RS-232 wiring - Port1 and handshaking signals connected
A typical connection between the Port 1 of the radio modem and the PC serial port (RS-232)
using the handshaking signals is depicted in the schematic below.
FUSE = 1 A slow (+6 … +30 V assembly) or 2.5 A slow (+3 … +9 V assembly)

RS-422 wiring
FUSE = 1 A slow (+6 … +30 V assembly) or 2.5 A slow (+3 … +9 V assembly)
If the transmission lines are long the receiving end of the lines must be terminated using a
separate termination resistor (typical values range from 100 -120 ohm depending on the
characteristic impedance of the transmission line).
