A terminal server will not translate HMI/PLC polling message protocols that are not designed
to be wrapped in an IP package. Most SCADA protocols are not designed to be used with a
terminal server. As an example, the Modbus RTU message is a serial protocol. The Modbus
TCP/IP protocol is an Ethernet IP protocol. The Modbus RTU message cannot be wrapped in
an IP package to form a Modbus TCP/IP polling message. A protocol translation must take
place. A device can be purchased that will perform the translation. Please contact your local
SCADA dealer or CalAmp Tech Support to determine if your SCADA protocol can be used
with a terminal server.
