TCT

Telecontrol converter for pulse-code and pulse-length modulated protocols

The protocol converter is equipped with RS232 interfaces which allow only asynchronous data traffic. A telecontrol transformer (TCT) can be used for coupling other protocols (for instance bit synchronous or pulse length modulated protocols).

The TCT is equipped with a µ controller responsible for converting data from or into the asynchronous format. The TCT does not assume a higher protocol function, telegrams are transformed on a one-to-one basis.

In order to prevent delays in receiving or transmitting, the connection towards the protocol converter operates at very high baud rates. Data transfer does not occur after a complete telegram has been received, but in smaller data blocks during reception.

The TCT is fitted with a serial RS232 interface in both directions as a standard. The serial interface towards the communication terminal equipment has been electrically isolated.
