6.1.5
BACnet IP Secondary
Enable BBMD - select this checkbox to enable the Router to
act as a BBMD.
Public IP Address and Port - if the BBMD is being accessed
across a NAT Router, then these values must be configured with the
public IP address and Port by which the BBMD can be reached from
across the NAT Router. The Public IP Address and Port would also be
used in the BDT of remote BBMD's that need to reach this BBMD
across the NAT Router. If no NAT Router is being used, these fields
can be left blank.
IP Port - this MUST be different to the IP Port used on the BACnet IP Primary connection. Default is 47809
(0xBAC1).
6.1.6
BACnet MSTP
Max_Info_Frames - the number of transactions the Router may
initiate while it has the MSTP token. Default is 50.
Max_Master - the highest MAC address to scan for other MSTP
master devices. The default of 127 is guaranteed to discover all other
MSTP master devices on the network.
MAC Address - legal values are 0..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
MSTP token. This value must be between 20ms and 100ms. Choose a
larger value to improve reliability when working with slow MSTP
devices that may not be able to meet strict timing specifications.
