Connecting External Devices; Connecting Telemetry Cameras - Dedicated Micros digital sprite Einrichtungsanleitung

Connecting external devices

Although Digital Sprite can be used as a standalone digital multiplex recorder, its
flexibility allows additional accessories and storage devices to be connected to
build much larger systems.
Digital Sprite uses c-bus networking to interconnect Dedicated Micros products
and accessories. Devices which can be connected to Digital Sprite include:
Telemetry cameras
Storage devices
- Removable disks - Zip ® , Jaz ®
- RAID
- Digital tape storage - DDS, VXA
Ethernet networks
c-bus devices
- Alarm modules
- Remote keyboards
- Video switchers
If you do not require any of the above devices to be connected to Digital Sprite,
move on to 'Configuring Digital Sprite' – Page II.

Connecting telemetry cameras

Digital Sprite has in-built coaxial, serial (RS-232/485), and c-bus telemetry, and
DTMF telemetry using an optional telemetry adaptor. A remote keyboard is used
to control telemetry from the Digital Sprite.
The brand of telemetry must be set in the 'Alarms and Presets' menu.
Coaxial telemetry
Coaxial telemetry does not require any connections other than camera connections.
Digital Sprite currently supports Pelco and BBV, using a BBV RX-100 protocol
converter allows control of most major manufacturer's domes.

Serial telemetry
Digital Sprite currently supports serial telemetry for JVC and Ultrak domes. Serial
telemetry requires a twisted-pair connection from Digital Sprite's serial port to the
telemetry receiver. Serial telemetry can be star configured – from the Digital Sprite
serial port to each receiver, or delta configured – each receiver daisy chained
together, or a combination of the two. Each receiver needs to be addressed
according to its camera number – consult your receiver documentation for details.
Serial port connection
The serial port on Digital Sprite is a 9-way male D-type connection. A 9-way D-
type female plug is required with the following pin-outs:
nc = no connection
Note: The serial port must be configured for JVC or Ultrak telemetry in the
System Options menu.
c-bus/DTMF telemetry
Dedicated Micros telemetry receivers can be controlled using c-bus or DTMF
(telephone tones). When using c-bus telemetry the receiver is connected directly to
the c-bus connectors on the back of the unit. When using DTMF telemetry a
telemetry adaptor (TAD3) is required to convert the telemetry commands into DTMF
tones. DTMF and c-bus telemetry can be configured in a star or delta configuration.
