16i/18i/21i
The external modem is connected with the reader puncher interface of CNC.
PC and CNC can be connected via Reader/Puncher interface.
The cable for the connection must be the one for modem connection
(so-called “Straight cable”).
Additionally, please follow the manual of the modem.
(Note)+24 and +5V are output to the RS-232C serial port of CNC.
Moreover, +24V is output to the 25pin of the reader puncher interface relay
