30 MDS TransNET Ref. Manual MDS 05-2708A01, Rev. E
The first parameter (xxxxx) is baud rate. Baud rate is specified in
bits-per-second and must be one of the following speeds: 300, 600, 1200,
1800, 2400, 4800, 9600, 19200, 38400, 57600, or 115200. At baud rates of
19200 bps or less, the radio can support unlimited continuous data transmis-
sion at any hop rate.
The second parameter of the
BAUD command (abc) is a 3-character block
indicating how the data is encoded. The following is a breakdown of each
character’s meaning:
a = Data bits (
7 or 8)
b = Parity (N for None, O for Odd, E for Even)
c = Stop bits (
1 or 2)
The factory default setting is 9600 baud, 8 data bits, no parity, 1 stop bit
(Example:
9600 8N1).
NOTE: 7N1, 8O2, and 8E2 are invalid communication settings and are not supported
by the transceiver.
BAND [A, B, C]
Select Sub-Band (Normally used for 2.4 GHz model)
This command sets or displays the receiving and transmit operating band for
the radio.
A = 2.4016–2.4270 GHz
B = 2.4272–2.4526 GHz
C = 2.4528–2.478.2 GHz
NOTE: The same
BAND must be programmed at the time of installation and
must be common across each radio in a given network.
BUFF [ON, OFF]
Data Buffer Mode
This command sets or displays the received data handling mode of the radio.
The command parameter is either
ON or OFF. (The default is OFF.) The
setting of this parameter affects the timing of received data sent out the
DATA
connector. Data transmitted over the air is unaffected by the BUFF setting.
If data buffering is set to
OFF, the radio will operate with the lowest possible
average latency. Data bytes are sent out the DATA port as soon as an incoming
RF data frame is processed. Average and typical latency will both be below
10 ms, but idle character gaps may be introduced into the outgoing data flow.
If data buffering is
ON, the radio will operate in a seamless mode. That is, data
bytes will be sent over the air as quickly as possible, but the receiver will
buffer the data until the entire packet has been collected. The delay introduced
by data buffering is variable and depends on message size and the number of
retransmissions required, 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.
