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.
