Batboard

not that i need it right away but a while back i think it was for a m1225 or maybe sm50's i was told you need to jump a couple of pin's on the back of the comp .i've lost this info and i would like to retain it for future use ? i could be wrong on the model number for what radios are required if some one could enlighten me as to what 2 pin's need jumpering so i can make a note of it and not rely on my short term brain memory thanks Jhook ps this is on the 25 pin port of the computer i remember this much
