+5 V Power supply
Connect the +5 V power supply at CN051 with the 5V jumper connection at the HDR051 connector. For all
internal operations, the +3.3 V power supply is generated by the mounted REG-IC. Ex3.3 V is not
required.

+3.3 V Power supply
C3.3 V power supply at CN052 with 3.3 V jumper connection at the HDR051 connector. All +3.3 V
power supply is provided from CN052.

SW001 is a reset switch for the DIR9001. External automatic power on the reset circuit is combined.

•

Connect the Toslink optical fiber cable connector at U001.

•

Connect the RCA Coaxial cable connector at CN001.

•

Optical input or Coaxial input must be selected by SW003 as OPT or COAX.
