![]() Interfacing between the DA device and the NIC is via the serial UART. Please refer to the individual product specification documents for further details on the DA NIC. The DA NIC features a single TTL-level serial Universal Asynchronous Receiver/Transmitter (UART) for interfacing with the DA device (e.g. The Communications Module or Network Interface Card (NIC), is available in a number of form factors. The DA NIC is based on the NIC511 Communications Module, which has a rectangular form factor and is shown below in Figure 2. This is often used for DA only customers. Please consult with Itron personnel to discuss further. Other network architectures are possible. As an example it is possible to have so called “In-band-monitoring” where the Device management traffic flows through the Master Bridge. This software includes UIQ (primarily for metering) and GridScape (primarily for DA devices). This traffic typically follows a different path and exits the mesh at an Access Point and uses a different backhaul network to get back to the back office software. This includes collection of statistics, managing configuration, firmware, etc. SCADA traffic is then transported across the utility’s backhaul network to the SCADA/DMS/EMS system. The Bridges and DA NIC can be configured with either IPv4 or IPv6 addresses.ĭevice management traffic is shown in dark green. The Master Bridge provides the gateway between the RF mesh and the backhaul network, and is typically installed at a substation with IP backhaul. NIC integrated DA device) via other Remote Bridges and Relays to a Master Bridge. DA/SCADA traffic flows are shown in dark blue, going from the endpoint (e.g. The typical DA network architecture is shown in Figure 1. ![]()
