Need to connect new HDTV to older surround system

[rray2051]

Bought a new Samsung 50" (UN50MU6070F) and need to connect to my older surround system (HARMON-KARDON AVR 135) which has no HDMI connections. Any suggestions?

From the specs, it looks like they both support Digital Optical, so you would need a TOSLINK digital optical to run out from the TV and in to the receiver.
