ELECTRICAL I/O
(See Table 5)
Electrical I/O terminals are available from a
breakout board inside the PulseTrack 2 control
Panel (see Figures 6 and 7). For maximum noise
immunity all electrical I/O should be run in cable
having a foil shield with an overall braided shield.
Special noise reduction connectors have been
provided at the top of the PulseTrack 2 control
panel for routing of all electrical I/O (see Figure
8). Signals specific to an individual rotator can be
routed through that rotator's ATM connector, while
common signals can be routed through the SYS
connector. To make electrical I/O connections
using these connectors, perform the following:
1. Remove the cable grommet hardware from the
desired connector (see Figure 9A).
2. Route desired length of cable through connector
housing and mark 1" span of cable that passes
through connector housing as shown in Figure
9B.
3. Remove cable and strip marked 1" section to
the cable braid.
4. Slide the cable grommet hardware onto the
cable in the order shown in Figure 9A.
5. Route the cable back through the cable housing
and make the appropriate I/O terminal connections
(see Table 5).
6. Tighten the cable grommet ensuring the grom-
met spring makes 360
°
contact with the exposed
cable braid.
7. For maximum noise immunity, connect the braid
of the cable to earth ground at the end opposite
the control panel.
