3.2 CONNECTING GENISYS II TO EXTERNAL SERIAL DEVICES
3.2.1 General Description of GENISYS II Serial Ports
The GENISYS II controller board has four independent serial ports. The GENISYS II application
program determines the function of each of these ports. Each port may be designated as a
GENISYS protocol master or a GENISYS protocol slave. The function of serial ports may be
designated in any combination.
The four serial ports support three different hardware interface standards. Ports 1 and 2 support
an RS-485 hardware interface, while port 3 supports an RS-423 interface, and port 4 supports an
RS-232 interface. These standards (RS-485, RS-423, and RS-232) define only the characteristics
of the hardware interface. They define characteristics such as interface voltage levels, whether
