• Serial Mode— If data buffering is Enabled, the radio will oper-
ate in seamless mode. 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 trans-
mission. 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™ and some variants which do
not allow gaps in their data transmission.

• Seamless Inter-Frame Delay— Number of characters that repre-
sent the end of a message (inter-character time-out). MOD-
BUS defines a “3.5-character” parameter.

1–65,535; 4]
• Custom Data Buffer Size (Custom Packet Mode only)—Maxi-
mum amount of characters, that the Remote end will buffer
locally before starting to transmit data through the serial port.

• Status—Enable/Disable the serial data port.
• IP Protocol—TCP Server. This is the type of IP port that will
be offered by the transceiver’s serial device server.

TCP, UDP, PPP; TCP]
• Local Listening IP Port—Receive IP data from this source and
pass it through to the connected serial device. The port num-
ber must be used by the application connecting to local TCP
or UDP socket.
