DS2
Connecting external devices
The unit 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 ports. Devices that can be connected to unit include:
Telemetry cameras
IP Cameras
Storage devices
Ethernet networks
Alarms and Relays
Audio devices
485-Bus devices
Connecting telemetry cameras
The unit supports numerous protocols to control coaxial, serial (RS-232/485) and 485-Bus telemetry.
A remote keyboard can be connected to the unit to gain control of the telemetry function of the
connected camera, refer to Connecting 485 Bus devices.
The telemetry protocol type can be selected within the ‘Camera Setup’ and ‘Serial Telemetry Ports’
menus.
Coaxial Telemetry - Camera Setup Menu.
Serial Telemetry - Serial and Telemetry Ports Menu.
Serial telemetry
The unit currently supports a number of PTZ / dome protocols using serial telemetry, as well as
various RS232 matrix protocols.
Serial telemetry requires a twisted-pair connection from the unit’s serial port to the dome.
Serial telemetry can be either star congured (from the unit serial port to each receiver), or
daisy chained (each receiver is linked (looped) together), or a combination of the two. Therefore
each receiver needs to be addressed according to its camera number - Refer to the receiver
documentation for details.
Note:
Daisy chain telemetry conguration works up to 1000m (3200ft). The range using star
congured telemetry is reduced signicantly.
Serial telemetry connection
There are four, 9-Way male D-Type serial ports on the unit. Serial 1 and 2 are allocated as full RS-
232 only, with Serial 3 (BUS A) and 4 (BUS B) able to support RS-232, RS-422 and RS-485.
The 9-Way male D-Type has the following pin connections and RS-232, RS-422, RS-485 pin
allocation:
Note:
The serial telemetry connection must be congured for the correct type of dome in the
‘System Options’ menu.
