5.2  Precautions for wiring communication

 

 

Communication wiring 

Communication cables that are used for connecting the product to 
user’s equipment are not included. Use the following cables. 

100BASE-TX 

 

Shielded twisted pair cable (STP) or non-shielded twisted pair cable 
(UTP) with category 5 or more 

10BASE-T 

 

Shielded twisted pair cable (STP) or non-shielded twisted pair cable 
(UTP) with category 3 or more 

 Use straight cables for the twisted pair cable. 

 

5.3  Connected explanation 

Fig. 5-1. Shows the connection with customer equipment. 

 

 

 

Fig. 5-1 Connection with the base 

 

One Point

 

Connect Thermo chiller with the base device via a hub.   

Cables,  connectors  and  hub  shall  comply  with  the  IEEE802.3 
10BASE-T/100BASE-TX standard. 

Up to 4 customer devices can be connected at the same time.
