Installation
Handling:
The DDA-3010 contains static sensitive devices and proper static free handling precautions should be observed.
When individual modules are stored, they should be placed in antistatic bags and proper antistatic procedures should
be followed when inserting and removing cards from these bags.
Power:
Ensure that the voltage selection of the IRT mounting frame used to house the DDA-3010 and the local AC mains
supply voltage match and that the correct rating fuse is installed in the mounting frame power supply.
Earthing:
Chassis earth connection of the equipment mounting frame is via the earth connection on the three pin (IEC) AC
mains supply inlet. This is a safety earth and must be connected.
Installation in frame or chassis:
See details in separate manual for selected frame type.
Links LK1 is factory set for a contact make to ground on signal failure at SK10 pin 2 on the rear panel, move LK1
from the normally closed (N/C) to the normally open (N/O) position for a break to ground on loss of signal loss or
loss of lock.
Links LK2 is factory set for a contact make to ground on signal failure at SK10 pin 3 on the rear panel, move LK2
from the normally closed (N/C) to the normally open (N/O) position for a break to ground on loss of power.
Link LK4 in the OUT position sets the card for 140 Mb/s operation and is indicated by the ‘140’ front panel LED
(yellow).
Link LK4 in the IN position sets the card for 155 Mb/s operation and is indicated by the ‘155’ front panel LED
(green).
The presence of either a 140 Mb/s or 155 Mb/s locked signal is indicated by the ‘SIGNAL’ front panel LED (green).
The presence of the in5 Vdc supply is indicated by the front panel LED (green).
It is recommended that unused outputs on the rear panel be terminated with 75-ohm termination plugs.
