Quick guide
1 Red the signl strength on the module’s Light Emitting Diodes (LEDs) (min. two LEDs must be
switched on).
2 If the signl strength is below 2, n externl ntenn must be instlled.
3 The externl ntenn must be plced in  loction tht optimises the reception of the signl.
Chnge the position of the ntenn until the best position hs been found.
4 Before leving the instlltion, test the signl strength by SMS (=signal#). Mke sure tht the
meter cbinet nd doors re closed before sending the SMS.
Tips
• Alwys instll n externl ntenn when the meter is instlled in  metl cbinet. The ntenn
must be plced outside the cbinet.
• Use qud-bnd GSM ntenns to optimise the performnce.
• Note tht fire doors, concrete nd metl pltes disturb nd weken the GSM signl.
• It is possible to order directionl ntenns for res with very poor signl conditions (plese
contct Kmstrup A/S for further informtion).
When plcing the meter
in  metl cbinet, mke
sure to plce the ntenn
outside the cbinet.
Mke sure to close ll
doors nd cbinets
before sending the SMS.

When plcing the meter
below the ground (e.g. in
 bsement), mke sure
to plce the ntenn
close to  window or
outside the building.

2 Mounting GSM8i 2G
GSM8i 2G, rticle number 6819xxxxxxxx, is supplied vi the module connector nd cn be
connected with n externl ntenn.
2.1 Mounting procedure
Dismount the top cover of the meter.
1 Insert SIM crd (see ”SIM crd”, pge 8).
2 Plce the module in the meter’s module re (plese check tht the eight module pins re ll
plugged in).
3 When ll green diodes on the module stop flshing, the signl strength cn be red on the
indictor (see ”Signl strength indictor”, pge 7).
4 If the signl strength is not cceptble, mount n externl ntenn. This requires tht the
internl ntenn is removed. See ”Mounting of externl ntenn (to be ordered seprtely)”,
pge 8 nd “Externl ntenn on GSM8i 2G”, pge 9.
5 Before leving the instlltion, check the signl strength by sending n SMS (see “SMS
commnds”, pge 11).
If the module does not indicte norml operting conditions (such s sufficient signl strength),
refer to ”Error detection help”, pge 10.

3 Light Emitting Diodes
The LEDs must provide the instller with sufficient knowledge to mke  good instlltion without
using externl tools.
Note: All diodes turn off after 10 minutes
They can be reactivated by pushing the button.

3.2.3 Connected to network nd to meter
The network to which the module is connected ppers from the diodes t the bottom of the
module. More thn one diode cn be turned on. Furthermore, the red METER diode flshes if there
is no connection between meter nd module. The GPRS LED is turned on if it hs been ssigned n
IP ddress.

3.2.4 Signl strength indictor
When the signl strength is less thn 2, n externl ntenn must be mounted. If n externl
ntenn hs lredy been mounted, it should be repositioned to obtin the required signl
strength.

4 SIM crd
4.1 Mounting the SIM crd
The unit cn be ordered with the SIM crd mounted from the fctory. Plese check tht the
crd hs been inserted. The telephone number of the crd ppers from  lbel on the module.
Kmstrup A/S cnnot be held responsible for theft or misuse of SIM crds from GSM8i 2G units.
When the SIM card holder is opened, the connection to the SIM card is disrupted.
When the SIM card has been inserted correctly, and the holder is closed,
the module starts automatically.
If the unit is supplied without  SIM crd, mke sure to insert one before using the unit.
The SIM crd holder is opened by pushing the bright holder bck nd crefully tipping it up. Next,
plce the SIM crd with the “cut-off” corner in the top left side nd with the contcts fcing the
PCB.
4.2 SIM crd requirements
The SIM crd 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.
5 Mounting of externl ntenn (to be ordered seprtely)
Externl ntenns with DC resistnce between the inner nd outer conductors of 1 K ohms or less
re detected utomticlly. This pplies to the following ntenns:
• Mini Tringle ntenn (order No. 6699448)
• Tringle ntenn (order No. 6699407 or 6699408)
• Directionl ntenn (order No. 6699456)

6 Externl ntenn on GSM8i 2G
Connect the externl ntenn to the connector on the module. Be creful to her  “click” before
the two connectors re connected correctly. Do NOT use ny tools in connection with the mounting
of the ntenn plug. Plce the ntenn cble inside the plstic frme of the module, nd led the
cble out through the cble chnnel t the bottom of the electricity meter.
It is importnt to notice tht the internl ntenn must NOT be mounted together with the externl
ntenn nd must therefore be removed.
IMPORTANT
To ensure tht the externl ntenn is mounted in such  wy tht it optimises the reception
conditions, observe the signl indictor on the module (see ”Light Emitting Diodes”, pge 6).
Chnge the position of the externl ntenn until the best position hs been found.
Mounting of externl ntenn
Remove the internl ntenn nd replce it with n externl ntenn
