Character Search (continued)

♦Sample operation

1)Record characters “ABCDEF” and images simultaneously at the camera CH number 5. (On the RS-232C settings screen, set DELIMITER to “CR”.)

The following are the two steps required for recording characters:

1Set the character (or characters string) to be recorded;

2 Record the selected character(s).

By using the CM command, characters which have been set once can be recorded any number of times. To record a different character set, use the CW command.

Command from personal computer	Replied status code from unit		Meaning
	to a personal computer
CW06,ABCDEF CR			Sending a command for setting "ABCDEF" .
	RC CR	EX CR	The unit received a command and executed.
CM05 CR			Sending a command to record set characters at the camera
			CH number 5 (it is able to execute while recording).
	RC CR	EX CR	The unit executed a command.

CR

means a carriage return code (0DH).

•Set the CH. TITLE setting to “NONE” to display characters during segmented display mode.

2)Search for the scene associated with the recorded character set “ABCDEF”. (On the RS-232C settings screen, set DELIMITER to “CR”.)

Command from personal computer	Replied status code from unit		Meaning
	to a personal computer
CR1 CR			Display characters on-screen (Playback only).
	RC CR	EX CR	The unit received a command and executed.
LF06,ABCDEF CR			Sending a command for serching "ABCDEF" by character
			search in a direction of the time being.
	RC CR	EX4 CR	The unit received a command and executed.

CR

means a carriage return code (0DH).

3)Search for the scene associated with the recorded character set “ABCDEFG”. (On the RS-232C settings screen, set DELIMITER to “CR”.)

By using abridged search by ✽ code, search can be made using only a specified number of characters found at the head of recorded characters.

For the recorded characters “ABCDEFG” ,searches can be made using any of the following patterns specified for number of character data.

Example of commands : LF02,A ✽ / LF03,AB ✽ / LF04,ABC ✽ / LF05,ABCD ✽ / LF06,ABCDE ✽ / LF07,ABCDEF ✽

Command from personal computer	Replied status code from unit		Meaning
	to a personal computer
CR1 CR			Display characters on-screen (Playback only).
	RC CR	EX CR	The unit received a command and executed.
LF04,ABC ✽ CR			Sending a command for serching "ABC ✽" by abridged
			search by ✽ code in a direction of the time being.
	RC CR	EX4 CR	The unit received a command and executed.

CR

means a carriage return code (0DH).

•Character searches can only be performed during stop, pause, and playback modes.

•The unit will fast forward or rewind until it finds the character string, then shift into still frame mode.

•If the unit does not find the character string, it will stop automatically.

•When there are multiple instances of the same character string, repeat character search if the retrieved image is not the desired image.

•Character searches may be time-consuming as the process involves searching through all the data.

•Forward searching is the only option available when using a DDS device for playback.
