1 EMI ground This terminal is connected internally to the PIFA’s
frame and to internal protective circuits. It should be
connected to the ground rail with a separate, heavy
gauge.

screen of the communication cable, which in turn
should be grounded at one point at least.

20 0 V Power supply 0 V. The 0 V-connection is normally
grounded at the supply source, so as to define the
potential to earth reference and to compensate for
disturbances and transients from I/O signals.
21 TxD2 See “The RS232 Port” on page 2. RS232 connection, Port 2
This connection is galvanically
insulated from the internal circuits.
GND2 is the signal zero. Use screened
cable and earth it at one point.
