3.3.2.4 Main Menu 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.

Tap

[Set Data] to save the updated configuration selections. Otherwise, tap [ok] to return to the

Main Menu 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.
