SECTION II
INSTALLATION
2-1. GENERAL INFORMATION.
Section II
Section II contains information relating to installation and input connections.
2-2. RACK MOUNTING.
If the recorder is to be rack mounted, be certain to allow sufficient open space
for cooling air to enter and exhaust.
Do not rnount the recorder next to equip-
ment which will discharge hot air into the recorder air intake.
2-3. CONNECTION TO THE
$p
TRANSISTORIZED COUNTERS.
The recorder may be directly connected to the ~ transistorized counters by
means of the input cable supplied with the recorder.
The transistorized
counters have the correct connector installed.
Recorder connector J101 is
connected to the counter recorder connector.
If a second transistorized
counter is to be connected to the recorder, connection is made froIn the second
counter to recorder connector, J201.
The transistorized counter output is
+1224 BCD.
2-4. CONNECTION TO
rfiJ
COUNTERS AND DIGITAL VOLTMETER.
If the recorder is to be connected to the above tube type instruments a modifi-
cation kit can be installed.
The kit provides a +1224 BCD output.
2-5.
OPERATION FROM TWO DATA SOURCES.
The recorder can be operated fronl two data sources, synchronized or unsyn-
chronized, by connecting the data inputs to connectors J101 and J201.
The two
data inputs can be ±1224 or ±1248 code.
The appropriate coluInn boards Inust
be installed in the proper connectors in the recorder.
2-6. CABLE FABRICATION.
Connection of the recorder to data sources other than the above Inay require
construction of a cable terminated with a connector that will mate with the
recorder connectors.
Use small gage telephone-type wire.
Number 26 gage
wire meeting MIL-B -76A, with 7 strands #34 gage wire, tinned after stranding,
with 10 SoC plastic insulation has been found satisfactory.
Select a sy stematic
color code for wires to avoid errors.
Use care in soldering. Repairing faulty
connections after all wires are soldered is very difficult. A length of # 14 gage
wire makes an excellent soldering tip for use on closely-spaced connector terrninals.
