| Phase | |||
| Your choices are... | |||
| Single Phase | Standard commercial and residential power is single-phase, meaning one sinusoidal or other alternating voltage pattern. | ||

| BCD | Binary coded decimal (BCD) is a circuit code which represents decimal numbers in binary code. With BCD, each decimal digit is represented by the four-bit binary representation of the digit. | ||
| D/A | The output interface is digital-to-analog (D/A). | ||
| Ethernet | Ethernet is a local area network (LAN) protocol that uses a bus or star typology and supports data transfer rates of 10 Mbps. The Ethernet specification is the basis for the IEEE 802.3 standard, which specifies the physical and lower software layers. To handle simultaneous demands, Ethernet uses carrier sense multiple access / collision detection (CSMA/CD) to monitor network traffic. | ||
| Wireless | The device has a wireless connection as its interface. | ||
