How you access this window is based on whether or not you have already
configured the port.
• For an unconfigured FT1 link module
The first time you configure a port, the Edit FT1 Clock Parameters window
opens automatically. When you set these clock parameters, you define the
timing sources for the selected port only.
• For a configured FT1 link module
Display the FT1 Port Parameters window (FT1 Connector > Edit Logical
Lines > Port Details > FT1 Port Parameters).
To set the clock parameters:
For the primary or secondary clock, you can set the value to Internal to use the
clock chip on the link module. Otherwise, you can set the value to Port 1 Ext Loop
so that the clock uses the signal coming in from port 1.
