CHAPTER2
InstallingtheRTU
13
To establish the data connection between the A850 and the A753,
certain steps must be executed. These steps are split into two
sections:
1. Configuring the GPRS parameters
2. Configuring the TCP parameters
 CAUTION Parameter values are case sensitive. Be sure to correctly spell the
values of the GPRS parameters and use the appropriate case.
Misspelled names/entries will cause the RTU to not connect to the
GPRS network and/or A850.
ConfiguringtheGPRSParameters
Enter the GPRS parameters for your cellular network provider to
configure GPRS operation of the A753. The GPRS configuration
commands are:
GPRSAPNSERV "[servername]"
where [servername] is the name of the network
provider's GPRS access point name (required)
GPRSAPNUN "[username]"
where [username] is the name of the GPRS user's name
for your network provider (sometimes optional,
depends on your provider)
GPRSAPNPW "[password]"
where [password] is the password for the GPRS user
(sometimes optional, depends on your provider)
The following examples show the GRPS parameters for an Austrian
mobile phone services provider:
GPRSAPNSERV "A1.net"
GPRSAPNUN "[e-mail]"
GPRSAPNPW "ppp"
ConfiguringtheTCPParameters
The A753 will connect to the A850 only if the following TCP connection
parameters are set properly:
GPRSCONNADDR "[a850-ipaddress]" "[portnumber]"
where [a850-ipaddress] is the IP address of the A850
the A753 has to connect to and
[portnumber] is the port number where the
communication with the gateway will occur; the IP
address parameter must be in decimal dotted notation,
e.g. 198.182.196.56 (required)
