8.2.5 BACnet MS/TP, BACnet Ethernet and BACnet Explorer
• Max Info Frames – the number of transactions the Router may initiate
while it has the MS/TP token. Default is 50.
• Max Master – the highest MAC address to scan for other MS/TP
master devices. The default of 127 is guaranteed to discover all other
MS/TP master devices on the network.
• MAC Address – legal values are 0 to 127, must be unique on the
physical network.
• Baud Rate – the serial baud rate used on the network.
• Token Usage Timeout (ms) – the number of milliseconds the router
will wait before deciding that another master has dropped the MS/TP
token. This value must be between 20ms and 100ms. Choose a larger
value to improve reliability when working with slow MS/TP devices that
may not be able to meet strict timing specifications.
