SERIAL (RS232C) Communication Protocol
With the SERIAL (RS232C) interface, you can control functions of this unit by transferring the specified commands from a per-
sonal computer (PC) to this unit.
Notes:
•This unit does not support the communication converted between the SERIAL (RS232C) and USB interface.
•When controlling the unit with the SERIAL (RS232C) interface, the following parameters should be identical between the
communication devices.
The setting is available in SETUP MENU – Comm –  SERIAL (RS232C) Setting.

Stop Bit
Command Format
The following pages detail how to write the commands.
1. The following details how to write the commands
STX:This shows the data start. STX (ASCII code: 02h) is always prefixed to data. h shows hexadecimal digit.
Transmission command:A command shown in the Command List is designated.
ETX:This shows the data end. ETX (ASCII code: 03h) is always prefixed to data.
The character code is ASCII.
When a command needs a parameter, a colon (:) is used for dividing the command and parameter. The following shows
how to write the commands when two or more commands are specified.
2. Response Command (from the Unit to the PC)
The unit sends back the response command for the transmission command from the PC.
•When the reception was completed successfully
The response command differs between when an ANSWER command (sending back the status or data) is required or
when not required.
•When no ANSWER command is required
The unit sends back the same identifier as that in the transmission command, as shown in the figure.

							142
•When an ANSWER command is required
The unit sends back the status or data, as shown in the figure.
•About ACK code
After receiving a command from the PC, the unit sends back the ACK code to the PC in 20 ms or less.
[ACK] = Reception succeeded (ASCII code: 06H)
After the ACK code has been sent back and the command processing has been completed, the unit sends back the
response command to the PC.
Example:
These are examples for the following operations.
1. Login with the user name of ADMIN and with password of 12345.
2. Display images from camera channel 1 on monitor 2.
3. Start playback from the point of January 1 2003, 3:00 p.m.
4. Logout

•Parameter error
When the unit cannot properly process the received command, the unit sends back an error code to the PC. After clearing
the receive buffer, the unit enters the wait state until receiving the following [STX] command.
•If the unit receives another command during the response, the unit will respond to the command after processing the cur-
rent response. 
•If the unit received the [STX] command again before receiving the [ETX] command, the unit will clear the internal buffer.
Then, the unit will process the data following to the [STX] command. (The commands received before the second [STX]
command will be canceled.)
•The internal buffer will be cleared when it fills up.*
Reason for the error
001: Command invalid (There is no associated command.)
002: Parameter invalid (The number, digit, or range of the command 
parameters is incorrect.)
003: Command invalid (The unit does not support the operation mode.)
E: Command error (ASCII code: 45H)
ERN[ETX] =Error
(9) (PC -> This unit) Logout.
[STX]AD001;OLO [ETX]
When receiving the command above, the user logged in via SERIAL (RS232C) (ADMIN) will log out.
(
10) (This unit - > PC) Response against (9).
[STX]AD001;OLO[ETX]
Note: The character code of [STX], [ETX] and [SP] are as follows.
[STX]: 02h
[ETX]: 03h
[SP] (space): 20h
3. Reception Error
The response command differs between the reception error and parameter error.
•Communication error (Reception error)
When the unit cannot properly receive the command due to the communication error, the unit immediately sends back the
NACK code to the PC. After clearing the receive buffer, the unit enters the wait state until receiving the following [STX]
command.
[NCK]     = Reception failed (ASCII code: 15H)
Reason for the communication error
1: Parity error (ASCII code: 31H)
2: Framing error (ASCII code: 33H)
3: Overrun error (ASCII code: 34H)
