data format of 8 data bits with 1 start bit, 1 stop bit, and no parity check. Note that the data format is reserved
to be compatible with other brand‘s communication port, it should not be modified if only OMR is used in a
system. The baud rate can be configured according user’s requirement.
Setup Equipments
Only screw driver is used to open the case. Software, power supply, and wiring are not necessary.
Setup Procedure
