indicates safety information.
CAUTION:
EVEN WHEN THE POWER SWITCH IS IN
THE OFF POSITION, A SMALL CURRENT
FLOWS THE FILTER CIRCUIT.
CAUTION:
THE AC OUTLET (MAINS SOCKET) SHALL
BE INSTALLED NEAR THE EQUIPMENT AND
SHALL BE EASILY ACCESSIBLE.
THIS APPARATUS MUST BE GROUNDED
To ensure safe operation the three-pin plug must be
inserted only into a standard three-pin power outlet
(socket) which is effectively grounded through the
normal household wiring.
Extension cords used with the equipment must be
three-core and be correctly wired to provide
connection to the ground. Incorrectly wired extension
cords can be extremely hazardous.
The fact that the equipment operates satisfactorily
does not imply that it is grounded, and the installation
is not necessarily safe. For your safety, if in any
doubt about the effective grounding of the equipment
or power outlet (socket), please consult a qualified
electrician.
Operating precaution
Operation near any appliance which generates
strong magnetic fields may give rise to noise in
the video and audio signals. If this should be the
case, deal with the situation by, for instance,
moving the source of the magnetic fields away
from the unit before operation.
CAUTION:
TO REDUCE THE RISK OF FIRE OR SHOCK
HAZARD, REFER MOUNTING OF THE
OPTIONAL BOARD AND CHANGE OF
SWITCH SETTINGS INSIDE THE UNIT TO
QUALIFIED SERVICE PERSONNEL.

Contents
Thank you very much for purchasing this AJ-BS901 Base Station (referred to throughout these instructions as “the unit”).
The unit is used together with the AJ-CA901 camera adapter and connected to a DVCPRO50 camera recorder to configure a
transmission system which uses a tri-axial cable to enable the camera recorder to be operated as a system camera.
Use of non-compressed wide-band 360 Mbps serial component signals makes high picture quality transmission possible so
that the high picture quality of the images shot by the DVCPRO camera recorder are transmitted with their high picture quality
kept intact.
This serves to expand the range of the DVCPRO camera recorder’s operating formats.
Note
≥When the unit is connected, external input signals cannot be recorded on tape inside the camera recorder.
“CAM” must be selected as the REC SIGNAL setting on the SYSTEM SETTING menu of the camera recorder.

Features
The unit has the following features.
≥It enables high picture quality transmission by means of non-compressed wide-band 360 Mbps serial component signals.
≥It uses a tri-axial cable.
≥It enables a DVCPRO camera recorder to be operated as a system camera.
≥It enables the transmission of the signals of two audio channels.
≥It enables RET 1CH and PROMPT 1CH transmission.
≥It has a compact size equivalent to one-half of a rack unit.
≥It can also be operated using DC power.
≥It can perform the VTR operations of the camera recorder.
Bear in mind the following checkpoints when connecting the camera recorder to the unit’s system.
1When using this unit with a system to which a camera recorder is connected, an AJ-SDX900 model must be used for this unit
to function.
Depending on the version of the software being used with the camera recorder, it may be necessary to update it, in which
case you should consult your dealer.
2The triax and ECU (extension control unit) cannot be used at the same time for the camera recorder.
3When the triax is connected, some of the settings (such as GAIN, CAM-BAR SW, WHITE BAL, SHUTTER and USER SW)
selected by the switches on the camera recorder will not take effect.
4When the triax is connected, the composite video signals (MON OUT, VIDEO OUT) of the camera recorder will be non-
standard signals.
