How to use the EZB Connections robot skill

Main Window

The main window lists each extra connection you add. Each row represents one additional EZ-B that ARC can connect to. You will choose how to reach that EZ-B (for example: a COM port or an IP address), then press Connect.

Screen Guide (numbers match the image)
1. Add Button

Adds a new connection row to the list. Each time you click Add, ARC creates the next available connection number. You can add connections up to index #255.

Tip: These extra connections start at #5 because the standard ARC connection control covers connections #0–#4.
2. Delete Button

Removes connection rows starting from the highest connection number (the last one in the list). Use this if you added too many connections or want to simplify your project.

Tip: If you want to remove a specific connection in the middle, you may need to delete down to it and re-add what you need.
3. Connection Number

Shows the assigned connection number for that row (from 5 up to 255). This number matters because ARC uses connection numbers to know which EZ-B a control or script command should talk to.

Example: You might connect a “head” EZ-B on connection #0 and an “arm” EZ-B on connection #5.
4. Connect Button

Connects ARC to the EZ-B for that row. Before clicking it, select the correct COM port or IP address in the drop-down (item #5).

Tip: If it fails to connect, double-check you selected the right port/address and that the EZ-B is powered on and reachable.
5. Device Address or Port Drop-down

This is where you choose how ARC will reach your EZ-B:

  • COM Port (common for USB/serial devices): pick the COM port that your EZ-B is using.
  • IP Address (common for WiFi/Ethernet devices): pick or enter the IP address of the EZ-B on your network.
Tip: If you don’t see the device you expect, refresh the list (if available) or confirm your PC can see the device/network.
Beginner Workflow (Quick Steps)
  1. Connect and power your additional EZ-B(s).
  2. In ARC, open the EZB Connections skill.
  3. Click Add until you have one row for each additional EZ-B you want to use.
  4. For each row, choose the correct COM port or IP address from the drop-down.
  5. Click Connect on that row and verify it connects.
  6. Repeat for each additional EZ-B.

Videos

These videos demonstrate how to set up and use multiple EZ-B connections in ARC. Watch them while following along in your own project.

Requirements

  • One or more EZ-B I/O controllers.
  • A PC running Synthiam ARC.
  • The correct connection method for each EZ-B (for example: USB/serial COM port or network IP address).

I've added this skill but it doesn't seem to have a scan for auto discovery, kind of need this when you are using the EZ-Bs in client wifi mode.
