4.2.1 Type

First of all, the HelloDevice Pro Series and the serial device must agree on the serial communication
type, which is one of RS232, RS422, RS485 echo mode or RS485 non-echo mode. The HelloDevice
Pro Series serial ports are configured for RS232 communication as a factory default, but they can also
be configured for RS422 and RS485 communication. To change the serial communication type, set up
the mode in the Type menu. See Appendix B for serial port connections due to the Type setup.
The HelloDevice Pro Series supports two types of RS485 communication – echo mode and non-echo
mode, which are both two-wire mode. In RS485 echo mode, all data sent to the serial port are
received back from the serial port automatically and compared with the data sent for the data integrity
while there is no action of receiving-back in non-echo mode.
