Installation
Caution
The CardModule is shipped in a
protective anti-static bag. Please take
suitable precautions to avoid static
discharge onto any part of the PCB or
components when handling module or
serious damage could result.
Each Card Module is supplied with a rear
connection panel and two mounting screws.
Please follow the following procedure for
installation of the card module into the Series 5000
Card Frame.
a) Select a slot in the card frame where the
CardModule will be located
b) Remove the blank connection panel from the
rear of the rack (if fitted)
c) Install the rear connection panel using the
screws supplied. Do not tighten the screws fully
d) Slide the card module into the card frame and
carefully check the CardModule easily
connects to the rear connection plate. The
card should fit easily and should not require
excessive force to insert, if you feel any
resistance, there could be something wrong
with the rear connection panel location. Do not
try and force the connection. Remove the rear
connection panel and check alignment with
the CardModule.
e) Insert and remove the CardModule a few times
to ensure correct alignment and then tighten
the two screws to secure the rear connection
plate

Settings and Control
The D AD 5220 has an integrated micro-controller,
which enables the module to be configured and
controlled locally via the dip-switch, or from remote
when using one of the optional controllers and
control software.
Once set, all settings are automatically saved in
non-volatile internal memory. (Flash ram) The
module will always recall the settings used prior to
power down.
The module local configuration are performed
using a 4-position dip-switch on the front edge of
the module (please refer to figure 2).

Reference Manual D AD 5220 Version2.0
Page 17
Switch Settings
Below the switch settings for the 4-position dip-
switch are defined. Please refer to figure 2 for the
location of the switch.
Factory Preset Condition
The D AD 5220 is delivered with stored presets for
the following functionality:
Local Adustment enabled
Dual 1 > 4 mode
No further adjustments are needed if this is the
functionality desired.
Switch Setting Function
ON Enable Local Adjustment
1 OFF Disable Local Adjustment
ON Dual 1 > 4 mode
2 OFF Single 1 > 8 mode
ON Not Used
3 OFF Not Used
ON Not Used
4 OFF Not Used

Reference Manual D AD 5220 Version 2.0
Page 18
Switch Function Detail
All settings are stored in Flash Ram inside the
module (see Auto Store section in this manual).
Settings will be recalled on power up.
Dip Switch 1
This switch enables local control using the dip-
switches. ON enables local control and makes
selections on the dipswitch active, and OFF
disables local control (locking out any local
changes)
Note.
When Switch 1 is initially switched to ON, the static
settings currently set on the dip-switches may not
reflect the actual configuration stored in the
module. This is because all settings can be
changed from the remote control system or via the
Service Adapter. This overrides the local dip
switches regardless of Switch 1 ON/OFF setting. To
ensure the module reads the local dip switch
settings it is recommended to toggle Switch 1 ON-
OFF-ON before making any local changes to the
dip switches.
Dip Switch 2
This switch selects the mode of operation for the
module. ON selects dual 1 into 4 mode where each
individual AES input is distributed to four outputs.
OFF selects 1 into 8 mode where input AES in 1 is
distributed to all 8 outputs.
Dip Switch 3
This is not used
Dip Switch 4
This is not used

Auto Store
If no parameters are changed for 10 seconds then
the current settings will be written into flash memory
automatically, this can be seen by the channel
condition LEDS flashing yellow four times.
Alarm/LED Status Indicators
The D AD 5220 module has LED indicators that serve
as alarm and status indication for the module.
Function is described below.
The Indicators are found on the front edge of the
module PCB. Status indicators are at the top and
the alarm LED is at the bottom. (Figure 2)
Channel Condition Indicators
Channel Status LED`s are provided on the module
front edge, which has three color states. LED 1 is for
AES in 1 and LED 2 is for AES in 2.
Note. When in 1:8 mode LED2 is always OFF
