Type: Installation and User Guide

Kamstrup GSMD 2G is an advanced module designed for mounting in OMNIPOWER electricity meters. It supports 2G (GPRS) technology and offers seamless integration within the meter's module area. With its plug-and-play installation, you can quickly set up the module and benefit from its clear signal strength indication. The GSMD 2G module provides flexibility with its pulse input feature and enables remote meter reading and signal strength monitoring via SMS. It also boasts an internal antenna and the option to mount an external antenna (sold separately) for enhanced signal reception.

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 (=sttus#).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.

2 Mounting GSMD 2G module

GSMD 2G module, rticle number 681Cxxxxxxxx, is supplied vi the module connector nd cn be

connected with n externl ntenn.

2.1 Mounting procedure

1 Dismount the top cover of the meter.

2 Insert SIM crd (see ”SIM crd”, pge 8).

3 Plce the module in the meter’s module re (plese check tht the eight module pins re ll

plugged in).

4 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).

5 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 GSMD 2G module”, pge 9.

6 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 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 and 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 Signal strength indicator

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.

3.2.5 Error indication

If one of the diodes ﬂshes, it mens the following:

1 SIM crd protected by  PIN

2 No SIM crd

3 Missing network registrtion

4 Communiction error with modem

Note: All diodes turn off after 10 minutes

They can be reactivated by pushing the button.

4 SIM card

4.1 Mounting the SIM card

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 GGSMD 2G module

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 card requirements

The SIM crd must fulﬁl the following requirements:

GSM/GPRS, DATA/SMS, Mini-SIM (standard size)

PIN code must be disabled, no voice and no pre-paid card can be used.

5 Mounting of external antenna (to be ordered separately)

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 External antenna on GSMD 2G module

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
