USB interface connection issue

[geoffsearle]

I have recently purchased the usb interface to use with an AOR AR8600.  For the connection from the receiver to the interface, I have an 8-pin mini DIN for the receiver output, connected to the 3.5mm stereo jack that came with the interface.  I have pin 2 (discriminator output) of the DIN connected to both tips of the 3.5mm jack, and pin 8 (ground) connected to the base of the jack. 
The usb interface appears to be operating (led working) but no signal in pdw when pager signals are being received, the meter in pdw just flickers constantly.
Any advice? Have I connected the cable incorrectly?
Thanks, Geoff

After email contact, it appeared that the AR8600 detector output on pin 2 only is only enabled in NFM, while Geoff was using WFM for the pager signals. Mode changed and all working great.
