Ethernet port
The 415U modules provide a standard RJ-45 Ethernet port compliant
to IEEE 802.3 10/100Base-T. This port provides full access to the
module, including configuration, diagnostics, log file download, and
firmware upload of both the local and remote units. Additionally, the
Ethernet port can provide network connectivity for locally connected
third-party devices with Ethernet functionality.
USB device port for configuration
The 415U modules also provide a USB device (USB-B) connector.
This connector provides configuration of the device and remote
configuration access to other devices in the radio network.
RS-232 port
The 415U modules provide an RS-232 serial port that supports
operation at data rates up to 230,400 baud. This port supports
Modbus protocol. The RS-232 port is accessed using an RJ-45
connector wired as a DCE according to the EIA-562 Electrical
Standard.

RS-485 port with Modbus support
The 415U modules provide an RS-485 serial port that supports
operations at data rates up to 230,400 baud. The default baud rate is
9600 baud, no parity, 8 data bits and 1 stop bit, which matches the
115S serial expansion module default settings. This port supports the
Modbus protocol.
The RS-485 port terminal is hosted on the four-way expansion
connector on the bottom edge of the module. An on-board RS-485
termination resistor provides line termination for long runs. As a
general rule, termination resistors should be enabled at each end
of the RS-485 cable. When using 115S expansion I/O modules,
remember to enable the RS-485 termination resistor switch that is
located on the end module.
