INSTALLATION INSTRUCTIONS

2.1
Requirements of Host Equipment
The Magic 485F25 Adapter can be plugged into any device with an RS232 port terminating in a
25 way 'D' type male connector (DB-25). If the host device is equipped with a 25 way connector,
it is normally male, and the Magic 485F25 Adapter can be directly plugged into this port.
The 485F9 Adapter can be plugged into any device with an RS232 port terminating in a 9 way 'D'
type male connector (DB-9).
2.2
Connections to the Magic 485F Adapter
Connections are made to the Magic 485F Adapter at each end. The RS232 connections are
automatically made when the Adapter is plugged into the port, and the RS422/485 data, control
and power connections must be made through a pluggable 8 way screw terminal connector
assembly at the free end.
RS422/485 Connections on 8 way Pluggable Terminal Strip
The DC power input, RS485 transmission turnaround external control signal and RS422/485
data signal connections are made via an eight way screw terminal connector. The supplied
connector can be unplugged from the Adapter for ease of making the cables without removing
the Adapter from the port.
The connections are compatible with other RS485 Adapters in the Amplicon range, and are
shown in Figure 2.2 below. The diagram shows the connector as viewed from the top face of the
Magic 485F Adapter. The abbreviated function names are printed on the printed circuit board
below the fixed part of the connector.
