However, the maximum pulse transmission distance for the manual pulse
generator is 50 m. Taking this into consideration, the cable length may
be extended to:
38.37 m (when two generators are used), or
25.58 m (when three generators are used).
Modules can be connected in the same way, regardless of whether you are
connecting the basic module to an extension module or connecting two
extension 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.
