Communication Interfaces
The G30 Developer Board includes four serial interfaces ( Figure 2-12 ):
•
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
Table 2-4 .
Note: The RS232-1 connector pin names are DTE-oriented.
RS232-2
The 9-pin, D-type RS232-2 serial port (J330) is used for data logger when G30 adapter is used.
Note: Only the G30 adapter supports Data logger. If G30 with 70 pin connector model is used,
data logger is not applicable.
