Serial Mode
—When seamless mode is selected, data bytes will be sent over the air as quickly as pos-
sible, but the receiver will buffer the data until enough bytes have arrived to cover worst case gaps
in transmission. The delay introduced by data buffering may range from 22 to 44 ms, but the radio
will not create any gaps in the output data stream. This mode of operation is required for protocols
such as MODBUS™ that do not allow gaps in their data transmission. [
Seamless, Custom; Seamless
]
•
Seamless Inter-Frame Delay
— Number of characters that represent the end of a message (inter-char-
acter time-out). MODBUS defines a “3.5-character” parameter. [
1–65,535; 4
]
NOTE:
With MODBUS/RTU mode, poll requests may be fragmented when using COM port baud rates
above 19200 bps via a USB/Serial adapter (FTDI). This may cause incorrect checksum/CRC
errors and thus, timeouts.
•
Custom Data Buffer Size
(Custom Packet Mode only)—Maximum amount of characters, that the
Remote end will buffer locally before starting to transmit data through the serial port. [
16, 32, 64, 128,
256; 32
]

Commit Changes and Exit Wizard
—Save and execute changes made on this screen (Shown only after
changes have been entered.)
A PPP session shows the following possible states:
•
Sending LCP Requests
—The PPP server is querying for any clients that need to connect.
•
Link Established
—A successful PPP connection has been negotiated and an IP address is assigned.
•
Port not Enabled
—The serial port is disabled.

•
Status
—Enable/Disable the serial data port.
•
IP Protocol
—DF1/EIP Protocol. This is the type of IP port that will be offered by the transceiver’s
serial device server.
[TCP, UDP, PPP, DF1/EIP, MODBUS/TCP Server; TCP]
•
Data Baud Rate
—The baud rate of the transceiver’s serial port to which the external device is con-
nected.
[1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, Autobaud; Autobaud]
•
Security Descriptor Mask 1/2
—Use to control which IP addresses can access the serial device con-
nected to the iNET radio.
[Valid IP Address; 0.0.0.0]
•
Email Server IP Address
—IP Address of the (optional) email server.
[Valid IP Address; 0.0.0.0]
•
Email From String
—Text to identify the sender.
[Valid email address; blank]
•
IP Routing Information
—The desired IP addresses for message routing.
•
Email Routing Information
—The desired email destination address(es) for message routing.
