The Table 12 on Page 102 above shows the real time
error numbers that may be encountered during commu-
nication setup, along with a description of each.
This data can be read and in some cases modified
using a BACnet, Modbus, or N2 network connection.
The BACnet Name is a 12 character or shorter name
used to identify the data in BACnet. The AI, AV, BI,
and BV columns are indexes used to select the data.
The AI, AV, BI, and BV number associated with a
BACnet Name should not be changed. If a value is
not wanted in this table, change the BACnet Name to
SPARE_XX_##. SPARE rows can be used for new
values.When set to BACnet or N2, communications
automatically sets Stop Bit (1) and Parity (None) for
port.
When connected via BAS and port is set for BACnet,
Modbus, or N2, the remote settings will continue to
follow the remote setpoints until the port is changed
to another protocol or DEmodifier address is set to -1.
The table below shows set-up requirements for each
communication protocol.
