4.1.1 T̲e̲s̲t̲ ̲w̲i̲t̲h̲ ̲O̲p̲t̲i̲c̲a̲l̲ ̲M̲o̲d̲e̲m̲
The Delta Data terminal is via the internal FIBER OPTIC
MODEM connected through a 2 Km long twin fiber optical
Cable to a secondary optical modem, which is through
a V24-Cable connected via test-set 921T to the communication
tester 834. See fig. 4.1.1-1.
4.1.2 T̲e̲s̲t̲ ̲w̲i̲t̲h̲o̲u̲t̲ ̲O̲p̲t̲i̲c̲a̲l̲ ̲M̲o̲d̲e̲m̲
The Delta Data terminal, delivered with no internal
Fiber Optic modem, is through RS232 connector and via
Test-set 921-T connected to the communication tester
834. See fig. 4.1.2-1.
4.2 M̲A̲I̲N̲S̲ ̲I̲N̲P̲U̲T̲
4.2.1 A̲d̲j̲u̲s̲t̲a̲b̲l̲e̲ ̲I̲n̲p̲u̲t̲ ̲S̲u̲p̲p̲l̲y̲
To facilitate voltages and frequency variation test
of the Delta Data terminal, the mains input is supplied
via an ABACUS Frequency stabilizer which is altered
to a manual variable unit by swopping the control module
with option board 233-5 and connecting an auxiliary
control box.
4.2.2 M̲e̲t̲h̲o̲d̲ ̲o̲f̲ ̲I̲n̲p̲u̲t̲ ̲C̲o̲n̲t̲r̲o̲l̲
Module assy 40804 in the ABACUS Frequency stabilizer
is swopped with option board 233-5.
ON option board 233-5 is the voltages control for the
frequency oscillator IC6 and the voltage control for
the voltage stabilizer IC1 connected to the end-connector.
By connecting two auxiliary potentiometers to the relevant
4 pins on the end-connector it is possible to vary
the voltages output between 180 to 260V, and to vary
the frequency of the output between 45Hz to 65Hz.
The two potentiometers are mounted in a small adequate
box and through a five-core cable connected to the
end connector of the ABACUS unit.
By means of a Voltmeter and a frequency counter is
the two control Knobs of the potentiometers scaled
in Voltage and frequency.
