Scenarios

Serial, Network and Cloud Console Scenarios

Choose the workflow that matches your task, then verify it with observable connection, traffic and command results.

Scenarios

Choosing a remote access path

RFC 2217, transparent TCP or Cloud Console -- what each requires and what each can do.

Read guide

Networking and remote access

Reach a serial port across the network, or put its data onto one.

Debug a serial port from anywhere on the Web

Use Cloud Console across locations and NAT without routing directly to the site or opening an inbound TCP port.

  1. On-site SPU
  2. Cloud Console
  3. Browser anywhere
Open scenario

Connect directly with RFC 2217

Reach a serial server directly over a LAN or VPN and control its serial parameters as well as its data.

  1. RFC 2217 Client
  2. Reachable LAN or VPN
  3. On-site serial server
Open scenario

Connect an isolated site outward

Use an outbound TCP client when the device site cannot accept inbound connections.

  1. Serial device
  2. SPU TCP Client
  3. Central server
Open scenario

Forward serial telemetry over UDP

Turn NMEA or sensor messages into correctly framed UDP datagrams for a LAN collector.

  1. Sensor
  2. SPU framing
  3. UDP collector
Open scenario

On-site diagnosis and maintenance

Watch a live link, keep evidence from an overnight run, or reflash the device.

Monitor a serial conversation inline

Capture both directions between an existing host and device without changing the protocol.

  1. Existing host
  2. SPU bridge
  3. Serial device
Open scenario

Poll a Modbus RTU device reliably

Build a repeatable request, verify CRC and separate timeout from framing failures.

  1. SPU poll command
  2. RS-485 adapter
  3. Modbus device
Open scenario

Capture an intermittent fault overnight

Record timestamped traffic with bounded files and preserve a useful incident window.

  1. Serial link
  2. SPU logging
  3. Rotated evidence files
Open scenario

Update device firmware over serial

Send an image to a bootloader with YMODEM, locally or through a device server.

  1. Firmware image
  2. SPU YMODEM
  3. Device bootloader
Open scenario
