2) Configuring the Server

The following section refers to the runtime configuration file for the GL200 device communication server, which

can be found in the GTS Installation directory at "dcservers/dcserver_qgl200.xml".

2.1) Changing the Server "Listen" Ports.

The ports on which the GL200 DCS listens for incoming data packets is specified on the "ListenPorts" tag:

<ListenPorts

tcpPort="37493"

udpPort="37493"

If required, the "listen" port can be changed to fit the requirements of your runtime environment. The script

programmed into the GL200 device will also need to be configured to transmit data to the same port as the server

used to listen for incoming data packets.

The "listen" ports must be open through the firewall in order for the remote device to send data to the GL200

server.

If packet acknowledgment is required, any acknowledgments sent by the server back to the remote device must

be sent from the same IP address to which the remote device sent it's data packet. If your server responds to

more than one IP address, then the GL200 server listener must be bound to the same IP address/interface used

by the remote tracking devices. This is set in the top-level "dcservers.xml" file, on the "DCServerConfig"

tag, "bindAddress" attribute.

2.2) Setting the "Unique-ID" Prefix Characters.

The Unique-ID prefix characters can be set in the "UniqueIDPrefix" tag section:

<UniqueIDPrefix><![CDATA[

gl2_

qgl2_

imei_

]]></UniqueIDPrefix>

These prefix characters are used to 'prepend' to the IMEI number reported by the device to look up the owning

Account/Device record for this device. For instance, if the IMEI number is "123456789012345", then the system

will search for the owning Device using the following Unique-ID keys, in the order specified:

gl2_123456789012345

qgl2_123456789012345

imei_123456789012345

123456789012345

Note that the '*' character by itself indicates that the system should look up the IMEI number without any prefixing

characters.
