Power connection
Do not connect mains to the desktop power supply before connecting the power supply to the
router.
Connect the DB9 female connector from the desktop power supply to the main unit. Tighten the screws to
assure a proper contact. To connect mains to the desktop power supply you need a mains cord with IEC
320 connector.
The AV0110 is normally delivered with the desktop power model
AC ±15V / 10W.
Upon customer
request, AV0110 can also be delivered with
DC ±15V / 30W
, which may be fed by a 36 – 72 VDC mains
power source. A Frame mounted power supply solution is also available.
Please refer to the latest VikinX Product Catalogue for power supply types, or call Network Electronics
ASA for this information.
If an external power supply is used the AV0110 requires ±15V DC with a minimum current of 200mA.
The following pin-out is used on the DB9 connector:

Signal termination
It is not necessary to terminate unused video outputs.
The DIP switch beside the video input gives the possibility to terminate the video input direct on the
AV0110. In position UP (75) the video input of the AV0110 is terminated with 75 ohms and the LOOP
output is not in use. In position DOWN (HI-Z) the video input is not terminated, the LOOP output can be
used.
If the video signal is routed from the LOOP output to other devices, the end of the loop chain have to
have an internally terminated device or a termination plug. To assure correct frequency response a
precision termination plug with 0,1% tolerance must be used.
