2.1 Installation procedure
Turn OFF the power of the programmable controller, and mount the 232BD using the following procedure.
➀
Remove the panel cover from the top face of the main unit.
➁
Connect the 232BD to the board mounting connector provided on the
base unit.
➂
Fix the 232BD to the main unit using the M3 self-tapping screws
provided, fitting the mounting bracket and the round crimp-style terminal
with the ground cable as shown in the figure on the right.
Make sure that the crimp-style terminal is attached in the direction
shown in the figure on the right, and that the ground cable extends from
the unit shown in the figure below.

4. CAUTION FOR USE
1) When programming tool is connected the 232BD, do not use any other communication format or
parameters. If communication format or parameters is set, programming is not possible.
2) Only one programming tool (such as FX-10P , FX-20P , etc.) should be connected to either the pro-
gramming port or the port provided on the 232BD. If a programming tool is connected to both connec-
tors, the following may occur.
a) The program inside the programmable controller may not be consistent with the program inside
the programming tool. If the program is modified or the set value for the timer or the counter is
modified, a part of the program may be damaged and the programmable controller may
malfunction.
b) When the sampling trace function of the programmable controller is used from both ports, the
correct sampling trace result cannot be obtained.
