Agilent E2251A - Manual

10 Step 1. Remove the Carrier Shields 1. Remove the four screws securing the Carrier top and bottom shield. 2. Remove the screw securing the PC board to the bottom shield. 3. Set the screws and shields aside for later re-assembly (Step 6). Note Some earlier carriers did not have the screw securing t...

11 Step 2. Determine M-Module Layout 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 ...

12 Step 3. Set the Logical Address for each M-Module Each VXI module or M-Module in a VXI system must have a unique logical address. The logical address is used by the VXI resource manager to identify instruments. When the logical address of a module is set to a direct multiple of 8 (such as 8, 16, ...

13 Setting the Addresses As shown below, the E2251A has six logical address switch banks, one for 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 logica...

14 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 conne...

16 Step 6. Reattach the Carrier Shields 1. Carefully place the place the PC board on the bottom Carrier shield. Align the mounting holes and secure 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...

17 Step 7. Install Carrier into C-Size VXI Mainframe WARNING To avoid possible electrical shock, make certain that power is removed from the VXI mainframe, all field wiring, and external devices connected to the VXI mainframe. 1. Set the Carrier Extraction 2. Slide the Carrier into any slot (except ...

18 Step 8. Connect Field Wiring to Front M-Modules 1. Refer to “Assembling the M-Module Field Wiring Connector” on page 21 for information on assembling the connector and hood. 2. Attach assembled connector to M-Modules. 3. Tighten mounting screws to secure connector to the M-Module.

19 Step 9. Installation / Operational Verification 1. Turn on the VXI mainframe and use the VXI plug&play Soft Front Panels (SFP) to verify installation and operation of the M-Modules. The SFPs are supplied on the CD ROM accompanying your M-Modules and Carrier. The SFP is an MS Windows ® applica...

20 Removing M-Modules from the Carrier WARNING To avoid possible hazardous electrical shock, remove power from the VXI Mainframe, all field wiring, and external devices connected to the VXI mainframe. 1. Remove all field wiring connectors from the front-mounted M-Modules of the E2251A. Refer to “Ste...

21 M-Module Field Wiring Information The following section provides a brief, summary of the field wiring for each Hewlett-Packard M-module. It includes a connector pin-out table, a simplified schematic, and a connector drawing. For additional information about a specific M-Module, refer to the respe...

26 E2261A Quad RS-232 Interface Wiring Information Note: If you use the optional E2261-61601 cable, you must remove the cable hood if you install the E2261A in either of the two internal slots of the E2251A Carrier. The figure on the next page shows the cable wiring for making your own cable. Serial...

28 E2270A 16-Channel Form A Switch Wiring Information MAXIMUM VOLTAGE/CURRENT: The maximum voltage that may be applied to any connector on the E2270A, E2271A, or E2272A is 200 VDC, 125 VAC rms, or 175 VAC peak. These limits apply only if the product is installed in a humidity-controlled (<60% RH)...

These limits apply only if the product is installedin a humidity-controlled (<60% RH) environmen...

31 Configuring the E2272A The following figure shows the two jumper positions for the E2272A. In position A , the M-Module is configured as a dual 8-to-1 multiplexer. In position B , the M-Module is configured as a single 16-to-1 multiplexer. B Single 16-to-1 Multiplexer Position A Dual 8-to-1 Multi...
