If TCP communication fails when a CTM-200 is reporting data to a server, packets are stored in non-volatile memory until the TCP connection is re-established, at which time the stored packets are forwarded. Storing of data is limited to the CTM-200 reporting system only and does not cover connected devices (laptops, etc) communicating via LAN/WLAN connections.

This provides support for different types of MODBUS Slaves (Serial RTU/ASCII and MODBUS TCP over Ethernet). This feature is integrated into the CTM-200 reporting system. Reports can be triggered based on MODBUS register values or events. This support also has the ability to log data on internal MicroSD storage media (file based reporting system).

Digital outputs can now be pulsed for a duration specified in 10ms increments. This may be used for driving buzzers, lights or latching relays with a remote command or from within a script.

J1939 parameter support has been enhanced to include p42(ASR/ABS), p43(seat-belt status) and p44-p45(light status). Note: these parameters are not supported on all J1939 vehicles; refer to vehicle manufacturer specifications for details.
