Connected to DSR (pin6)
Serial data exiting the RF modem (to host)
Serial data entering into the RF modem (from host)
Can enable Power-Down on the RF modemy
Ground
Connected to DCD (pin1)
Provides RTS flow control or enables Command Mode
Provides CTS flow control
Optional power input that is connected internally to the
positive lead of the front power connector
* ? The ? ‘Pin ? Reference ? Name’ ? provides ? an ? associative ? tag ? that ? references ? commands ? used ? to ? define ? pin ? behaviors. ?
GPI ? stands ? for ?? General ? Purpose ? Input ?? and ? GPO ? stands ? for ?? General ? Purpose ? Output ? . ? As ? an ? example, ? the ? CD ?
command ? is ? used ? to ? define ? the ? behavior ? of ? GPO2 ? (DB ‐ 9 ? pin ? number ? 1). ? The ? ‘Pin ? Reference ? Name’ ? is ? the ? name ?
used ? when ? referring ? to ? XCite ? commands ? and ? parameters.
