3 D104 4-CHANNEL RS232 SWITCHING UNIT
3.1 GENERAL DESCRIPTION
The D104 switching unit is designed to link up to four OptoRS simplex or duplex instruments to be connected to unit
D100S, or, by connecting several D104 units in parallel, up to 16 instruments. The D100S unit automatically reads the
values measured by the Sylvac RS232 instrument and processes them in the same way as a value measured by a
probe.
The D104 unit may be fixed to the D100S by inserting four plastic legs. It may also be installed separately, close to
OptoRS instruments (maximum RS232 connection distance is 15 meters).

3.3 OPERATION
- The OptoRS simplex or duplex instruments are connected to inputs 1 to 4 of the D104 unit and correspond to chan-
nels 1 to 4 on the display.
- If a second D104 unit is used, the inputs marked 1 to 4 on this unit correspond to channels 5 to 8 on the display.
This second unit will be connected in the same way as above: the 'Extension' input/output of the first D104 unit is
connected to the 'RS232' input/output of the second D104 by means of the 9p. male cable supplied. It is also neces-
sary to connect the 'Out' output of the first D104 to the 'In' input of the second D104.
- Configure the OptoRS channels by pressing Setup then Channel, then type in the OptoRS channel number followed by
Enter, then Enter if the channel is allocated to the OptoRS instrument connected to this channel number, then 2 for OptoRS
simplex instruments or 3 for duplex.
- It is now possible on the D100S display unit to enter presets, tolerances, choose the direction of measurement and the
radius/diameter mode for each channel. Once this has been done, it is possible to select manually the channel to be
displayed, and to change channels by means of the external contact (foot pedal) if this has been configured to do so.
These functions are explained in detail in Section 1.6.
