Industrial Electronic Devices

ETHERNET:

The BACnet/IP connection must be made using Connector3 and/or Connector4 of HD67716-IP-A1 with at least a Category 5E cable. The
maximum length of the cable should not exceed 100m. The cable has to conform to the T568 norms relative to connections in cat.5 up to
100 Mbps. To connect the device to an Hub/Switch is recommended the use of a straight cable, to connect the device to a PC/PLC/other is
recommended the use of a cross cable.
RS485:
The BACnet MS/TP connection must be made using Connector5 of HD67716-MSTP-A1.
To terminate the RS485 line with a 120Ω resistor it is necessary to put ON dip 1, like in figure.
The maximum length of the cable should be 1200m (4000 feet).
Here some codes of cables:
Belden: p/n 8132 - 2x 28AWG stranded twisted pairs conductor + foil shield + braid shield;
Belden p/n 82842 - 2x 24AWG stranded twisted pairs conductor + foil shield + braid shield;
Tasker: p/n C521 - 1x 24AWG twisted pair conductor + foil shield + braid shield;
Tasker: p/n C522 - 2x 24AWG twisted pairs conductor + foil shield + braid shield.
