MS/TP network settings are items E, F, and G on the

Change Configuration menu.
See the BACtalk System Design Guide (LTBT-TM-SYSDSGN) for more
information about MS/TP configurations.
Use MS/TP to connect up to 10 BACnet MS/TP devices to the VLX. See Figure
6 on page 11 for more information. Do not connect the VLX to the BACnet
internetwork using MS/TP unless data traffic requirements are relatively low and
Ethernet connection is cost-prohibitive or otherwise difficult to provide. Ethernet
is the preferred primary connection method.
When connecting a VLX using MS/TP (primary connection), the total number of
devices on that MS/TP should be limited to 10 or fewer. Other factors also affect
network performance such as global-controller-hosted VLC point alarms, global
controller DDC references to devices on the MS/TP, and active operator
workstations requesting data from devices on the MS/TP.
