SUMMARY ALARM
REMOTE
AUTO
PSU OK
Rear panel connections
The connections made at the rear of the chassis are made according to whether the unit is a RCU100 1:1 or
an RCU200 1:2 system. With an RCU100 some of the connectors are not used and are blanked. The RCU
connectors differ from previous models and all connectors are now SMA type instead of a mixture. The
switch arrangements one side to another on the rear are identical and theoretically interchangeable A for A, B
for B etc. Converters are switched on both inputs and outputs and switches are rated to 18GHz.. Refer to the
scheme below relative to the product and use and drawings at the end of this manual.
Issue 3.15
2 position switch which selects remote control from external computer system or
internal control for selection and setting of the system
In REMOTE position the other selection switch is disabled
This 3 position switch selects which unit or units are to be on line.
In positions A and B the selection is fixed and can only be over-ridden by
selecting REMOTE. In AUTO the ONLINE LEDS on the converters should be
observed to determine the status of the system.
RCU100. If position A is selected the unit designated A by the position of the
INTERFACE connector at the rear of the units is selected and put on line.
Similarly of position B is selected B will be put on line. In AUTO the alarms of
the units are monitored and switching is automatic. The unit first selected is the
one last selected with A or B.
RCU200. If position A is selected the unit designated A by the position of the
INTERFACE connector at the rear of the units is substituted for the STANDBY
unit which is put on line. Similarly of position B is selected the STANBY unit is
substituted for unit B.
If a non selected unit is in alarm any change-over will not take place.
When REMOTE is selected the unit will still automatically switch (if AUTO had
been selected when the unit was switched to REMOTE) even though the
A/AUTO/B switch is disabled.
Lit GREEN when status of 5 Volt supply is OK
Normally lit GREEN but will turn RED with any internal unit failure or external
unit failure
Lit Green when in REMOTE mode
Lit Yellow when in AUTO mode. Flashes once when unit A is selected. Flashes
twice when unit B is selected .
PSU Failure - cuts power to internal coaxial switch to prevent unwanted 'grey'
switching
