Telecontrol converter for pulse-code and pulse-length modulated protocolsTechnical Details
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.
