10.5.5 3-9V Configurable Signals
Voltage range DC: 3-9 V configurable, only one voltage, called the signal supply is configured
for all these signals.
These signals supply an alternative data interface to RS232 to operate with radio/modems
which have logic level types of serial interface.
The signal supply itself is also available on pin 22.
Max output current for all lines is 10 mA.
10.5.6 RS232 Signals
Conforms to RS232 standard.
