To Install the HVCX1 Option
CAUTION
When the HVCX1 option is used, the I/O lines are hardware configured as either
inputs or outputs. The hardware and software configurations for the input and output
ports must agree. The Digital488/80A unit is protected from configuration conflict,
but the I/O lines will not respond properly.
Note:
If disassembly or disconnections are necessary, first turn off the power, next disconnect the AC
power line, and then any other cables, prior to disassembly.
1. When the input and output port configurations on the HVCX1 option are complete, record the settings
on the
Digital488/80A HVCX1 Configuration Record
supplied with your user's manual or provided in
Appendix A of this manual.
2. Turn off the power. Next, disconnect the AC power line cord, and then all other test cables from the
unit.
3. Place the unit on a flat surface. Remove the four screws on top of the case and remove the top cover.
4. Locate the two DIN-96 connectors on the HVCX1 board labelled J1 and J2, and the two DIN-96
connectors on the Digital488/80A main board labelled J4 and J1.
Note:
If the HVCX1 option was not factory installed, the DIN-96 connectors have a jumper board
plugged into them. Remove the jumper board.
5. Hold the HVCX1 board upside down, with the label FRONT toward the front of the Digital488/80A
and the label REAR toward the back of the Digital488/80A.
6. Line up the J1 DIN-96 on the HVCX1 board with the J4 DIN-96 on the Digital488/80A main board.
Line up the J2 DIN-96 on the HVCX1 board with the J1 DIN-96 on the Digital488/80A main board.
7. Press down the HVCX1 board gently but firmly to plug together the DIN-96 connectors. Be careful not
to bend any DIN-96 connector pins.
8. Carefully reassemble the unit.
Note:
For re-assembly, first reconnect the AC power line, and then any other cables, prior to reapplying
power to the entire system.
