Configuring NetRef Settings (CTPView)

Port Providing Reference

Specifies whether you want to enable or disable the NetRef primary node to function as the reference port providing frequency for clock synchronization.

You need to specify this value for the 1st Priority Reference 0, 2nd Priority Reference 1, 3rd Priority Reference 2, 4th Priority Reference 3, and 5th Priority Reference 4 fields to specify the reference clocks for the primary nodes with corresponding priorities.

Select Yes or No to enable or disable the primary node to function as the reference clock.

Reference Frequency

Specifies the frequency to be used for the reference clock or the primary node.

You need to specify this value for the 1st Priority Reference 0, 2nd Priority Reference 1, 3rd Priority Reference 2, 4th Priority Reference 3, and 5th Priority Reference 4 fields to specify the reference clocks for the primary nodes with corresponding priorities.

Select a reference frequency in the range from 32 Khz through 4096 KHz; or 1 MHz, 5 MHz, or 10 MHz.

You can configure the CTP systems by using the menu interface or by selecting CTPView Node Synchronization to provide multiple prioritized node clock references. An external reference input and any of the serial interfaces may be used for the node reference clock. Reference frequencies must be 32 KHz, 1544 KHz, 1 MHz , 5 MHz, 10 MHz, or n x 64 KHz <=4096 KHz (2048 KHz maximum on the CTP1002).

NetRef: Slave

Specifies the client node for which multiple primary nodes are associated for receiving clock synchronization information.

Select the client node to be locked to the different primary nodes.

Master IP (Priority # 1)

Specifies the IP address of the primary node with priority 1.

Enter the IP address of the primary node with priority 1.

Master IP (Priority # 2)

Specifies the IP address of the primary node with priority 2.

Enter the IP address of the primary node with priority 2.

Master IP (Priority # 3)

Specifies the IP address of the primary node with priority 3.

Enter the IP address of the primary node with priority 3.

Master IP (Priority # 4)

Specifies the IP address of the primary node with priority 4.

Enter the IP address of the primary node with priority 4.

32 kHz Reference Output

Specifies whether you want to enable the reference output signal.

Select the Enable check box if it is already disabled.

Clock Main RTM

Specifies the clock rear transition module (RTM) used to input a reference clock into the CTP2000 platform.

Select a value from the Port DB25 drop-down list to use clock module RTM.
