e=STRK%3AMEBIDX%3AIT> &ssPageName=STRK%3AMEBIDX%3AIT

 

They arrived after 2 months.

 

I have all the components ready to mod.

 

Just 1 detail I need help with please.

 

From
http://www.crompton.com/hamradio/usb_fob_modification/usbfob_interface.pdf

For the heartbeat LED "to USB FOB green LED anode, cut cathode lead of
onboard green LED"

 

As my soundcard do not have a green LED.

 

Is this LED driven form pin 12 (LED0) from the CM108?  

 

I am planning to connect a 390 ohm resistor and LED to the correct Pin on
the CM108 for the heartbeat.

 

Kindest Regards
