Signal Connections
The signals used in the HSR-1/1P are shown below.
Use a cross-wire (flipped) cable to connect a computer
to the HSR-1/1P. The RTS and CTS are not controlled
and are shorted in a VTR. Therefore, either set the
computer so as not to control the RTS/CTS signals or
connect wires between the pin 7 and pin 8 as shown by
the broken lines in the figure above.
Data Format
The data format is preset as shown below. Only the
baud rate can be changed.
Mode: Asynchronous
Data Length: 8 bits
Parity: None
Stop Bit: 1 bit
Baud Rate: 1200/2400/4800/9600/19200/38400
bps
Bit Structure
Note
This interface may not operate at 19200 or 38400 bps,
depending upon the specifications of the computer and
characteristics of the cable. Select a lower baud rate.
