232 Interface
Serial communication interface is usually used when connecting the engine to a host device ( like PC ,
POS ). However , to ensure smooth communication and accuracy of data , you need to set communication
parameters ( including baud rate , parity check , data bit and stop bit ) to match the host device .
The serial communication interface provided by the engine is based on TTL - level signals . TTL - 232 can
be used for most application architectures . For those requiring RS - 232 , an external conversion circuit is
needed . The conversion circuit is available only to some models .

requirements .
