Features
Peripheral bus
(Tool bus) Supports high-speed communications, so this communications
mode is normally used to connect to the CX-Programmer.
• Supports only a 1:1 connection.
• When the FQM1 is connected, the CX-Programmer can recog-
nize the baud rate and make the connection automatically.
Host link (SYS-
MAC WAY) This communications mode is generally used to connect to a
host computer. Both 1:1 and 1:N connections are supported.
• Host link communications are relatively slow compared to the
peripheral bus mode.
• The Host Link mode supports connections through modems or
optical adapters, long-distance connections using RS-422A or
RS-485 communications, and 1:N connections.
