Remove the two T20 TORX screws and lockwashers
holding the Option 300 assembly to the left-hand side panel
(as viewed from the rear of the instrument).
Lift up carefully on the left side of the assembly and
remove the assembly from the three large tabs holding it
on the right side. It is not necessary to disconnect the two
cables going to the assembly.
Lay the assembly on its back to the right side of the chassis
and place the three small tabs on the back side of the three
large tabs into the three slots on the assembly deck.
GPIB Connector Installation Procedure
1 Remove the GPIB Cover Plate using a T20 TORX screwdriver.
2 Insert the GPIB Connector through the connector hole on the
rear panel.
3 Use a 7mm spin-tite to install the two supplied Hex-head standoffs
and lock washers. Tighten the two standoffs securely (do not over-
tighten).
4 Connect one end of the supplied 16-pin ribbon cable to connector
J901 on the motherboard chassis.
NOTE Be sure the non-insulated side of the pins on the cable is facing
the pins in the motherboard connector to provide electrical
contact.
5 Connect the other end of the ribbon cable to J1 on the GPIB
printed circuit assembly.
6 Re-install the Option 300 Internal Battery DC Power Assembly (if
removed). Be sure the cables are connected.
7 Re-install the cover by performing the cover removal procedure
(Preliminary Steps 1-4), in reverse.
