Data Baud Rate
—Data rate (payload) for the
COM
port in
bits-per-second. [
1,200–115,200; 19200
]
•
Configuration
—Interface signaling parameters. Data bits, par-
ity 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; Disabled
]
•
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, Custom; Seamless
]
•
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.
[
