1 The letter G in a model's product code indicates that the model is the Buy American version.
2 These models are intended for use with the ADS-Lite-A servers (only) in Australia, China, Hong Kong, India, Indonesia, Japan, Korea, Malaysia, New Zealand, Philippines, Singapore, Taiwan, Thailand, Vietnam, and select branches within regions of Africa and the Middle East.
3 Only the supported USB integration adapters function with the SNE. Other integration adapters that are not supported cannot function with the SNE.
4 Two Ethernet device connections include one integral Ethernet port and the USB-to-Ethernet adapter, ACC-USBETH-0, as the second Ethernet port. BACnet/SC is not supported at this time. The second BACnet/IP trunk is supported only at Release 13.0 and later.
5 Direct Ethernet connection only. USB-to-Ethernet adapter does not support BACnet/SC at this time.
6 Multiple IP integrations can be on an engine, including BACnet/IP and BACnet/SC, but this is limited by the maximum devices that you can map to a trunk. The total number of BACnet/IP or BACnet/SC devices that you can map is 150. You cannot map 150 IP and 150 SC devices at the same time because they use the same BACnet Integration object.
7 Suggested object limit for performance considerations.
