Central unit
Connectors and connection
Connector X1 - for the Keyboard connection
SUB-D type 25-pin female connector to connect the central unit with the keyboard.
FAGOR AUTOMATION provides the cable necessary for this connection. This cable has two 25-
pin male connectors of the SUB-D type.
Both connectors have a latching system by means of two screws UNC4.40.
It is a parallel connection, 1 with 1, 2 with 2, 3 with 3, etc. The cable shielding is welded onto the
metallic caps covering both connectors.
Connector X2 - for Fagor monitors
25-pin male connector of the SUB-D type to connect the central unit with the monitor.
Fagor Automation provides the cable necessary for this connection. This cable has two 25-pin
female connectors of the SUB-D type.
Both connectors have a latching system by means of two screws UNC4.40.
It is a parallel connection, 1 with 1, 2 with 2, 3 with 3, etc. The cable shielding is welded onto the
metallic caps covering both connectors.
Connector X3 - RS232
It is a 9-pin SUB-D type male connector to connect the RS 232 C serial port.
The cable shield must be connected to the metallic hood at each end.
All the pins of this connector are opto-isolated.
Cable length.
EIA RS232C standards specify that the capacitance of the cable must not exceed 2500pF; therefore,
since average cables have a capacitance between 130pF and 170pF per meter, the maximum length
of the cable should not be greater than 15m (49ft).
Shielded cables with twisted-pair wires should be used to avoid communication interference when
using long cables.
Use shielded 7 conductor cable of 0.14 mm
2
section.
Transmission speed.
The CNC can operate at up to 115,200 Baud.
It is recommended to ground the unused pins in order to avoid erroneous control and data signal
interpretations.
Ground connection.
It is suggested to reference all control and data signals to the same ground cable (-GND- pin) thus,
avoiding reference points at different voltages especially in long cables.
