BUFF [ON, OFF]

This command sets or displays the received data handling mode of the
radio. The command parameter is either
The setting of this parameter affects the timing of received data sent out
the connector. Data transmitted over the air by the

radio is unaffected by the

sible average latency. Data bytes are sent out the
as soon as an incoming RF data frame is disassembled. Average and typ-
ical latency will both be below 10 ms, but idle character gaps may be
introduced into the outgoing data flow.
If data buffering is

is, 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 25 to 50 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™ that do not allow gaps in their data transmission.
Note that seamless mode (
where the transmitter's baud rate is greater than or equal to the
receiver's baud rate. Enforcement of this rule is left up to the user.
Changes to the setting may only be made at the master radio. This
BUFF
is because the master radio broadcasts the buffer setting for the entire
network. At remote radios, the buffer setting may be read when the radio
is in synchronization with the master, but it may not be changed.
CTS [0–255]
The (clear-to-send) command sets or displays the timer value asso-
CTS
ciated with the CTS line response. The command parameter ranges from
0 to 255 milliseconds.
