I am having issue in powering up RV50X GSM Modem. I am doing the same connections as they are given in the data sheet.
Pin 1 red = + of the battery
Pin 2 black = ground ( -ve of the battery)
Pin 3 ignition = + of the battery
Pin 4 GPIO = ground( -ve of the battery)
When I make a connection, Power led doesn’t turn on.and I also measured the voltage on the GSM modem power cable it is 24Vdc. So my input is according to the data sheet between 7Vdc to 36Vdc.
I have tried calling sierra yesterday whole day for technical help, but no response. I have 3 GSM Modems and all have the same issue. Can I get a help on this issue.
Any response will be appreciated.
