Connect the Philips HD 11 XE Ultrasound Machine audio output to the Vascular Research Tools gating box.

The Philips HD 11 XE Ultrasound audio output is via an 1/8 inch stereo jack(exactly like connecting speakers to your home pc). The signal was  split, using an 1/8 inch female-female to male/ Y adapter. One of those outputs was converted to mono with an 1/8 inch adapter. Using the same(now mono) output, an RCA was connected to an 1/8 inch mono adapter. Finally, a BnC was connected to the RCA adapter, completing  the signal connection from the Ultrasound to the signal booster.

Everything was bought at Radioshack. This should work for the IU22 model as well.
