Note that if you have configured an IDAS, you will see both SuiteLink and HCAL connections used by the IDAS.

Connections using the HCAL (Classic) protocol

Connections use the HCAL (Classic) protocol for the following reasons:

  • The connecting system uses older software.

  • The connecting system is on current software, but the connection uses a legacy port. Update the connection to point to the port for current HCAL protocol (32565 by default).
