5.3.1 ID-NET™ Cables
The following instructions are referred to Figure 57, Figure 58 and Figure 59.
 The general cable type specifications are: CAT5 twisted pair + additional CAT5 twisted
pair, shielded cable AWG 24 (or AWG 22) stranded flexible.
We recommend using
DeviceNet cables (drop or trunk type) to the following reference
standards:
AN50325 – IEC 62026
UL STYLE 2502 80°C 30V
 Cable Shield MUST be connected to earth ground ONLY at the Master.
 NEVER use ID-NET™ cable shield as common reference.
 The ID-NET™ max cable length depends on the baudrate used, (see the Baudrate Table
below).
 For Common Power Connections use only 2 wires (23 and 24).
- DC Voltage Power cable (Vdc – GND) should be handled as a signal cable (i.e. do not
put it together with AC cable):
- Wire dimensioning must be checked in order to avoid voltage drops greater than 0.8
Volts.
- Cable should lie down as near as possible to the ID-NET™ cable (avoiding wide loops
between them).
 Scanner's chassis may be connected to earth.
 Network inside the same building.

NOTE
The default ID-NET™ baudrate is 500 kbps. Lower ID-NET™ baudrates
allow longer cable lengths. The baudrate is software configurable by
authorized Datalogic Automation personnel only.
