Touchscreen Cabling; Trackball Cabling; Process Cabling - Honeywell Enhanced Micro TDC 3000 User Manual

2.7.10 Touchscreen Cabling

The optional Touchscreen and Trackball are not to be used together on the same US, so
they share the same connector (J1) on the EPDGP I/O card. When the Trackball or
Touchscreen is selected are bulkhead connected at the transition panel (see Figure 2-7).
1. The cables from the optional touchscreen pass through the clamps in the left location
marked TOUCHSCREEN on the lower transition panel in Figure 2-5, and are to be
connected to the EPDGP I/O card in slot 2 as shown in Figure 2-6.
2. Plug the large connector into J1, marked TOUCHSCREEN or TRACKBALL in Figure
2-6, on the EPDGP I/O card and the small connector into J4, marked POWER in
Figure 2-6. The EPDGP I/O card may have to be partially or completely pulled out to
make these connections. Use proper board handling precautions, including a grounded
wrist-strap, to extract the card. Use care not to disturb or dislodge existing cables and
then firmly reseat the card.
3. Using a cable-tie (51190879-001) on each cable, fasten the cables to their strain-relief
clamps on the upper transition panel.

2.7.11 Trackball Cabling

The cable from the optional trackball is to be connected to the lower transition panel at the
left location marked
Trackball
(2) on the connector. In accordance with the user's preference, place the trackball either to
the right or left side of the keyboard.

2.7.12 Process Cabling

It is not necessary to connect process cabling to the Enhanced Micro TDC 3000 Control
System before you turn power on and make the preliminary checks described in Section 3.
Skip this section and go on to subsection 2.8 if the process connections are not yet available.
Two UCN taps must be mounted within 5 cable meters (15 cable feet) of the UCN connectors on
the transition panel (see Figure 2-5). Before you continue with these cabling instructions, be
sure you have mounted the UCN trunk and taps in accordance with instructions in the UCN
manuals listed in subsection 1.5. Also, be sure the taps and drop cables have been tested and
clearly marked "A" and "B" to avoid miswiring.
Use only the UCN drop cables to and within the towers of this equipment. UCN trunk cables are
too bulky and lack the appropriate electrical characteristics for proper operation.
