Set Data Transmit Delay
Essentially this is the
pt
command and when used in conjunction with the
minimum
data length
parameter, sets the amount of time from the receipt of a first byte of data
from the host until the radio will transmit in transparent mode. Default is
00H
which
causes transmission to occur without any delay. When a host is sending a group of
data that needs to be sent together, setting this parameter will provide time for the
group of data to be sent by the host before the radio transmits. If the length of data to
be sent together is longer than the time slot can send, the data will not be sent together
but will be broken up over multiple hops. The length of time the radio will wait is
equal to the specified value times the hop duration.
NOTE: The Transmit Delay is specified as a number of hop durations and thus will
be an integer multiple of the Hop Duration. The Maximum Base Packet can only
be set in radios set as a base. If the radio is a remote, this value cannot be changed.
Maximum Base Packet (base station only)
This is the
pw
command and sets the amount of time allocated for transmission on
each hop for the base station time slot in 4-byte increments. If using a protocol mode,
attempting to send a packet with a length longer than this setting will cause the packet
to be discarded.
Set Minimum Data Length
This is the
pk
command and sets the minimum threshold number of bytes required to
form a packet in transparent mode. The radio will wait until the data transmit delay
elapses before sending a data packet with less than this number of bytes. This
parameter can be used to keep short, intermittent transmissions contiguous. In packet
modes, the length parameter in the data packet will override this value. This value is
subject to the maximum data length even in packet mode.
