Page 5: Introduction
Introduction The SeaConnect 370 has a small form-factor I/O board featuring a TI CC3200 Cortex ARM-M4 MCU with integrated Wi-Fi capability. The SeaConnect 370 can also be configured with a cellular modem. It includes 2 Form C relays, 4 discrete inputs, and 2 12-bit A/D converters, each configurable independently for either 0–10 VDC voltage measurement or 0–24 mA current measurement mode.

Page 14 The 1-Wire bus system uses a single primary controller to control one or more secondary devices. The SeaConnect 370 is the primary controller for up to 10 secondary devices. When there is only one secondary device on the bus, the system is referred to as a “single-drop” system; the system is called “multidrop” if there are multiple secondary devices on the bus.
