Preparation for Communication

HEC 1-1

1Preparation for Communication

Make preparation for using communication facility as follows.

1) Turn off the power switch of Thermo-con.

2) Connect communication cable to communication connector (RS-485 of RS-232C) of Thermo-con.

･Use twist pair shield cable as communication cable.

･Connect the host and thermo-con with the cross cable for RS-232C and the straight cable for RS-485.

･Connect shielded cable of communication cable to communication connector and drop it to FG(flame

ground).

･Connection drawing for communication is shown in the Figures 1-1 and 1-2.

･Length of communication cable for RS-485 shall be limited to around 500[m] in total, and that for RS-

232C shall be 15[m].

･If communication cable for RS-485 is longer, connect terminating resistance (220Ω,1/2w) to each ＋

and －terminal of the host computer and the farthest Thermo-con.

3) Turn on the power switch of Thermo-con.

4) Select communication types for all Thermo-cons. See the operation manual of the details.

5) That’s all for preparation of communication. Then if a communication command from the host

computer is given, each Thermo-con will reply it.
