RS232C/RS485 Converter FC2A-MD1
The RS232C/RS485 converter FC2A-MD1 is used to convert data signals between EIA RS232C and EIA RS485. This
converter makes it possible to connect a host device with RS232C interface to multiple
MicroSmart
CPU modules using
one cable.

Transmit Data Indicator
Goes on when RS232C transmit data (pin #2) is on
Receive Data Indicator
Goes on when RS232C receive data (pin #3) is on
RS232C I/O
Connect to the RS232C por t on the computer
AC Adapter Jack
Frame Ground
Note:
Connect 24V DC to POWER and – terminals or connect an AC adapter with 9V DC, 350mA output to the AC
adapter jack.
Note:
The FC2A-MD1 contains a 220
Ω
termination resistor on the RS485 line, eliminating the need for an external termi-
nation resistor. To use the internal termination resistor, connect terminal T to terminal B. When the termination resistor is
not needed, disconnect terminal T from terminal B.
