Developer Board and Interfaces Description
3.4.2.1 RS232
The 9-pin, D-type RS232-1 serial port (J350) is the primary interface to the g20 UUT. The UUT RS232 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 pin names are DTE-oriented.
Note
3.4.2.2 USB
The USB interface (J300) operates according to the g20 UUT configuration. The Developer Board has a complete USB trans-
ceiver circuit to support USB communications for g20 units that do not include a USB driver of their own. The Developer Board
USB interface can be overridden manually when using a g20 unit that does include its own USB driver interface.
