DESCRIPTION:
The CNSC-1 A and CNSCI-1 A Slide Control Units interface to a CRESNET II control system
over the CRESNET II network. The CNSC-1 A (CNSCI-1 A) can be configured to provide
control for Kodak Ektagraph, Kodak SA V, SIMDA and Electronic slide projectors.
Configurations are factory set, but may be field-altered .
The CNSC-1 A (CNSCI-1 A) also accepts five input closures. The inputs are connected to 5
VDC via 10K ohm pull-up resistors and are referenced to system ground. A contact closure
to ground, as well as an open collector type signal, is detected as an input. Therefore, an
input low causes the associated signal name to go high. Input selections
< i1 to i5 > are provided via the 6-pin connector. When the AC OUT switch on the front of the
unit (SW in the preceding schematic) is pressed, the signal associated with < i6 > is
momentarily driven high.
Each slide control unit on the CRESNET II network requires the setting of an identity code
(ID CODE). ID CODES are two-digit hexadecimal numbers, from 10 to FE. The ID CODE
of the unit should be set to match the ID CODE specified in the NET .ID statement of the
CRESNET II SIMPL-C program referencing the unit (see syntax above). To set an ID
CODE, disconnect power and network connections and turn the unit so that the back faces
you. Notice two miniature rotary switches identified as HI and LO. These 16-position
hexadecimal switches can be set to 0 through F. Using a small screwdriver, rotate the arrow
in the center of the switch marked HI point to the first (or most-significant) digit or letter of
the specified ID CODE. Set the switch marked LO to the second (least-significant) digit or
letter of the specified ID CODE.
The 4-pin connector marked NET should be wired to the CRESNET II network. Network
termination points are available at the control system power supply. Network units may also
be daisy-chained together. See the CRESNET II manual section on CNPWS power
supplies (Doc
