5.3.1 ID-NET™ Cables

The following instructions are referred to Figure 70, Figure 71 and Figure 72.

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.

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.
