Note for B5C:
The B5C supports BACnet MS/TP protocol and can be networked to form a BACnet
MS/TP network.
The B5C default baud rate is 38400bps.
Each B5C on the MS/TP network must have a unique BACnet MAC address and unique
Device Instance Number (Object ID).
B5C valid MAC addresses are 0-127 for master node, 0-254 for slave node.
B5C default MAC address is 126.
Default Device Instance Number (Object ID) is 4005.
The B5C power supply and RS-485 connection are similar to the Q5C. The B5C doesn't
have terminal blocks TB4 and TB6.
Avoid running communication wires or sensor input wires next to AC power wires or the
relay output wires. These can be sources of noise that can affect signal quality.
The B5C has a half wave rectifier on board. You will damage devices if you mix half
wave and full wave rectifiers on the same AC source. Use extreme caution when
sharing a common AC source. Sharing a common DC source is less problematic.
When the B5C input power is AC, the 24VAC can be either grounded or non-grounded.
Polarization is very important when the B5C is connected to a network. Make sure the
Neutral is connected to the GND of TB5.
