second. The stored status can later be recalled by briefly pressing the same button. Memory banks an easy
way to quickly change complex antenna selection assignments.
NOTE: Updating the configuration of SMD from Router will reset all items in the non-volatile memory and all of
the memory banks to their default state.
Events that may occur when attempting to transmit
While transmitting, the TX path status is displayed above name
of TX antenna path (LCD display, pos.9). Several events may
be indicated:
ON-AIR
•
This is the normal, TX-in-progress, state.
ERROR
•
This indicates a permanent error, usually a missing or invalid TX path.
BUSY
•
This indicates a transitional reason for TX inhibit, for
example a SteppIR antenna is tuning or the tamper
input on a module is active.
KEYIn
•
This indicates that TX inhibit is raised as long as a PA
present in TX path is not ready to transmit.
In the same setup, after a successful start of transmission, the
KeyIn signal went inactive, e.g. due to excessive SWR.
If band locks are configured (Router, Configuration Management -> Security), several messages may be
displayed as consequence of attempted TX on a shared band.
If "Detach RX antenna" protection is selected, the message
"BOX [nr of other SMD] - bandlock RX (or RX2)" is displayed
on the SMD receiving on a band where other SMD started to
transmit, while its RX path is disconnected. If the offending
SMD subsequently leaves this band, a "BOX [nr of other SMD]
- left RX (or RX2) band" message is displayed.

In addition, some specific, permanent reasons for TX disable
may result in more descriptive messages - "INHIBIT raised",
"KeyIn timeout", etc. - and the number of the offending unit
where appropriate.
If "Prevent TX" protection is selected, message "BOX [nr of
other SMD] - rejected PTT" is displayed on the SMD
attempting to transmit on a shared band.
83
When attempting to transmit, an error occurred, as indicated
by "ERROR" displayed below the TX frequency. Additionally,
the reason of error is displayed in the top line - here, no valid
TX antenna was selected prior to PTT.
When attempted to transmit, a PA controlled directly from
SMD (rather than from a networked module) failed to assert
KeyIn within a set time slot, potentially indicating a
permanent problem.
