3.7.1. Configuring The Serial Port Mode
GENERAL
SERIAL PORT
MODE
Port normal
Port synchro rx
Port synchro tx
Port synch time
Port status dump
Port status get
This menu item sets the mode of operation of the COM serial port.
When the
SERIAL PORT MODE
is set to
normal
the COM serial port is
used for firmware upgrades only (see section 4.2).
When the
SERIAL PORT MODE
is set to
synchro tx
the COM serial port
can be used to send configuration commands to another 5600MSC
operating in the s
ynchro rx
mode. This application is used where there are
two 5600MSC units tied together through a 5600ACO Auto changeover and
you want to ensure that the menu settings of both units are always the
same. See section 2.4 for information on connecting the two 5600MSC
units together. There is normally a cable supplied with the 5600ACO
changeover unit to interconnect the units.
When the
SERIAL PORT MODE
is set to
synchro rx
the COM serial port is
used to receive configuration commands from another 5600MSC operating
in the s
ynchro tx
mode. All menu parameter displays will be shown with the
display brightness dimmed to indicate that the unit is operating as a slave of
another 5600MSC units. You will be able to view the menu settings but not
change most of them. You can also set the
TIME REF
to
Synchro time ref
.
to reference the 5600MSC system time to the other 5600MSC that is
connected and running in
synchro tx
mode. See section 3.5.2. A note here
on GLOBAL PHASING. When the Frequency Reference is set to internal or
10MHz, the GLOBAL PHASING controls are ignored by the syncro, and
may be set in the RX unit to a different value to the TX unit.
When the
SERIAL PORT MODE
is set to
sync time
the COM serial port is
used to receive time information only from another 5600MSC operating in
the s
ynchro tx
mode. Configuration parameters received from the other
5600MSC will be ignored. You will also have to set the
TIME REF
to
Synchro time ref
. to reference the 5600MSC system time to the other
5600MSC that is connected and running in
synchro tx
mode. See section
3.5.2.
When the
SERIAL PORT MODE
is set to
status dump
the current settings
of all the controls are output on the COM serial port in human readable text
and may be viewed by a standard terminal program such as HyperTerminal.
There is also a set of hex strings which are computer readable. See section
4.2.2 for information on connecting the computer and setting up the terminal
program. This can be stored for later retrieval.
When the
SERIAL PORT MODE
is set to
status get
5600MSC is waiting for
data to come in via the COM serial port. It expects the hex strings which
were produced by a status dump. All other data is ignored. This can be
used to recover settings that were output by a 5600MSC using the
status
dump
. When the 5600MSC receives packets, it will pop up 1 second long
messages indicating what type of information it has received. For instance,
“GOT SYNC 1” or “GOT GENERAL”.
