some are reserved for special applications in data networks.

valid IP address may be entered here.

Modbus TCP<->RTU Conversion
RTU, and conversely, Modbus RTU to Modbus TCP. This feature eliminates the need for
external equipment to handle the conversion. Only available when in TCP Server Mode.
The Terminal Server supports the following communication protocols:
• Point-to-Point: TCP or UDP
• Point-to-Multipoint

• Multipoint-to-Multipoint

Data from local multicast IP addresses is always delivered to the socket layer by the radio's TCP/IP stack.
Therefore, to receive data from local multicast IP addresses, simply set the Local Radio IP Port equal to the des-
tination IP port of the multicast IP packet.
Using the Terminal Server — Typical Example
The following describes a Terminal Server implementation in a radio network. Figure 33 below
