This is nick, M2M system integrator in Azerbaijan. Does anyone use Xiamen four-faith M2M DTU(Modem) or 3G router before? Website : http://four-faith.com/En
is anybody can give me some suggestion?
One solutions of Vehicle Mobile ATM Tracking in Nepal, industrial cellular 3G WCDMA DUAL SIM Card router for Mobile Banking Vehicles.

Hello Ilgar aliyev,
First check signal strength by AT+CSQ,
return: +CSQ:**,## OK,"**,##" range from "8-31,99" menas it works normal
AT+CPIN? Check the SIM state
Return : +CPIN：READY OK (normal)
After check signal strength and SIM state are OK, we can send AT command as follow:
(1).Set two modem mode: ATS0=1 (Automatic response mode)
(2).B modem dial A modem by phone number: ATD13956555555 ,that means ATD+phone number.
If dial success,A modem will output “CONNECT” through COM,if A modem is busy,B modem ouput “BUSY” through COM.
After dial up success, two modem can go on data communication,you just need send data to Modem by COM.
When data transmission is over, both of two modem can hang up the connection, first input “+++”and Enter,after it return OK,input ATH command.
You can email me directly, i am not always online.
I have test Four-Faith F3423 Router in our project, Below is our test report:
Surprising for the money the device we tested was not too bad. The device was not as easy as the other two tested for setting up but once we understood what we had to do it was straight forward enough. It was tested at Whetstone on the Grab and Go machine where it held its connection for a week without fail. Signal was -105dbm (Poor). It is supplied with an external antenna on a 1 meter cable, however it uses standard SMA fitting for the antennas so if needed we can purchase high gain antennas from the UK to give better reception. We Fitted the device into Cummins where we were having real problems with the Raven XE and it has out performed its competitor. It has dropped its connection for over 24 hours (same as Raven) however it was able to regain it with out intervention where the Raven would need a human reboot. The Device also has remote modem administration where we can talk to the modem direct over the internet to change any setting without going to site (subject to connection).

Many of our vending machines use MDB protocol which means the vending machine communicates with the coin acceptor and bill acceptor by means of a MDB cable. The coin mechanism does and a data port where by a cable can be connected but this is configured by the manufacturer to their design. The coin acceptor we use is the NRI brand Currenza coin acceptor
