress Panels on Empty Slots.

If necessary, slightly crimp Dress Panel with pliers so it stays attached to Carrier front panel.

Caution Static Electricity. Use anti-static techniques when installing/removing M-Module.

Use care when installing M-Modules onto the carrier connectors. The Carrier and
M-Module connectors ARE NOT keyed; it is possibl e to misalign an M-Modul e and
connect it to the wrong connectors. APPLYING POWER TO A MISALIGNED
M-MODULE WILL DAMAGE OR DESTROY THE M-MODULE AND THE CARRIER.

14

Step 5. Connect Field Wiring to Slot M4 & M5 M-Modules

If you installed M-Modules on either or both of the interior slots, the following instructions describe how to
secure the field wiring. If you did not install an M-Module in slots M4 or M5, skip this page and go to Step 6.

1. Cover the M0 2-row connector strip with provided Pin Protector/Cover (p.n. 1252-8273). This pin
protector protects the field wiring from chafing against the connector pins.

Note: Do not install the plastic cable hood (see page 21) on the field wiring connectors for the two internal

M-Modules. Do not install the RFI dress panels on the two interior M-Modules. If an RFI dress panel is
already installed on an M-Module, it must be removed. They are not needed and may interfere with
installatio n of the top shield.

2. Holes are provided in the Carrier for cable ties to secure the field wiring cables.

3. Install cable clamp plates (p.n. E 2251-01203) on top si de of PC boa rd. Secur e the cabl e clamp ( but do not
overtighten). Both clamps are required to prevent damage to PC board.

4. To minimize RFI, install a dress panel (p.n. E2251-04301) over the front panel M0 slot position. Have
the dress panel machined or punched to allow the cable to pass through. Machine the cut as small as
possible; large enoug h for the cab le and opt ional gro mmet (t o preve nt chaf ing) bu t ti ght to minimize RFI.

Step 6. Reattach the Carrier Shields

1. Carefully place the place the PC boar d on t he bot tom Carrier shie ld. Align the mou nting holes an d secu re
with the mounting screw.

2. For modules mounted in the interior slots (M4 & M5), make certain their field wiring is not pinched.

3. Position the top shield and align the mounting holes. Install four screws securing the top and bottom
shields.

4. Attach supplied M-Module labels to the Carrier top shie ld and the RFI Dres s Panel to iden tify M-Modu le
installed in the Carrier.
