HOPTIME [7, 14, 28]
Radio Transmitter Hop Timing
The HOPTIME command is used to set or display the hop-time setting. The
command is a digit corresponding to the hop-time setting in milliseconds. The
default HOPTIME setting is 7. A setting of 28 must be used when throughputs
exceed 57,600 bps and is recommended when data transmission sizes exceed
256 bytes.
Changes to the HOPTIME setting may only be made at the Master radio. (This
is because the Master radio establishes the hop-time setting for the entire
network.) At Remote radios, the hop-time setting may be read when the radio
is in synchronization with the Master, but it cannot be changed.
INIT
Initialize; Restore to Factory Defaults
The INIT command is used to reset the radio’s operating parameters to the
factory defaults listed in Table 12 on Page 34. This may be helpful when
trying to resolve configuration problems that resulted from the entry of one
or more improper command settings. If you are unsure of which command
setting caused the problem, this command allows you to get back to a known
working state.
NOTE: Caution should be exercised when using the INIT command on radios in a sys-
tem employing the Store-and-Forward feature. Settings relating to the use of Ex-
tension services will be lost and will need to be re-entered. Record the settings
for XADDR, XPRI and XMAP before using the INIT command.
SPECIAL
NOTE: Installing firmware of Revision 3.0 or later into a radio with Revisions 1.x firm-
ware will preserve the radio’s compatibility with other radios running Revision
1.x firmware. If updating the radio’s firmware is part of a system-wide upgrade,
the last step should be to use the INIT command at the Master station. Use of
the
INIT command causes the changes shown in Table 12 to be applied.
