The connector's references have the following meanings:
[1]
TX Data In. Logic level 0 - 5 V. Data incoming under RS232 format with
1 start bit, 8 data bit, 1 stop bit.
The start bit is given by the transition high-low (5v-0v)
[2]
XTR analogic output.
Output analogic signal with approx. 0.5 Vpp in presence of a modulating signal. Should any useful
signal not available, an inchorent noise, with p.p. level greater than the signal itself, must be
present. D.c. level about 1.8V.
present. D.c. level about 1.8V.
[5] RX Data out.
0 - 5V logic level. Outgoing data under RS232 format, same as for the input data.
Usually, the logic level is high (5V) but it goes down
(0V) at the start bit.
[6] Carrier Detect.
Normally high (5V) it goes down in presence of a received radio frequency. There is no difference
between useful signal and noises, therefore it is a non selective chanel occupation signal. The
minimum information level varies from -96dBm at the maximum sensitivity, therefore it is not safetly
usable if the receiver is demanded to operate anyhow at its maximum sensitivity.
usable if the receiver is demanded to operate anyhow at its maximum sensitivity.
[7]
CTS : not in use in this version.
[8]
Auxiliary LED. It shows an Rx/Tx activity. It is the pilot signal of the internal LED
[3], [4] GROUND
[10] 5V DC
In the 5V supplied module this is the stabilized voltage input, while in the 12V supplied module it is
used as output channel to supply the integrated circuit of the W232 ADAPTER.

All configuration changes, by means of the dip switches, must be carried-out when the module is switched
off.
