Visual Test Shell – Testing 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.
