Commercial & Private IP Based Devices

IP Based Communications (GPRS or Private IP Radio System) Settings

The following INI settings should be used, when communicating via either TCP or UDP protocol on an IP based communications infrastructure regardless of how that infrastructure is established.  These setting exist (or should be added) to the [MDC] section of the INI file and will be required by both MDC Workstations and the MDC Controller.

[MDC]

COMTYPE=2     (2=TCP : 3=UDP)
CONTROLLER_IP=192.168.1.1
PORT_ID=777

The COMTYPE setting of 2 is used to indicate to the MDC software that the program should send and receive all data via a TCP connection based protocol.  The COMTYPE setting of 3 is used to indicate to the MDC software that the program should send and receive all data via a UDP connection-less protocol.  On all MDC workstation computers CONTROLLER_IP setting should be set to the fixed IP address of the computer serving as the MDC Controller (192.168.1.1 is the default address).  The PORT_ID should be set to the IP Port used by the software for communication between the MDC Controller and the MDC Workstation.  Port 777 is the default.  Please be sure to configure any network routers or firewalls to allow TCP/IP traffic to pass on the port defined in the Crimestar INI file.

* Although modern technology (such as a VPN) provide sufficient security, some states still prohibit the use of commercial carrier networks or Internet connectivity on any machine or network that is also interfaced to your respective state law enforcement or motor vehicle computer system.  When these types of security restrictions are applicable a private dedicated RF modem system may be a better communications choice.
