4.3.1 ID-NET™ Cables
The following instructions are referred to Figure 36, Figure 37 and Figure 38.

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.
Baudrate Table
Baud Rate 125 kbps 250 kbps 500 kbps 1Mbps
Cable Length 1200 m 900 m 700 m *
* 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. The baudrate is software configurable by
authorized Datalogic Automation personnel only.
