Cables
The following instructions refer to the figures in
• The general cable type specifications are: CAT5 twisted pair + additional CAT5 twisted pair, shielded cable AWG 24
(or AWG 22) stranded flexible
It is recommend to use 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 (that is, 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

Response Time
The following figure shows the response time of the ID-NET network. This time is defined as the period between the Trigger
activation and the beginning of data transmission to the Host.
