BACnet - Visual Test Shell – How to test an MSTP Device

In order to test a BACnet MSTP device using the Visual Test Shell (VTS) there are a few items to take into consideration:

1)           The VTS will not connect to an MSTP link using an RS-485 port on a PC.

2)           The most common way to connect VTS with MSTP is to connect the VTS on IP and use a BACnet IP-to-MSTP router.

3)           The MSTP tab in the VTS Ports dialogue uses a device called the NB-Link from American Auto-Matrix.

If you do not have a NB-Link from American Auto-Matrix you must use the IP-to-MSTP router option to test the MSTP device with VTS.
