Installing and Connecting the Unit
15
To connect the PTZ camera control lines
Connect the PTZ camera control lines to either the RS232 or RS485 spring clamp terminal block
connectors. For more information on how to use the spring clamp terminal block connectors,
see
Connecting Leads to a Spring Clamp Terminal Block
(page 21).
Note:
The serial communications parameters between the PTZ camera and the encoder must be
configured through the setup process described in the
HTML Edition Units User’s Guide
.
Warning:
The RS-232 standard specifies a maximum open-circuit voltage of +/- 25 volts.
Exceeding this voltage can cause permanent damage to the unit.
The RS485 standard specifies a maximum voltage of +12V and -7 volts. Exceeding
this voltage can cause permanent damage to the unit.

Connecting the Analog Video Output to an Analog Device
The analog output video contains the composite video from the camera combined with On-Screen Display
(OSD) overlays such as detected objects, tracking boxes and trails, time stamp, alarm, camera status, etc.
These OSDs can be enabled and customized using the unit’s web interface. Connect the VIDEO OUT
connector for each channel to separate analog output devices.
The analog video output can be monitored using an analog monitor or recorded on a digital video recorder
(DVR). For more information, refer to the
HTML Edition Units User’s Guide
.
Note:
The analog video output signal of the unit is disabled by default.
You can enable
it by using
the unit’s web interface.
To connect the unit analog video output to an analog device
Using a 75Ω video coax cable with BNC connectors, connect the VIDEO OUT of the unit to the
analog device video input (for example, the VIDEO IN of a monitor).
Note:
Make sure the ioimage unit and the external analog equipment support the same video
standard (PAL or NTSC).
3.2.9
Connecting the Unit to Receive Alarms from External Devices (Alarm Inputs)
The alarm input interfaces on the unit are used to receive four alarm signals from an external device, such
as sensors, doors, and so on, enabling the unit to trigger automatic responses. The alarm input includes two
dry terminal contacts. See Figure 5: trk100/trk100d Back Panel (page 2) and Figure 7: trk200 Back Panel
(page 6).
Warning:
1.
Only dry contacts can be connected to the unit’s alarm input terminals.
2.
Disconnect power from the unit before performing the following procedure.
