Glossary

Scanning When a facsimile broadcasting is received and recorded, the recording of the
received image starts one dot by one dot from the left end of the paper.
When the recording reaches the right end, it is returned to the left end of the
paper again and the same operation is repeated until the image recording is
completed. This operation is called “scanning”.
Primary scanning Scanning in the horizontal direction as shown above
Secondary scanning Scanning in the vertical direction as shown above
Scan line density The number of scan lines plotted while the paper moves one millimeter in the
secondary scanning direction during the recording of received signals.
Scan speed Primary scanning speed: for example, 120 primary scannings per minute are
performed at 120 spm (scan per minute).
Index of cooperation
(IOC)
If the paper size transmitted from a broadcasting station is different from the
recording paper size on the receiving side, it is necessary to equal the vertical
and horizontal reduction or enlargement of the original paper to keep a similar
figure. The coefficient to keep a similar figure between transmitting and
receiving sides is called “index of cooperation”.
Halftone recording This is a method of displaying the contrast of clouds in recording cloud photos
taken by a meteorological satellite, in which the contrast is displayed by the
difference in the density of black dots like in a black/white photo in a
newspaper. It is indicated as HALF in this manual.
Start signal Start signal is the signal transmitted at the beginning of the facsimile
broadcasting to indicate the start of the broadcast.
JAX-9B uses it for the automatic setting of the index of cooperation (IOC) and
starts the automatic recording by receiving this signal.

Glossary
xii
Phase signal Phase signal is the signal transmitted next to the start signal. It is indicated at
the both ends of the image when synchronization is made. It is used for the
automatic setting of scan speed and it is an essential signal used for the
automatic recording (AUTO), manual recording (MANU), and timer program
recording.
Similar phase signal Similar phase signal appears at the same position as the phase signal in the
image signal. Depending on broadcasting stations, it may not be included in
the image signal. In JAX-9B, this signal is used for phase matching in the
manual recording and forced recording.

1.Chapter 1 General Outline of Equipment
1.1 Function
JAX-9B is capable of receiving facsimile broadcasting such as weather charts and marine charts
transmitted in the high-frequency band (2 to 25MHz) and records them on the recording paper.
1.2 Features
1.2.1 Various Recording Modes
1) Automatic recording mode (AUTO)
In the AUTO mode, all operations such as startup, various settings, image recording, paper feed,
and stop of recording are automatically performed by the remote signals from the broadcasting
station. However, the halftone recording is manually controlled.
2) Manual recording mode (MANU)
In the MANU mode, the index of cooperation (IOC), scan speed and halftone are manually
controlled, though the recording and stop are performed automatically.
3）Forced recording mode (# REC)
When the equipment is in any other mode than the mode 1) or 2) (e.g. midway during
broadcasting), received images can forcedly be recorded manually as an extension of the MANU
mode.
4）Programmed recording mode (TIMER)
JAX-9B can perform unattended operations linked with the internal timer built in its main body
by programming the program channel, start and stop times, startup mode, recording frequency
and halftone recording.
1.2.2 16-gradation Halftone Recording
Cloud photos received from a weather satellite can be recorded in 16-gradation halftone contrast.
1.2.3 Fine-line Compensation Circuit
The equipment adopts the JRC’s original system that can clearly reproduce fine lines in maps and
latitude and longitude grids.
1.2.4 Synthesizer-based Receiver Capable of Storing 90 Frequencies
Receiving frequencies can freely be preset from a ten-key pad and up to 90 frequencies (There are 10
groups and 1 group can store 9 frequencies.) can be stored in the internal memory.
In addition, the preset frequencies can be swapped with others on the spot, allowing swift response to
any new broadcast or frequency changes.

Chapter 1 General outline of Equipment
2
1.2.5 Automatic Frequency Selection
A frequency with the best receiving condition can be automatically selected among 9 frequencies in
the same group. This function can demonstrate a superior effect in timer program recording because
it is not necessary to search a frequency with a good receiving condition.
1.2.6 Internal Clock
The equipment incorporates an internal clock as a timer for programmed recording, which indicates
time.
1.2.7 Automatic Time Correction
By connecting a GPS receiver, the internal clock can be corrected automatically.
1.2.8 Displaying Received Image on PC (Option)
JAX-9B outputs received image data to a Personal Computer. The PC is able to display a received
image.
