Slot Module Unit Description
1 KS3655 0 KS 3655 8-Channel Timing Generator
Current users of spec have made the following modifications
to the Kinetic Systems Model 3655 Timing Generators. This timing
generator is customarily used with the Kinetic Systems Model 3610
Hex Scaler. All modifications are made on the component side
of the board.
Bring the internal 1 KHz timing signal out through
the channel 7 front-panel lemo connector. Do this by first
unsoldering the end of the wire that connects the center pin of
the channel 7 lemo connector from the feed through on the circuit
board. Do not unsolder the wire from the connector, as it
will be difficult to solder on a new wire. Instead splice a
longer wire to the one already attached to the connector and solder
the other end of that wire to pin 11 of chip BJ. (Pin 11 is the
center pin on the front-panel side of the chip.)
Disconnect the internal inhibit signal from the CAMAC
dataway, and bring it out through the channel 8 lemo connector.
Do this by folding up and/or snipping pin 6 of the socketed 7407
chip in position BX, near the front panel. Next either fold up
pin 3 of chip AU or cut the long trace that leads from that pin
to the dataway Inhibit connector. Then solder a wire from pin 3
of chip AU to the bottom lead of resistor R45. The resistor is
located near the top-right corner of the circuit board, and the
bottom lead is the one nearest the letters R45.
Channel 7 is then connected to channel 0 of the scaler module,
while Channel 8 is connected to the inhibit input.
The signal from the source of monitor counts is connected, using a
tee, to the clock input of the 3655 and the monitor
scaler channel (usually channel 1; the detector is usually channel 2).
