I am currently using Serial communication, and I want to change it to Parallel communication. Is it possible?
STP-131supports both Serial and Parallel interfaces, but you should use the dedicated cables for STP-131. If you were using the serial communication, purchase the Parallel cable, and plug in the parallel cable to the port from where you unplug the serial cable.
* Changing from parallel to serial is also supported.
* You should use the dedicated cables in all cases.
