9. CONNECTION TO FANUC I/O Link
200
Modules can be connected in the same way, regardless of whether you are
connecting the basic module to an expansion module or connecting two
expansion modules. Connect the modules by using 34–pin flat cable
connectors as shown in the figure below. Ensure that all 34 pins at one
end of the cable are connected to the corresponding pins at the other end;
e.g., connect the A1 pin to the pin having the same designation (A1) at
the other end.

NOTE
Modules need to be spaced at least 32 mm apart, in which case a flat cable of about 20 mm
in length is required. To install modules further away from each other, the cable length will be
20 mm plus the extra distance. Note that the maximum length of a flat cable is 300 mm. To
ensure adequate ventilation, install the modules in such a way that the flat cables lie on top of
them. The basic module has a vent at the top (as indicated by the dotted lines in the above
figure). When connecting modules, install expansion modules so that the flat cables do not
cover the vent, as shown in the above figure.
Therefore, for direct connection to the connection printed circuit board, expansion modules are
installed to the right of the basic module on the installation plane. For installation using DIN
rails or screws, expansion modules are installed to the left of the basic module on the installation
plane.
