Grow GM66 - 2. Communication Interface; 2.1 Serial Communication

5
2 Communication interface
GM66 can receive database, control module and set functional parameter by TTL - 232.
2.1 Series Communication Interface
It’s default and common to connect module and mainframe(such as PC, POS) by series
communication interface. Make sure communication parameter for module and mainframe are same,
then it will communicate smooth and correctly.
Series Output
TTL-232 is used for series interface which suitable for most system. Required change-over circuit
for RS-232.
Default Parameter as formForm 2- 1. Only Baud Rate can be changed.
