8.13.1 Components Required
The T2000-A66 kit contains the following components:
8.13.2 Fitting
Refer to Figure 8.13.1.
1 Remove the top cover of the radio by unscrewing the four cover screws, unclip the
D-range blanking plate in the rear of the T2000 radio, unscrew the logic PCB and
fold out.
2 T2000-A66 Mounting
Position the T2000-A66 PCB on the top side of the logic PCB, as shown, matching
P1 on the bottom side of the T2000-A66 PCB to the pads labelled ‘P1’ on the logic
PCB.
Use the two M2.5x10mm screws, nuts and shakeproof washers to secure in place.
Note:
The screws are fitted from the bottom of the logic PCB, and secured with the
nuts and washers on the top side of the UART PCB.
Torque the screws to 2.5in.lb. This ensures that the pressure connector, P1, makes
contact with the corresponding pads on the logic PCB.
Caution:
Over-tightening the screws will cause the T2000-A66 PCB to bend, result-
ing in possible track damage.
3 T2000 Data Interface Decoupling PCB Mounting
Fit the decoupling PCB to the T2000 chassis, guiding the PCB through the hole
provided.
Holes are provided in the T2000 chassis for the D-range locking screws. Use the
two black 4-40 Taptite screws provided in the kit to form threads.
Open the locking screw kit, discard the nuts, then secure the D-range using the
two locking screws and spring washers.
