INSTALLATION
The figures and tables in this section contain all
of the information necessary to correctly
interconnect the devices in a TASCO color SSTV
system.

VIDEO OUTPUT
The video output port provides a signal for
incoming SSTV pictures or pictures from the video
input port.
Connect a color video monitor to this
port.
A color video printer, a VCR and other
video input devices may be connected to this port.
RADIO Port
The radio port has connections to a transceiver and
a microphone including a push to talk line.
The
connection must be made according to your radio
equipment.
Refer to your radio's manual for
microphone pin assignment, or use one of MR-70
series microphone connectors. (Available for ICOM,
KENWOOD and YAESU transceivers)

INTERFACING A C O M P U T E R
TSC-70 may be controlled by a PC using either the
EB-232 or the EB/PC-70, which are available as
options.
Some of their capabilities are:
1. All the remote control functions
2. The picture data in the TSC-70 can be saved in
the special format or BMP/JPEG format.
3. The picture data in the PC can be loaded into
the memory of the TSC-70.
4. A picture can be made to be 1/4 of the original
size and placed at upper right, upper left,
lower right, lower left or center.
5. Letters can be written on the screen using
the video typewriter function.
6. Cut & paste of a picture.
EB/PC-7OP/V comes with an interfacing card for a
PC to save and load the video data at 312 Kbps.
It takes only 7 to 8 seconds to transfer the
picture data using a hard drive.
6
EB-232 does not require an installation of a
card.
It uses a serial port, RS-232, of the
computer to transfer the picture data. The
transfer rate is 115 Kbps with IBM PC/AT 's.
