Rotary Switch Settings; To Set Up Autobaud - Carrier TruVu ChillerVu Installation And Startup Manual

Rotary switch settings

Rotary switch settings (see example below) are used to determine the following items in your system, so you
should plan carefully before setting the switches.
•
If you use a Default IP address, the final octet is the number created by the three rotary switch settings (must
be a unique number from 1 to 253). See To set the IP address (page 18).
•
If you autogenerate the following:
Device Instance, the number is automatically set to a number equal to the ((IP network number x 100) +
rotary switch settings).
BACnet Network Number for Port S1, the number is automatically set to a number equal to the ((IP network
number + rotary switch settings) x 10).
Autogenerating is set up through the controller setup pages (page 42).
•
The rotary switch settings determine the router number in the i-Vu® interface.
EXAMPLE The switches below are set to 125.
CAUTION Do not leave the rotary switches set at 0 (the factory default). The TV-PSM cannot be discovered if
the rotary switches are left at 0.

To set up autobaud

The TV-PSM can automatically receive or establish the baud rate on a serial network. When you configure a device
on the network for autobaud and then power it up, the device detects the incoming baud rate on the network and
sets its baud to match.
Autobaud does not work unless there is a device on the network, whether Carrier or third party, that has the baud
rate already set. You can manually set the baud rate on more than one device, as long as the rate is the same for
every device.
NOTES
•
The received baud rate stays intact during power cycles.
•
We recommend you set the baud rate manually on the router for the network.
