Page 4: Description
Internal antenna. • The GSM7i module differs from earlier GSM modules in that it can only be placed in ”J” meters, i .e . the Kamstrup electricity meters that have internal supply for the module . Application With the module GSM7i, the metering point is future-proofed since the module supports GSM, GPRS and SMS. -

Page 8: Mounting
2 .1 Mounting order 1. Dismount the top cover of the meter 2. Place the GSM7i module in the meter (please check that the eight module pins are all plugged in) 3. Insert SIM card (see paragraph 2.6.1, page 13) 4. -
Page 9: Start-Up Sequence
2 .2 Start-up sequence 1. Immediately after start-up, all the Signal indicator diodes and the test diode switch on briefly (see the following figure). 2. The two Signal indicator diodes at the bottom flash until the module has been initialised correctly (approx. 1 min.). When the diode at the bottom stops flashing, the module has been connected to the network (after approx. -
Page 10: Signal Test
2 .3 Signal test Five LED’s have been mounted on the GSM7i module to indicate the current GSM signal strength. Immediately after starting up the module, it will try to connect to the GSM network, and the signal strength indicator will be activated (see paragraph 2.4, page 11). -

Page 13: Sim Card
The unit can be ordered with the SIM card mounted from the factory. Please check that the card has been inserted. The telephone number of the card appears from a label on the GSM/GPRS module. Kamstrup A/S cannot be held responsible for theft and misuse of SIM cards from GSM7i units. -
Page 14: Sim Card Requirements
2 .6 .2 SIM card requirements The SIM card must fulfil the following requirements: GSM/GPRS, DATA/SMS-9 .6 . kb V110, PIN code must be disabled, no voice and no pre-paid card can be used . 2 .7 Mounting of external antenna (to be ordered separately) Connect the external antenna to the connector on the module. -
Page 15: Activating The External Antenna
2 .7 .1 Activating the external antenna External antennas with DC resistance between the inner and outer conductors of 10K ohms or less are detected automatically. This applies to the following antennas: Mini Triangle antenna (order no. 6699448) • Triangle antenna (order no. 6699407 or 6699408) •... -

Page 17: Mounting Status/Pulse Input
2 .8 Mounting status/pulse input The status/pulse input can be used to read the status of a potential-free contact or as pulse input from e.g. a water meter. If it is used as pulse input, the pulses will be counted in the pulse register of the electricity meter. Note that the electricity meter must be configured to receive pulses before the incoming pulses are registered. -
