Connecting external devices
Digital Sprite 2 uses 485-Bus networking to interconnect Dedicated Micros
products and accessories. Storage devices can be connected to the SCSI port, and
telemetry cameras can be connected to the serial port. Devices that can be
connected to Digital Sprite 2 include:
Telemetry cameras
Storage devices
Ethernet networks
485-Bus devices
Audio devices
Connecting telemetry cameras
Digital Sprite 2 has in-built coaxial, serial (RS-232/485), and 485-Bus telemetry,
and DTMF telemetry using an optional telemetry adaptor. A remote keyboard is
used to control telemetry from the Digital Sprite 2.
The brand of telemetry must be set in the ‘Alarms and Presets’ menu.
Coaxial telemetry
Digital Sprite 2 currently supports Pelco Coaxitron* and BBV, using a BBV RX-100
p r otocol converter allows control of most major manufacture r’s domes.
*The Tour, Patrol, and Auto-pan features are not available when using Pelco coaxitron domes on a
Digital Sprite 2. If you require these features you must use either a BBV RX-100 protocol converter
or serial telemetry.
Serial telemetry
Digital Sprite 2 currently supports a number of domes using serial telemetry. Serial
t e l e m e t r y re q u i res a twisted-pair connection from the Digital Sprite 2’s serial port to
the dome. Serial telemetry can be star configured – from the Digital Sprite 2 serial
p o r t to each re c e i v e r, 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 2 is a 9-way male D-type connection. A 9-way D-
type female plug is required with the following pin-outs:
PIN RS-232 RS-485
1 nc Data A
2 RX nc
3 TX nc
4 GND GND
5 GND GND
6 nc nc
7 RTS nc
Viewed from the solder side. 8 CTS nc
9 nc Data B
nc = no connection
Note: The serial port must be configured for serial telemetry in the System
Options menu.
