1. Introduction
1.1 General
The gACC-499E/U is specially developed for the so-called SME segment where the used gas meters or
gAVC 1200 can be read remotely to retrieve the actual meter readings. Essential is the use of optical
encoders with a NAMUR communication output. As a result, it is possible to perform a cyclic read-out of the
index value by using the IEC62056-21 protocol. Other communication methods are available on request. The
gACC-499E/U is available in mains power supply and battery power supply. The mains power supply version
can be used for short measuring cycles and frequently used communication, e.g. for feeding a web portal.
The battery power supply version is suitable for daily, weekly or monthly communication modes. In daily
communication, with good network coverage, the battery life span (2pack) will be approx. 6 years.
1.2 Basic construction
The modem gACC-499E/U consist of 2 main compartments whereby the largest compartment is equipped
with a mainboard on which the power supply terminals, inputs and the TC-65i or TC-65ix module carrier are
placed. The smaller compartment contains a multi-channel Zener barrier which complies with the ATEX
directive 94/9/EC for all possible input signals. The compartments are separated by a removable dividing
wall.
The Zener barrier EX-499-UW complies with an associated intrinsically safe apparatus in the form of a max.
5-channel Zener barrier. The number of channels depends on the application.
Normally the device is supplied completely configured, whereby the SIM card can be placed if requested by
the customer. The connection of the unsafe side is at the top of the Zener barrier performed by a plug
connection. The intrinsically safe outputs and terminals for the potential equalizing are located at the bottom,
so in the standard version in the terminal compartment of the housing.
The gACC-499E/U can be used for several applications whereby it can operate as a stand-alone data logger
for e.g. index readings of a gas meter with a NAMUR encoder, a simple pulse generator or as
communication unit for the gAVC 1200. For every application a specific configuration file is necessary. By
using an 8-pole DIP switch the device can be set to the desired application. Time windows can be applied to
let the gACC-499E/U login to the net at fixed intervals. After that there can be dialed-in by using a data
collection system. These settings are stored in a XML-file in the memory of the gACC-499E/U.
By using the gACC-499E/U in combination with an gAVC 1200 there will be a protocol conversion from
MODBUS RTU to IEC62056-21 performed. The specific settings of the gAVC 1200 can be performed in a
transparent mode via the gACC-499E/U. The configuration program of the gAVC 1200 can make a
transparent connection by using a modem, whereby all the parameters can be read. With the availability of
metrological rights all parameters can also be programmed.
The gACC-499 E/U can communicate data via the IEC62056-21 protocol where 3 main functions are
supported.
1. Billing data,
2. Load profile data
3 Time synchronization.
For this protocol is a separate detailed protocol description available (gAVC_1200_IEC62056-21.pdf). In
addition an access password (P1) can be used to prevent unwanted connections with measurement.

DIP switch function: Active at position ON
All switches are in OFF position at delivery,
xcept for DIP switch 7. This will save energy of the batteries.
The internal clock will keep running at normal operating mode.
2.3 Battery connectors
The gACC-499 E/U is equiped with 6 battery connectors.
These are divided into 2 groups.
MAIN POWER
Group1: Connector 1.1; 1,2; 1,3 and 1,4 Main Power
RESERVE POWER
Group 2: Connector 2.1; and 2.2 Back-up and clock power
When applying 2 battery packs, connector 1.1 is used for main
power, and 2.2 is used for back-up.

2.5 Power supply
2.5.1 Battery supply
The standard battery supply consists of 2 identical battery packs with each
pack containing 2 Lithium batteries connected in series. The operating
voltage is 7,2 Vdc. The battery pack that is connected to connector 1.1 will
be used first for the modem and the battery pack that is connected to
connector 2.2 will be used for the internal clock. After pack 1.1 is
consumed it will switch to pack 2.2. For certain applications additional
battery packs can be applied. These will be connected to connectors 1.2;
1.3 and/or 1.4.
An additional pack can be connected to connector 2.1 for extended back-
up.
Warning: Always use batteries of the same type

gACC-499E/U Communication unit
gACC-499E_U_Manual_EN.doc
When replacing battery packs in a normal operating state, a new battery pack can be connected to an
available connector, before removing the already placed battery packs. If the battery packs are totally
consumed and the device is no longer in operation mode, remove the empty packs before placing new
battery packs. When inserting new battery packs, always connect the first battery pack to Group 1 (e.g.
connector 1.1) and the second battery pack to Group 2 (e.g. 2.2). Do not forget to set the clock. (see chapter
6.0 The clock for setting the clock.)
2.5.2 Mains power supply
The power supply consists of a power module with an operating voltage
of 7,2Vdc. De power supply will be connected to Group 1 (e.g. connector
1.1). If required, a back-up battery can be connected to Group 2 (e.g.
connector 2.2).
The power supply module is equiped with a IEC mains power connector.
The supply of voltage of 85Vac to 230Vac can be connected to this.
The housing of the device is equiped with an additional cable gland.
Once the gACC-499E/U is provided with mains power an optionally
connected EVCD from Flonidan (gAVC 1200) can also be powered.
The supply voltage is 4Vdc and intrinsically conducted.
2.6 Modem Configuration
The configuration of the required information can be done by using a simple XML file which determines
which data in which format should be sent. This requires a configuration program which can be used to
configure the modem locally and remotely. For local configuration of the modem a special USB-config cable
is available.
2.7 The configuration IEC 62056-21
To read-out the gAVC 1200 with the IEC62056-21 protocol a special configuration file is required which
contains specified settings for the protocol. The configuration file is written into the modem. The settings for
the provider are limited to the name of that provider and for GPRS-connection also the APN-data. Instead of
the name of the provider, “home” may also be entered. This sets the provider of the used SIM-card as
default provider which excludes roaming into other networks. The server type must be set to LOCAL.
Please note the protocol settings for the gAVC 1200. It must always remain at 2400 Baud and 8N1 to
communicate with an encoder or an gAVC 1200.
It is also possible to configure the gACC-499E/U remotely by using the configuration program in combination
with a local modem. For this, the corresponding COM-port must be selected. By entering a modem init string
e.g. AT&FX1&K0DT the program knows that it should dial the number that has been entered at “Phone
number” via a modem. For local communication there should not be a modem init string entered.

GA-02.035-EN-30.05.17

gACC-499E/U Communication unit
gACC-499E_U_Manual_EN.doc
By clicking the symbol in the left upper corner a window will open which contains the special functions of the
program. At “Set Value” the index value of the pulse counter can be set to a start value (meter
synchronization) or to be reset. The “Name” must be entered as VB and the value as a decimal number.
The pre-setting of the index value can be done by using a config cable. If the modem is in “sleep” mode the
config cable must be plugged in the socket in order to activate it.
The modem will now come out sleep mode and will become active. At least 3 LEDs have to be on before a
value can be written. For battery modems this can be done by setting DIP switch 3 to ON. Make sure that
DIP-switch 3 is back in the OFF position before placing the cover. This is to save battery power.
The gACC-499E/U is equipped with a selection switch for the configuration. With DIP-switch 5 (to OFF) can
be chosen between the gAVC1200 application and (to ON) the Encoder application.
These functions will be described in more detail in chapter 2.13 The hidden functions.

general
confversion=”1”
This is the current configuration version. This can be increased by 1, and then with the
next data transmission the available data in the current interval will be sent.
loglevelstdout=3”
Specifies the level of logging. 0 is the highest level and 3 is the lowest level. A choice can
be made between 0, 1, 2 and 3. During normal operation level “3” is selected. This is only
used for communication analysis .
checkpwdlocal=”Y”
Enter =”N” or “Y”. N is the choice of not applying a password. When Y is entered, a
password is used to gain access to the gACC-499E/U.
readcfgallowed=N”
Enter =”N” or “Y”. Y allows reading of the configuration and when N is entered, it’s not
possible to read the configuration without a password
sleepallowed=”Y”
Enter “N” or “Y”. For battery powered devices the “sleep” mode can be suppressed for a
fixed time. This affects the battery life span.
battlifeoffset=”6”
This determines the number of months on which a low battery warning will appear before
the end of the calculated life span of the batteries. 0/12 can be entered
dualmainbatt=”N”
In case of application of a battery at Bat2 and Bat3 here should be an ”Y” entered.

daylight=”Y”
With mains powered or permanent powered modems an automatic reset must be
performed daily.. The time is entered at reset hour. This should preferably be done shortly
before the read-out takes place, in order to have the cache complete during read-out. The
daylight parameter ensures that summertime is applied.
device
The type of device is opened.
name=”gprs003”
The name of the device.

2.12 Configuration read-out
Reading out the configuration and configuration file can be performed by using a config cable or through a
modem connection. In case a password is required for reading out the configuration and configuration file
this can be entered at the “Password” field (below the “Baud rate” field). The activation of the password is
arranged in the configuration file. During read-out the user will be prompted whether to save the
configuration file or not.
At the end of the read-out the below dialog appears.
This dialog shows:
a. The field strength in dB
b. Software version and compilation date
c. Device time (current time)
d. TC65 version number
e. The setting of the DIP-switches (x = not linked to CPU; 0 = OFF and 1= ON)
f. IMEI number of the TC65 (This number can be copied to the clipboard for further processing.
This can be used to find the modem serial number in the list.)

2.13 The hidden functions
The configuration program of the gACC-499 has some hidden functions. The hidden functions can be used
by clicking on the icon in the left corner of the configuration program. The here shown functions can be
executed both locally by using a config cable and also remotely via a modem.
“about GACCconfig....”
Under “Settings” there is a dialogue in which a choice can be made to hide the passwords and to activate
summer / winter transitions.. This last function only affects the local readout of the cache memory of the
gACC-499E/U.

Encryption
Under “Encryption” there is a dialogue where the passwords can be encrypted and/or decrypted.
Set value
At “Set value” a pre-set index value can be entered for the logging of impulses of e.g. a gas meter. With this
function the index value of the gas meter can be synchronized with the commissioning of
the gACC-499E/U
Set time
At “Set time” the time of the connected PC can be written in the gACC-499E/U. It is important to check if the
time of the PC is the correct time before this is written into the gACC-499E/U. For more clock settings see
chapter 6..

IEC622056-21 Communication
With the configuration program it is possible to communicate through the IEC62056-21 protocol by using a
modem connection. In order to do this select “Start IEC” from the menu. The COM-port for the modem needs
to be set, a phone number must be entered and a modem init string must be specified.
At “Status” the status of the communication is continuously displayed as well as the ICT (Inter Character
Time).
At “Functions” the date can be read and/or set, de time can be read and/or set, billing data can be retrieved
and an interval for a load profile can be set in order to read it afterwards. The default interval which is
displayed by the configuration program is always the latest current day. The program locks the buttons while
performing the last chosen action. This will prevent that the current processes will conflict with eachother.
In the window “Results” the communication will be displayed.
Control cache file
With "Control Cache File" can be checked whether the cache is properly created and also displays the file
size.
