Picture with no
control
If control is via a
drx100
protocol converter, check that the Green and Yellow
wires from the dome are connected correctly ie Green to C1 Yellow to C2.
If control is via RS485 check that the data connections are:-
Green Wire data - Yellow Wire data +
If control is via a 2055 co-ax (which has built in protocol converters), control is
"up the co-ax" but the address switches have to be set to suit the controller
protocol
See page 10 of the Type 2055 product handbook for settings
.

intermittent control
This problem is often due too to much or too little video gain.
If you are using the 2055 co-ax dome with built in protocol converters, video
amplification is accessed through the menu system. Open the
Technician Menu
enter the password
PIN
, select
Miscellaneous Services
from the next menu
then select
Set Video Amplification.
Adjust the gain to suit.
If you are using a 2055drx then the Video Gain can be found on the drx card
behind the BNC connectors located in the PSU box

This indicates that the 2055 software has detected an error. Before contacting
Dennard Technical on 01420 485713 the error display should be enabled as
this will help Dennard Technical to solve your problem. You need to open the
Technicians Menu
enter the password
PIN
, select
Enable /Disable Options
and select
Enable Error display.
A message will then appear at the bottom of
the monitor screen
On Baxall controlled
Domes, alphabet
menu pops up
when the joystick is
touched
This is because the Baxall controller has been configured to
ALTERNATE
mode
which is not supported by the 2055. Setting the dome to
STANDARD
mode with
Rx
set to
DC
will solve the problem.
On Dennard & BBV
controllers the
dome spins
continuously
Could be due to no dead band on the joystick caused by the joystick being off
centre on power up. Power the controller down then power up again ensuring
that the joystick is free to self-centre.
