The optional internal GSM modem offers the advantage of being internally powered and is fully
compatible with the unit. It does not require any special setup.
The 1800/1900 MHz magnetic antenna together with its 2 meter cable is supplied with the internal
modem option. The antenna is intended to be placed outside of the genset panel for the best signal
reception.
The module requires a GPRS enabled SIM card for full functionality. Voice-only type SIM cards will
usually not function properly.
Please refer to GSM Modem Configuration Guide for more details.
