Teamwork Networking
NOTE
•
All smart cooling products in a teamwork group must be of the same model.
•
Do not directly connect the first and the last smart cooling products to form a ring network.
•
A maximum of 32 NetCol8000-Cs are supported. In a teamwork communication, the cable
length of two adjacent smart cooling products must be shorter than 10 m.
Teamwork Networking and Monitoring
1. When the host monitors smart cooling products using the RS485 protocol, the time needed for
collecting all data from a single smart cooling product is 3 seconds. In the teamwork mode of
cascading using an RS485 bus for monitoring, it takes the host 3 seconds multiplied by N to
collect data from N smart cooling products in the group. For example, the time needed for
collecting data from four smart cooling products is 12 seconds. If the host needs more time to
collect data from all smart cooling products than what the host performance requires, use the Y-
split cable connection scheme shown in the following figure.
2. The following figure shows the scenario where every two smart cooling products connect to the
host computer over a Y-split cable. Determine the number of Y-split cables used for grouped
monitoring based on performance requirements.
