HSR-1/1P
1999 by Sony Corporation
Purpose of This Manual
This manual describes the procedure for controling the HSR-1/1P Digital
Surveillance Recorder using the RS-232C from an external computer, etc.
The RS-232C is the EIA standard for the interface of the communication via a
modem between data terminal equipment. In this interface, data are transferred
serially bit by bit. Since the RS-232C interface is employed in most computers
as a standard interface, it can be used in a wide range of applications.

RS-232C interface
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.

CMD PARAM. PARAM.
RET RET RET
Communication is carried out in units of bytes in the
following procedure. When the computer sends one
byte of data, it waits for a return from the VTR before
sending the next byte. The return from the VTR may
not only be one byte of data, but can be multiple bytes
of data. For a command, such as EJECT, which takes
time to execute, not only the return immediately after
receipt of the command is issued, but a return
indicating the result of execution upon completion of
operation is also issued. The command, the return
from the VTR, and parameters are all defined as the
command in the RS-232C protocol.

There are three kinds of return from the VTR:
COMPLETION, NOT TARGET, and CASSETTE

execution is correctly completed.
NOT TARGET: Returned when the target point
specified by the command cannot be found.
CASSETTE OUT: Returned when the cassette is
ejected.

There are three kinds of returns from the VTR: ACK,
NAK, and ERROR.
ACK: Returned when data is correctly returned.
NAK: Returned when communication error is
detected or an unidentified command is received.
ERROR: Returned when a command cannot be
executed because of tape slack and other errors.

Notes
•Do not send the next command before receiving the
return from the VTR.
If the return from the VTR is not received within 10
msec or more after the transmission is completed,
appropriate processing must be executed because the
communication is judged not executed correctly.
•Do not send any other command between the
extended command and the secondary command.

Detailed Descriptions of Commands
VTR Return Commands
When the VTR receives a command from the
computer, it returns a VTR return command. The
HSR-1/1P supports the following commands.
ACK (0AH)
ACK is returned when the VTR receives the defined
command correctly. When the command from
computer requests STATUS SENSE or other data,
ACK is not returned, but only data is returned.
NAK (0BH)
NAK is returned if a command which is not defined
for the current mode (for example, a numerical value
command in a mode other than the numerical input
mode) is received, or when a communication error is
detected.
COMPLETION (01H)
COMPLETION is returned when the VTR has
completed the operation of the T/D SEARCH or
ALARM SEARCH command. The COMPLETION
command will not be returned if the VTR receives a
tape-run-related command or the C.L. command
before completion of the above commands, because
the VTR stops executing the above commands to
execute a new command.
NOT TARGET (05H)
Notifies that the VTR could not find the specified
position on the tape when executing the T/D SEARCH
or ALARM SEARCH command.
CASSETTE OUT (03H)
Notifies that the cassette was ejected.
ALARM IN (06H)
Notifies of alarm input. Each time an alarm is
generated, this command is issued. Which channel is
in alarm status can be confirmed by using the ALARM
SENSE (DAH+C4H) command.
Numerical Value Commands
The numerical value commands are used to specify
numerical parameters. These commands are also used
when returning numerical data, such as time data, from
the VTR to the computer. The following four
command formats are supported:
Numerical value commands 0 to 9 (30H to
39H)
To express numerical values 0 to 9 for each command.
ERROR (02H)
Notifies of generation of an error during operation.
ERROR is returned when a VTR receives a command
that cannot be executed because of an error, such as
tape slack, etc., or when an error has occurred during
execution of the T/D SEARCH or ALARM SEARCH
command, and stopped the operation. Remove the
cause of the error and release the error status using the
C.E. and C.L. commands.
Numerical value commands A to F (3AH to
3FH)
To express numerical values A to F for each command.
Sign (+) command (A1H) and sign (–)
command (A2H)
Used to specify the sign of numerical data.
ENTER (40H)
Used to specify completion of numerical parameter
input.

Detailed Descriptions of Commands
General Purpose Control
Commands
C.E. (41H)
This clears the error status or the last character of
numerical data entered. A sign entered cannot be
cleared with this command. To clear a sign, enter the
new sign.
C.L. (56H)
This releases the error status and clears the present
command. If the C.L. command is sent after issuing a
command with numerical parameter but before
confirming the numerical parameter, the numerical
parameter input is stopped, and the command with
numerical value parameter is cleared.
EXP-1 (D8H), EXP-3 (DAH)
EXP-1 and EXP-3 are the first and third extended
commands. These commands become valid after they
are combined with a secondary command. If any other
command is issued between this command and the
secondary command, the extended command is
canceled, and NAK is returned.
Example: When the LOCK ON command is correctly
executed.

REC REQUEST (FAH)
This command must be issued immediately before
sending the REC command.
SCREEN DIVIDE (DAH+90H)
Selects the display structure.
Two bytes for the number of divisions, another 2 bytes
for the page number, and the ENTER command (40H)
must follow.
Example: To select the second page of 4-division
mode:

SCREEN AUTO CHANGE (DAH+91H)

Parameter bytes to specify the output port (A or B) and
the cycle in seconds and the ENTER command (40H)
must follow.
If 00 is specified for the cycle, no automatic switching
is executed.
If the output port is not specified, output port A is
selected.
