Analog Devices Inc. DC2321A

Overview

DC2321A from Analog Devices is a SmartMesh IP Evaluation Kit interface board designed to enable USB-based serial communication between host PCs and SmartMesh IP Manager or Mote devices. It provides FTDI-based USB-to-serial bridging, supports dual CLI/API port access at 9600/115200 baud, and is required for connecting DC9001A/B, DC9020A, or DC9003A-B modules to development hosts. It is used in wireless sensor network evaluation, industrial IoT prototyping, and low-power mesh network validation.

For engineers reviewing the DC2321A datasheet, DC2321A pinout, DC2321A application, or DC2321A equivalent, this page delivers verified hardware interface specifications, confirmed USB-to-serial configuration, exact COM port mapping for CLI/API access, and validated integration requirements with SmartMesh IP Managers (e.g., DC9001, DC2274A-A) and motes (e.g., DC9003A-B, DC9018A-B).

Technical Context

The DC2321A implements an FTDI FT232RL-based USB-to-serial bridge with configurable UART interface logic, supporting simultaneous CLI (9600 baud) and API (115200 baud) channel access to SmartMesh IP devices. It includes on-board power regulation, LED status indicators (STATUS_0, INDICATOR_0), and jumper-controlled LED_EN for debug visibility.

It interfaces exclusively with SmartMesh IP SoC-based hardware - specifically LTC5800-IPM/LTC5800-IPR derivatives - and requires precise COM port enumeration order (3rd = CLI, 4th = API) for compatibility with Serial Mux, Stargazer GUI, and SmartMesh SDK tools. No onboard firmware or programmable logic is present.

FAQ

What is the DC2321A used for in a SmartMesh IP development workflow?

The DC2321A serves as the mandatory USB interface board for connecting host PCs to SmartMesh IP Managers (e.g., DC9001A) and Motes (e.g., DC9003A-B). It enables both CLI debugging at 9600 baud and API-driven automation at 115200 baud - essential for running Stargazer GUI, Serial Mux, and SmartMesh SDK tools. Without DC2321A, direct USB communication with most SmartMesh IP evaluation hardware is not supported.

Does the DC2321A require drivers, and which operating systems are supported?

Yes, the DC2321A requires FTDI Virtual COM Port (VCP) drivers. It is natively supported on Windows (XP through 10), Linux (kernel ≥2.6 with ftdi_sio module), and macOS (10.9+ with FTDI VCP drivers). Driver installation creates four enumerated COM ports per connected device, with the third and fourth assigned to CLI and API respectively - a requirement confirmed in the SmartMesh IP Tools Guide.

How does the DC2321A differ from the DC9006 interface board?

The DC2321A is functionally identical to the DC9006 - both are FTDI-based USB-to-serial interface boards for SmartMesh IP hardware. The DC2321A supersedes DC9006 in newer kit configurations (e.g., DC9021B) and shares the same pinout, jumper layout (including LED_EN), and COM port behavior. Documentation confirms they are interchangeable for all supported Manager/Mote combinations.

Can the DC2321A be used with DC2274A-A or DC2274A-B devices?

No - the DC2274A-A (Manager) and DC2274A-B (APM) connect directly via USB without requiring the DC2321A. These modules integrate native USB functionality and enumerate their own COM ports. The DC2321A is only required for legacy or non-USB-enabled SmartMesh IP hardware such as DC9001A/B managers and DC9003A-B motes.

What is the role of the LED_EN jumper on the DC2321A?

The LED_EN jumper on the DC2321A enables or disables the STATUS_0 and INDICATOR_0 LEDs on connected SmartMesh IP devices. When shorted, it allows real-time visual feedback during network join, message transmission, and fault conditions - critical for initial bring-up. For accurate power measurement or long-term operation, the jumper must be removed to eliminate >100× current draw from LEDs.
