COMMUNICATION PARAMETERS
Communication Parameters control the transmission
of data to and from the WS Controller via an RS-485
serial interface. These settings allow the controller to
be configured to communicate with a device having
RS-485 capabilities. The RS-485 configurable
parameters are listed below. See Figure 4-16.
Modbus Address—Click in “Modbus address” to
enter a modbus address for the compressor modbus
communications on the RS485 port. The address
may be between 1 and 247. This change takes affect
after the controller power is cycled off and on.
Baud Rate—The rate of data transmission in bits per
second. The overall range is 1200 to 57,600 baud.
The default baud rate is 19200 bps.
Parity—Data checking method for verifying accuracy
of data transmission. Parity options for data checking
are odd, even, none. The default setting is “Even.”
INTERNET TRANSMISSION SETTINGS
Some controllers may be configured to allow access
and transmission of data via the internet. These
settings have no effect on standard controllers. The
TCP/IP parameters are:
IP Address—The unique address the WSPC will use
to identify and communicate with another computer
via the internet or other network utilizing the Internet
Protocol standard.
Net Mask—used to determine what subnet an IP
address belongs to.
Name Server—computer server that implements a
name service protocol used to correlate the server
name with the IP address.
Gateway—The access address allowing data to
pass to and from the network.

NOTE
The Modbus settings assigned here must
match the modbus settings assigned in
the WSPC User Profile or other Modbus
applications. If the settings do not match,
communication with the controller will be
lost when the controller is cycled.
