Gilderfluke&Co Quad D/A and Single Channel D/A - Manual (Page 2)

- SINGLE CHANNEL D/A CONNECTIONS -
The single channel D/A converter gets it's data and power through a single 1/4 J-6 data cable. The
output is available on a 5 position molex connector on pins #1 and #3. Pin #2 is removed to be used
for a polarizing key if desired. If an external power supply is needed, it is attached to pins #4 and #5 of
the molex connector.

If you need to optically isolate the analog output from the rest of the control system, cut the
1N4001 diode closest to the 1/4 J6 connecter and pin #1 of the 1/4 J6 connector (this is easiest to do
on the back of the J6 connector, rather than on the front). In this configuration you will need to use an
external power supply for the D/A.
A single channel D/A converter can be mounded by screwing it to where it is needed. Standoffs
should be used. A small card cage can be used when you need to hold a number of single D/A convert-
ers.
The Single Twelve Bit D/A converter is identical to the Eight Bit Single D/A converter except that its
twelve bit resolution gives it 4096 steps of resolution instead of 256. Twelve bit analog channels take one
and one half eight bit channels (twelve bits worth of data). The arrangement of the data within these
channels is as follows:
base Channel 00h (bits 0-3 = output 1’s lower 4 bits, bits 4-7 = output 2’s lower 4 bits)
base+01h Channel 01h (analog output #1 MSB)
base+02h Channel 02h (analog output #2 MSB)
base+03h Channel 03h (bits 0-3 = output 3’s lower 4 bits, bits 4-7 = output 4’s lower 4 bits)
base+04h Channel 04h (analog output #3 MSB)
