I have a gm862 50-pin board and i power it up and ground it and using a RS-232 shifter I connect tx of the shifter to rx of the gm862 and visversa. When i type in in hyperterminal AT I get nothing i see tx on the shifter blink but thats it I dunno what to do any tips?
The GM862 is DCE. It transmits on the pin labelled “RX” and receives on “TX”.
Also, you will need to pull ON/OFF low for one second to turn on the module.

Oh Ok yeah what i had done before your reply is i connected Tx-O from the shifter to gm862 Tx-I and Rx-I from the shifter to Gm862 Rx-O once i did that I started to see what I was typing in hyperterminal but i will wait and i would not get no ok respond after. The status led now blinks when i puch the button and if i push it again it turns off. So now ill try what u said to see if I get any respond thanks…
It still dont want to work i get no respond from the Gm862.
I got it to work finally!!!
Any details on what you did to get yours working?
Mine doesn’t work and I’m pretty sure I’m doing it right.
