3. Installation Instructions

The Dennard drx400 requires all connections to the PCB to be made by the installer. These
connections are: power, video in, video out, and pan or auxiliary outputs. See Table for the correct
connections.
The Dennard drx400 is normally supplied pre-configured to suit the application for which it is
intended and this will be to control either a mains-operated pan & tilt head plus housing, or to
control a 24-volt pan & tilt head plus housing. The unit is suitable for 230 volt mains operation. As a
factory fitted option, the receiver can be supplied to operate from 24Va.c. or 110Va.c. This option
must be specified at time of order.
For mains-voltage panning heads, the 110V.a.c or 230V.a.c supply is made via the IEC socket J4.
(Note - For mains operations, J5 is linked Pins 1 to 4 and Pins 3 to 6.)
When using 24Vac heads, if the receiver is operating from a 110Vac or 230Vac supply either a
230/24V.a.c Kit or 110/24V.a.c Kit is used. The jumper fitted to J5 is removed and the plug supplied
with the kit is connected to J5. Fuse F2 is changed to the value shown in the table on 2.
Receivers operating from 24V.a.c can only operate 24V.a.c heads. No kit is required.
When operating from a 24V.a.c supply, power connection is by means of a screw terminal replacing
the IEC socket.
An 8 way DIL switch is provided allowing various options to be set as follows:-
SW1
Controls auto-iris remote control features (See Appendix for Lens List)
On - Cosmicar lens, 2.5 - 5.5 volts
Off - Seiko/Video Technical lens, 2.5 - 12 volts
SW2
Reverses zoom motor direction
SW3
Reverses focus motor direction
SW4
Reverses iris motor direction
SW5,6,7
Unused
SW8
Start receiver self test, see later in manual.
Two LED's (Error and Cable) are mounted on-board to give simple system status information. Their
functions are as follows:-
Cable LED
Regular Blinking - Telemetry and Sync signals OK
Blinking but mainly ON - No telemetry information from the transmitter
Blinking but mainly OFF - No sync information from the camera
Error LED
On - Transmission error (e.g. framing error, parity error)
Both LED's
Off - No power, or major PCB error
