Æ Configuration Æ Miscellaneous
The currently selected transceiver is the unit that will be modified in the
Miscellaneous
configuration
XCVR#
selection box:
XCVR1
is the default selection and
XCVR2
is not selectable if CiLink is set to operate under
standalone (non-redundant) system parameters (see
Configuration
Æ
System Type
for detailed
information).
The status-only
ONLINE/OFFLINE
field to the right of the
XCVR#
selection box indicates the active line status of the currently
selected transceiver.
• Cold Start [On/Off] ▼ – The transceiver provides an
optional ‘
Cold Start
’ feature that ensures that the internal
10 MHz reference signal is at a stable temperature prior to
allowing the RF and IF outputs to be turned on. A fixed
cold start interval of 15 minutes is used. At the end of the
15-minute interval, the RF and IF outputs automatically
turn on, providing all fault conditions and appropriate
settings are met. If a transceiver was powered on with
Cold Start: On
, the operator can override this function by
selecting
Cold Start: Off
.
• Auto Fault Recovery (AFR) [On/Off] ▼ – This parameter defines how the transceiver
responds to momentary fault conditions. If
AFR
is
Off
and a fault condition occurs that
causes the RF or IF output to be muted, then that fault condition clears and the transceiver
will remain muted. If
AFR
is
On
, and the same situation occurs, the transceiver will
automatically be unmuted and return to normal operating mode. To protect against
repetitive momentary faults, if the transceiver experiences five occurrences of the same
fault, the
AFR
parameter will automatically be set to
Off
.
• Local Ref Osc Adjust – A fine adjustment of the internal 10 MHz frequency is provided as
a user controllable parameter. This parameter can be varied within the range of 000 to 255.
• Ext Ref Present
status only – If an external reference is connected to the transceiver, this
parameter will display the status of the signal.
• Ext Ref Fault Logic [Enable/Disable] ▼ – The transceiver allows the user to select
whether or not the summary fault relay is activated if the internal 10 MHz reference loses
lock with the external reference attached to J4 ‘EXTERNAL REF IN’ port.
• Up/Dn Conv Slope Adjust – The TX and RX channel slopes can be adjusted from 0.0
(factory setting) to 1.0 in 0.1 steps. 1.0 corresponds to approximately 2 dB of positive slope.

the updated configuration selections. Otherwise, tap [ok] to

from the
Configuration Æ Miscellaneous screen without saving any changes.
IMPORTANT
The Cold Start and AFR settings can only be changed if the currently
selected transceiver is ONLINE.
