AUTO SERIAL CONFIGURATION
Auto serial configuration enables the device to determine the baud rate, parity and
stop bits directly from the serial traffic. This allows a device to be quickly and easily
deployed after a valid RS-485 MAC address is chosen. Note that the auto configuration
procedure assumes a serial configuration appropriate to the selected protocol as
follows:
When Modbus
®
communications protocol is selected, and the device is setup offline or
away from the main network, it is necessary to generate traffic in order to configure the
serial communication. Attempting to read input registers is a good method to generate
traffic. Note that while serial configuration is in progress, the device may not respond
to requests. The device may require multiple read requests to complete the serial
configuration process.
The auto serial configuration process will complete once a message addressed to the
device is received and processed successfully. The serial configuration parameters
are then saved to non-volatile storage and loaded by default each time the device
starts. If the serial configuration of the bus changes, a power cycle of the device is
required to restart the auto serial configuration process.
BACnet Communication Protocol Services
Device Communication Control Service (DM-DCC-B)
This device supports the Device Communication Control Service BIBB. The optional
time duration in minutes is also supported. This device is configured with a password
that must be provided to successfully execute this command.
The password is
“Dwyer”.
Reinitialize Device Service (DM-RD-B)
This device supports the Reinitialize Device Service BIBB. The supported device
states are COLDSTART and WARMSTART. All other states return error. This device
is configured with a password that must be provided to successfully execute this
command.
The password is “Dwyer”.

Note:
The default object identifier is 607xxx, where xxx is replaced by the MS/TP
MAC address set in the ADDR SUB MENU under the Conn MENU. The object
identifier value will change as the MS/TP MAC address changes. However, if a
specific object identifier is written via BACnet communication protocol, then that
value is stored and changes to the MS/TP MAC address will no longer affect the
object identifier. Similarly, the default object name includes 607xxx. The object name
will reflect the current object identifier. If a specific object name is written via BACnet
communication protocol, then that value is stored and changes to the object identifier
will no longer affect the object name.
