INSTALLATION AND OPERATION

the cable can be routed through any narrow places
(such as conduit) with the connector attached. Note
that bends and turns in a routing can sometimes be
difficult with an attached connector.

Figure 11 shows a typical test setup intercon-

nection diagram for the 3960 using a laptop PC
running WinMPC as the control point. Test cables
CTC-30 (115 V ac) and CTC-35 (24 V ac) are
available for this purpose.

Figure 16 shows four versions of a typical

system interconnection cable. Only 11 of the pin
locations on the connector body are used for the
two versions of the 3960 (24 V ac and 115 V ac).
Note that different pins are used for the power
input. Pin 12 is used for the line (hot) lead for 115 V
ac and pin 16 for one lead of 24 V ac.

Always pre-plan all system cabling before

starting an installation. Before a 3960 is bolted in
place, the system cable must be available to attach
to the pigtail cable at the mounting location.

Figure 16A is an assembly diagram for the

cable used between the 3960 and a typical junction
box having a terminal strip for all connections. This
cable has five stripped wire leads for the data
connections and also stripped leads for the ac
power plug BNC video connector.

Figure 16B is the assembly diagram for the

cable used between a 3960 and a typical junction
box. This cable has an ac power plug, BNC video
connector, and stripped leads for data connections
at the junction box.

Figure 16C is an assembly diagram for the

cable used between the 3960 and a junction box
having RS-232 data communications available. This
cable has an RS-232 to RS-422 converter wired in

for data communications with the RS-232 sources.
This cable also has an ac power plug and the BNC
video connector like the previous cable.

Figure 16D shows the cable wiring between

the 3960 and an optional Cohu Model 9300 Local
Control Panel (figure 15).

This panel is typically located in a nearby

equipment cabinet. It is used when an on-site local
control panel is desired for setup and maintenance
operations. This panel typically is installed in a
weatherproof cabinet located near the 3960 instal-
lation location. This optional panel can control
some functions of the 3960 without use of a local
laptop PC running WinMPC.

But a front panel BNC connector on the 9300

provides for connecting the RS-232 serial port of a
laptop PC to communicate with the 3960 using
WinMPC. When a 9300 local control panel is
installed at the 3960 site location, it becomes the
site address for the 3960. Any address pro-
grammed into the 3960 is not seen by the system.

Figure 12 is the assembly diagram for a test/

setup cable intended for use during setup and
maintenance operations of a 115 V ac 3960. This
cable is intended for use with the RS-232 output of
a laptop or other type PC; thus, an RS-232 to RS-
422 converter is required to communicate with the
3960 — which uses only RS-422.
