INSTALLATION INSTRUCTIONS
480 SERIES
DINKY LINK™ INFRARED RECEIVERS
These small IR receivers have been designed for mounting in very small spaces. They may be mounted
under shelf edges, cabinet ledges, in wall speakers, etc. - anywhere an inconspicuous appearance is
desired. The high sensitivity of these receivers allows placement behind speakers grilles and still receive
IR commands up to 20 feet away. If longer range is necessary, a 3/8-inch hole must be drilled in the grille
to allow unobstructed entry of the IR signal. The model versions covered by these instructions are as
follows:
480B-00 Standard version, with black case. Has a 7 foot, three-conductor ribbon cable with stripped and
tinned ends.
480W-00 Same as the 480B-00 except with white case.
480B-30 Quick connect version of the 480B-00. 7-foot cable with 3.5 mm stereo mini plug for direct plug-
in to Xantech Connecting Blocks, such as the CB12, CB20, 789-44, 791-44, etc.
480W-30 Same as 480B-30 except with white case.
Each version in the 480 series has the same features and specifications as follows:
FEATURES
• Very small package, only 7/16" x 5/16" x 2-1/8".

PHANTOM POWER CONNECTIONS
Some existing installations may have only 2 wires (such as coax) going to a remote room. The 480, when
used with a 792-10 Power Module, may be connected for 2-wire phantom power operation as follows:
Additional 480's may be wired in parallel at the 3-terminal block, up to a maximum of three. More than this
may cause unreliable results.

CAUTION: With any of these systems, be sure the 781 power supply is plugged into an un-switched AC
outlet. This maintains the 480 system in "standby" operation so that power-on commands can be sent to
the controlled equipment.
