For the coupler type, it is required for the user to enter a coupler number for
setting [Coupler No_CH*]. Remind that the same number must be entered on
both sides of the coupler, when two CHs are assigned for it. Figure 2.1-5
illustrates an example that the same coupler number '1' is set for CH1 and CH2;
similar means is employed for the other settings. As there is no rule for
numbering the CHs, so it is possible to choose preferred numbers for the CHs.
