Wiring
Wiring is done with runs of cable for power, video and control. Optional wiring can be installed for the Relay
Output and 4 Alarm Inputs. All cables enter the Enclosure from the top on all pendant installations and through
the Conduit Fitting on all In-Ceiling installations. Refer to the Technical Information section for all electrical
requirements.
Power cables carry AC power and are usually a two-conductor type ranging in size from 20 to 12 AWG. The
power source is a Class 2 indoor/dry or Class 3 outdoor/wet rated type transformer. The leads should be
connected to Terminal Block 1 (TB1), pin 1 [H - (hot)] and pin 2 [N - (neutral)]. The size of the two-conductor
cable depends on indoor/outdoor application and cable distance as shown in Table 6 of the Technical
Information Section.
Video cables carry the composite video signal and Vicoax signals out of the Surveyor99 over coaxial cable. In
Vicoax mode, the video signal also carries the Control signals. The video cable should be connected to the
BNC female connector J1. Refer to the Reference section of this manual for information on recommended
cable types and maximum distances.
Control cables carry the NOVA/VPS digital signals and require individually-shielded twisted-pair sets. The
NOVA/VPS signals are carried via RS-422/485 protocol. The RS-422 protocol is used for single Camera
Dome applications. RS-422 signals are always active and do not have a tri-state (high impedance) state. The
RS-485 protocol is used for multiple Camera Domes in a daisy chain configuration. RS-485 signals are not
always active and do have a tri-state (high impedance) state. The type of cable required depends on the cable
distance and number of wire pairs within a cable, as shown in the Reference Section. These signals are
connected to Terminal Block 3 (TB3) or RJ-45 Connector J3. There can be a maximum of two Control cables
(twisted-pair sets), depending on the mode selected, Simplex or Half Duplex operation. Daisy chaining of a
Surveyor99 is not currently possible. Future revisions of Surveyor99 will support tri-state communication
signals in the RS-485 format. This will allow Surveyor99 to be daisy chained to any other compatible RS-485
device, including another Surveyor99. Refer to the Communications/Power Supply PC board Shield for signal
connection points.
Half Duplex:
This RS-422/485 protocol type allows two-way command and response flow between the
Surveyor99 and the control system that requires two individually-shielded twisted-pair cables.
Simplex:
This RS-422/485 protocol type allows command flow from the control system to the
Surveyor99 only requiring one shielded twisted-pair cable.
COMMAND IN (CIN):
A signal from the CPU that causes some function to occur in the Surveyor99.
RESPONSE OUT (RO):
A signal from the Surveyor99 to the CPU in response to a COMMAND IN signal or
triggered by an Alarm Input.
COMMAND OUT (CO):
A signal from the Surveyor99 that causes some function to occur in the CPU.
RESPONSE IN (RIN):
A signal from the CPU to the Surveyor99 in response to a COMMAND OUT signal.
