•
Mode
—Set the method the host uses to connect to the radio.
[
Serial, Network; Network
]
•
Remote UnitID
—Specify the Remote(s) to which
transmissions are directed. Enter “broadcast” to send
transmissions to all Remotes, or enter the Unit ID number of
a particular Remote for unicast (directed) data. The Unit ID
defaults to the last four digits of the radio serial number, but
can be set to any 32-bit integer.
[
Remote ID, Broadcast; Broadcast
]
•
Remote COM Port
—Choose which serial port on the Remote
radios through which all data are sent (
COM1
or
COM2
).
[
COM1, COM2; COM2
]
•
Baud Rate
—Set the data rate (payload) for the
COM
port in
bits per second . [
1200–115200; 19200
]
•
Byte Format
—Set the interface signaling parameters: baud
rate (see
Baud Rate
above for allowable range), data bits,
parity, and stop bits. [
7N1, 7E1, 7O1, 8N1, 8E1, 8O1; 8N1
]
•
Buffer Size
—Select the appropriate value for the buffer size
for each serial message. The maximum AP buffer size for
incoming serial data is 256 bytes. Incoming serial packets
(from the RTU) larger than 256 bytes are split by the AP into
256-byte packets before being transmitted over the air. The
associated remote(s), on receiving these packets, transmit
them out the serial port as separate packets. This parameter
does not affect serial data/packets received by the AP (from
remotes) over the air and transmitted out of the local AP
serial port. [
32, 64, 128, 256 bytes; 64
]
•
Inter-Packet Delay
—Set the number of characters that signify
the end of a message (inter-character time-out). A transceiver
receiving data through the serial port sends an
end-of-message signal to the remote end. MODBUS
®
defines a “3.5-character” parameter. [
0–65535; 4
]
•
Commit Changes and Exit Wizard
—Implements the settings
shown on the screen and closes the Serial Configuration
Wizard.
