The number of cables required depends upon the cable type. One cable will be required for any cable type in
Table 4 except for Belden 9182. Because Belden 9182 contains only three conductors and six connections are
required, the choice of Belden 9182 will mandate the use of two cables.
Receiver Jack J4
Referring to Table 4, choose the appropriate cable type per the maximum operating distance between the
receiver (or distribution line control) and the VI 422.
The number of cables required depends upon the communications mode. Simplex communications require
the use of command lines only, which enable the Vi422 to communicate with the receiver but do not allow
receiver responses to be returned. Both response and command lines are connected for duplex mode, which
allows two-way communications between the Vi422 and receiver. For example, receiver alarm and
communication failure messages can display on the Vi422 local keypad LCD window if response lines have
been connected.
Choose either simplex or duplex operation and refer to the appropriate following section for the number of
cables required.

Because simplex mode requires only three connections (command lines only), dual cable is not required. One
Belden 9182 cable will be required to connect the receiver or distribution line control to the VI422 in simplex
communications mode. As shown in Table 4, these units may be located up to 25,000 feet apart using this
cable.
Both command and response connections are required for duplex operation. One cable will be required for
duplex operation for any cable type chosen from Table 4 except for Belden 9182. Because six connections are
required for duplex operation and one Belden 9182 cable contains only three conductors, two cables are
required if Belden 9182 is used.
Cabling to Printer Jack J5 and Host Computer Jack J6
The Vi422 rear connector panel includes two RS-232 ports. Jack J5 is used to transmit alarm reports to a
serial line printer. A host computer may be connected to jack J6. Vicon’s
software may be installed
on the host computer to provide a graphic means of controlling and monitoring camera stations. Alternatively,
the NOVA command set may be used to communicate with the V1422 without the
software, as
discussed in

Interface
X678: The host computer
may also be used to develop the configuration file.
One Belden 9536 cable will be required to connect the printer to the V1422 at an approximate distance of six
feet. One Belden 9536 cable will be required to connect the host computer to the
