Notes:
1. The following connections comply with IEC 61000-4-5 Installation Class 4 surge immunity levels: COM 1–6, I/O 1–

2. A BACnet and IP license is required. A free license is available to support up to 50 BACnet objects on a single
4-Series control system. Support for more than 50 BACnet objects requires the purchase of one
SW-3SERIES-BACNET-50+ license. The PRO4 supports a maximum of 2000 BACnet objects when dedicated for
BACnet use only. Actual capabilities are contingent upon the overall program size and complexity. To obtain the
license, visit www.crestron.com/bacnetlicense.
