•
IP Protocol
—Point to Multipoint [
TCP, UDP PPP; TCP
]. This is
the type of IP port that will be offered by the transceiver’s
serial device server.
•
Multicast IP Address
(used instead of
Local IP Address
when
using UDP Point-to-Multipoint.)— Must be configured with
a valid Class D IP address (224.0.0.0–239.255.255.255). IP
packets received with a matching destination address will be
processed by this unit [
Any legal IP address; 0.0.0.0
].
•
Multicast IP Port
(used instead of
Local IP Port
when using UDP
Point-to-Multipoint.)—This port number must match the
number used by the application connecting to local TCP or
UDP socket. [
1-64,000; COM1: 30010, COM2: 30011
]
•
Local IP Port
—Receive IP data from this source and pass it
through to the connected serial device. The port number must
be used by the application connecting to local TCP or UDP
socket. [
Any valid IP port; COM1: 30010, COM2: 30011
]
•
Time to Live (TTL)
—An IP parameter defining the number of
hops that the packet is allowed to traverse. Every router in the
path will decrement this counter by one.
•
Packet Redundancy Mode
— For proper operation, all radios’
Serial Packet Redundancy mode must match (Single Packet
mode vs. Packet Repeat mode). This is because a transceiver,
when in Packet Repeat mode, sends 12 extra characters
(sequence numbers, etc.) to control the delivery of the
repeated data. Misconfigurations can result in undesired
operation.
•
Data Baud Rate
—Data rate (payload) for the
COM
port in
bits-per-second. [
1,200–115,200; 19200
]
•
Configuration
—Formatting of data bytes. Data bits, parity and
stop bits [
7N1, 7E1, 7O1, 8N1, 8E1, 8O1, 8N1, 7N2, 7E2, 7O2, 8N2,
8E2, 8O2; 8N1
].
•
Flow Control [Com2 Only]
—RTS/CTS handshaking between
the transceiver and the connected device. [
Enable, Disable; Dis-
abled
]
•
Serial Mode
—When seamless mode is selected data bytes will
be sent over the air as quickly as possible, 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 permits
operation with protocols such as MODBUS™ that do not
allow gaps in their data transmission. [
Seamless, Custom;
Seamless
]
•
Seamless Inter-Frame Delay
— Number of characters that repre-
sent the end of a message (inter-character time-out). UDP
packet sizes are delimited and sent out based on the Seamless
Inter-Frame Delay only when receiving data through the
serial port. MODBUS defines a “3.5-character” parameter.

1–65,535; 4
