Communication Interfaces

The G30 Developer Board includes four serial interfaces
•
Primary RS232-1
Figure 2-12: RS232-1 Connector
This serial interface is described in the sections that follow.

RS232-1

The 9-pin, D-type RS232-1 serial port (J300) is the primary interface to the G30. The G30 UART
signals are active-low CMOS-level signals (0-2.7 V), which are converted by the Developer
Board to standard RS232 levels for PC communications. The RS232-1 Connector Pinout (J300)
is shown in
Note:

RS232-2

The 9-pin, D-type RS232-2 serial port (J330) is used for data logger when G30 adapter is used.

Only the G30 adapter supports Data logger. If G30 with 70 pin connector model is used,
data logger is not applicable.
