Connecting a Loudspeaker to the Unit
Use the supplied audio splitter cable to connect a loudspeaker to the unit and make announcements near
the camera from a microphone connected to the Video Management System PC. The audio output from
the unit provides Line Out levels. An amplifier must be used to drive the loudspeakers.
Figure 10: Loudspeaker Connection to the Unit
Note:
AUDIO OUT cannot be enabled from the unit’s web interface. Enabling AUDIO OUT from
the unit can be performed only by using a third-party Video Management System (not
Latitude) or using the ioimage API.
To connect a loudspeaker to the unit
1.
Connect the supplied audio splitter cable to the AUDIO IN/OUT port located on the front panel
of the unit. See Figure 4: trk100/trk100d Front Panel (page 3) and Figure 6: trk200 Front Panel
(page 5).
2.
Connect the Audio Output RCA connector at the other end of the audio splitter cable to the
input of the audio device (amplifier).
3.
Connect loudspeaker to the amplifier.
3.2.7
Connecting PTZ Camera Control Lines to the Unit
Connection of PTZ camera control lines to the unit can be made either with an RS232 or RS485 cable. If
RS232 is used, the connection between the unit and the PTZ camera requires use of an RS232 to
RS485/RS232 bi-directional converter. This converter should meet the following requirements:
Include a DCE/DTE switch
Support simplex and half-duplex communication
Support Tx ON from the encoder to the PTZ camera
Once connected, the camera can be configured in the unit’s setup software. This configuration allows PTZ
control of the specified camera using a remote PTZ controller. The connection capabilities of the encoder
provide up to two connections to the RJ45 port using the adapter cable. Connections can be either RS232
or RS485, depending on which cable connection you use.
