CONNECTIONS AD1416,AD1416L
CONNECTIONS
Video Inputs
The AD1416 has 16 CAMERA input BNC connectors with
75-ohm terminations. The AD1416L model has 32 paired
CAMERA BNC connectors, of which 16 are for video inputs
and 16 are for passive looping outputs. If any video input is
not looped through the AD1416L to other units, a 75-ohm
BNC terminator must be connected to the matching connector.
The video input connected to Input 1 has an on-screen
designation 1; the video connected to Input 2, the on-screen
designation 2, etc. Use a good grade of 75-ohm cable with
BNC connectors.
Video Outputs
Two MONITOR video output BNC connectors are provided.
Output A is the camera video sequence interrupted by holds
and alarms. Output B provides output of continuous
sequencing of the cameras, unless altered by the initial setup as
shown on page 2. Each output must be terminated in 75 ohms.
Use a good grade of 75-ohm cable with BNC connectors.
Alarm Inputs
Alarm signals are provided by closures to ground on the 20-pin
Alarm connector, J1, located on the rear panel. A mating plug
is supplied. Table 2 shows the Alarm Connector Pinouts.

Note: Use Class 2 wiring only for alarm connections.
Cascading Connections
Two switchers may be cascaded together to provide 32-input
switching. An 8-pin modular phone jack, J3, is provided on
the rear panel of each switcher for cascading. Connect these jacks
using 8-pin modular phone plugs with pin-to-pin connections.
For cascade operation, order Kit AD1416CK which contains a
communication cable and panel labels for cameras 17 through 32.
The lower of the two BNC connectors for each MONITOR
output is used for cascading video. Connect Output A of the
master unit to Output A of the slave unit and Output B of the
master unit to Output B of the slave unit using a good grade of
75-ohm cable with BNC connectors. Either or both of the
upper sets of MONITOR output BNC connectors may be used
for display of Outputs A and B.
Auxiliary Inputs/Outputs
Connections for other signal inputs and outputs are provided
by the 12-pin connector, J2, on the rear panel. A mating plug
is supplied. Table 3 shows the Auxiliary Connector Pinouts.
Table 3 - Auxiliary Connector Pinouts
Pin Function Pin Function
1 Ground 7 Relay (Common)
2 Camera ID 0 8 Relay (Norm. Open)
3 Camera ID 1 9 Relay (Norm. Closed)
4 Camera ID 2 10 Tape
5 Camera ID 3 11 Ground
6 Logic Out 12 Ground
Note: Use Class 2 wiring only for auxiliary connections.
The Camera ID pins provide the 4-bit binary equivalent of the
on-screen camera number for use with system display panels,
computerized system controls, etc. Logic high (5.0 V) is 1.
Logic low (0.7 V) is 0. Camera ID 0 is the low bit.
The Logic Out pin provides a logic-level output of the alarm
status. It is high (5.0 V) while no alarms are present and low
(0.7 V) while alarms are present.
The Relay pins (Normally Open, Normally Closed) provide
access to isolated, Form C, SPDT contacts which are activated
while an alarm is present. They can be used to actuate a user-
supplied VCR or alarm devices. These contacts are rated at:
Voltage - 100 mv minimum, 24VAC maximum.
Current - 100 ua minimum, 1 amp maximum.
The Tape pin accepts a negative 4 to 8 Vp-p, 0.4 millisecond
synchronizing pulse, for frame locked switching or recording,
from a Time Lapse VCR or from another external source.
Power Connection
Depending on the model, the AD1416/AD1416L operates with
either 120 VAC or 230 VAC. This unit is shipped with a
pendant cord for use with an electrical outlet. Insert the
appended 3-wire cord and plug in the required power source.
AD1416, AD1416L - 120 VAC, 50/60 Hz.
AD1416/X, AD1416L/X - 230 VAC, 50/60 Hz.
