4.3.1 ID-NET Cables

The following instructions are referred to Figure 40, Figure 41 and Figure 42.
 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 (ID+ and ID-).
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).

Reader's chassis may be connected to earth.
 Network inside the same building.

* Application dependent, contact your Datalogic Automation representative for details.
NOTE: The default ID-NET baudrate is 500 kbps. Lower ID-NET baudrates
allow longer cable lengths.
