10.3 Physical Connection between PS2000A and Gateway
The PS2000A can be physically connected to the network server in RS-232, RS-485 or
Modem mode.
10.3.1 RS-232 Mode
Because there is not an RS-232 driver/receiver inside
the PS2000A, its input and output
signal can connect to the RS-232 port of the network server only after the level is
converted, as shown in Figure 20.

10.3.2 RS-485 Mode
Because there is no RS-485 driver/receiver inside the PS2000A, its input and output
signal is needed to be connected to the external RS-485 driver/receiver to connect to the
RS-485 port of the network server, as shown in Figure 21.
