2.1 Data Acquisition Camera (DAC) (SEB33100100):

The 16 mm. Data Acquisition Camera (DAC) is used to obtain

sequential photographic data during manned space flightmissions. Unlike typical movie cameras, this unit has

independent shutter speeds and framing rates. Furthermore,the automatic frame rates are lower than the common cine

speeds to maximize film usage while maintaining the desired

engineering data value. The DAC can be handheld or bracket

mounted, can operate from spacecraft or portable battery

power, and can accept various lenses and assorted accessories

as described in the following sections of this handbook.

2.1.1 Significant Configurations:

Configuration Purpose

-211 Skylab flight unit; 2 fps mode

instead of 1 fps ~

-216 Skylab support unit; 2 fps mode

instead of 1 fps

-217 Apollo CM and LM flight unit

-218 Apollo lunar surface flight unit;operate light hood incorporated

2.1.2 Characteristics:

- Manufactured by J. A. Maurer, Inc., Long Island City,New York 11101.

- weight - l.7 lbs (771 g.)Envelope - 6 X 3.75 X 2.u in. (15.2 X 9.5 X 6.1 om)Volume - 5M in3 (885 cm3) X

- Power requirements: 28 i M VDC at 0.6 amps nominal from

spacecraft or DAC Power Pack (see 2.17). DAC incorporatesself-resetting overload protection circuit and replaceablepower 1ine fuse (1.5 or 2.0 amp) (see 2.15).

'

Sequencing frame rate settable to 1 (or 2), 6, 12, or

2M frames per second (fps) and time exposure.

Automatic Modes [1 (or 2), 6, and 12 fps] are initiated

by depressing and releasing camera front button and continue

uninterrupted even if sequencing rate is changed amoung

automatic modes. Camera operation is stopped by depressingand releasing frontbutton. or by switching to the time

exposure or 2M fps mode settings. Green operate light will

flash at frame rate.

2M fps operation starts when front button is depressedand stops when button is released. Green operate lightilluminates almost constantly.

TIME exposure is started when front button is depressedand released only if (l) camera was previously stopped byfront button method, (2) mode is set to TIME, and (3) shutter

speed is set to l/60 second. Time exposure is ended by depres-sing and releasing the front button. Green operate light will

flash once as the shutter closes.

'

5 mm. Lens (SEB33lOOO56):

This is the widest field-of-view lens available for the DAC

system. It is used primarily for interior photography when

maximum area coverage is desired and where detail and geo-

metrical fidelity are less important. Even though the barrel

distortion effects of this lens are minimal for a lens of

such short focal length, the effects are noticeable.

10 mm. Lens (SEB331000l0):

The 10 mm. Lens has a wide field-of-view, a large relative

aperture, and very good resolution and distortion character-

istics. The lens is most useful for interior vehicle

photography where illumination is low and where moderate

engineering detail is to be recorded. The low distortion

property of this lens has made it well suited for recording

EVA and lunar surface operations also.

Cable incorporates a Deutsch type URA6-8-TP bayonet con-

nector for attachment to the DAC or the Hasselblad camera

accessory connector.

'

For DAC control, the camera operation can be started and

stopped and the camera sequencing modes can be selected

as follows:

Configuration Sequencing Modes

-301 l, 6, l2, and EM fps

-302 1, 6, 12, and 2M fps

-303 Time, 1, 6, 12, and EU fps

-305 Time, 2, 6, l2, and QM fps

Remote mode selection is independent of camera mode

selector switch setting. The camera operating mode is

2.16-l

determined by which operate button is used to start the

sequencing. DAC automatic operation can be stopped bydepressing and releasing either operate button.

For Hasselblad camera control, only camera actuation can

be triggered with the cable button. Remote mode selectorsetting has no effect in this case.

The cable configurations -301 and ~302 incorporate an

indicator lamp under the operate button. This lampflashes at the selected sequencing rate. The lamp opera-tion capability requires some wiring modifications in theDAC itself and eliminates the TIME mode.

The Remote Control Cables are qualified for use in theApollo and Skylab vehicles.

;_§~M `

fs _

Incorporated cable connects to DAC power connector (forward-most). Cable connector is a Bendix JTO6A-8-63 bayonet type.

The -303 pack connector incorporates a metal_tab assembly to

assist EVA gloved connection of cable to DAC. The total

cable/connector length is 7.5 i 0.5 in. (l9.05 i l.3 cm.).

The mounting rail of the -303 configuration attaches the

pack to the DAC Handle (see 2.20). One mounting rail of

the -305 configuration attaches to the DAC EVA Bracket

(see 2.l9) and the other to the Universal Mount (see 2.l8).

The Power Pack has been qualification tested for use in

the Apollo and Skylab vehicles and during EVA operations.

Universal Mount (sEc39io6239)=

As the name implies, the Universal Mount (UM) can be used to

mount many different items in the Skylab SWS operations.For photographic operations, the UM can be used to mount the

DAC,the>HighIntensity Light, and the 35 mm. Nikon camera

(see 3.1 .
