Communication
1. Dedicated Inputs/Outputs
Connection to DB37F connector
This connector is used to communicate with the machine. It
groups dedicated inputs and outputs that are used in the
marking cycle.
The pins are numbered from 1 to 37.
Connections and cabling: separate the power supply cables from the control cables in
cable ducts and in the cabinet (for control cables, a section of 0.34 mm
2
is recommended).
Equipment filtering: the relays connected to the marking machine should include a device
for suppressing interference on the operating coil (freewheeling diode for DC relays or RC
circuit for AC relays).
Connection of shielding: the communication cables (All Or Nothing I/O or RS232
computer cables) must be shielded with both ends of the shielding connected to the
equipment earth via the shortest possible link.
Grounding: connect together all the conductive metal grounds (no paint or treatment such
as anodization) of the equipment (frame, cabinet, marking machine) to ensure effective
connection. Where possible, there should be multiple connection points to improve the
connection quality.
