FAQ Cable


What type of cable do I use for an external antenna?
Preferably use a 2 m extension cord to the GSM modem. Be aware that the signal strength weakens when using a longer cable.

Why will my PC not communicate with the unit?
Probably because the COM-port of the PC is not correctly noted in the program. Check which COM-port the PC uses in Windows control panel. Enter the installation program in ‘settings’/ ‘Modem/com. port’ and enter the correct value. (USB–>RS232 adapter often uses COM-port 4).

Which type of cable do I use to connect the PC with the unit?
Use RS 232 cable. An extension cord in which the wires go straight through.
