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 BES-3232/75 is normally delivered with the desktop power model AC ±5V / 30W. Upon customer
request, BES-3232/75 can also be delivered with DC ±5V / 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 Triton Product Catalogue for power supply types, or call Thomson Grass Valley
for this information.
If any third party power supply is used the BES-3232/75 router requires ±5V DC with a minimum current
of 800mA. The following pin-out is used on the DB9 male power connector:
