NOTES:

• Use a serial straight through cable for connection to a

computer.

• Be sure to turn the power of both the DN-V750/V755 and the

control device off when connecting the serial cable. Failure

to do so could damage the DN-V750/V755 or the control

device.

• Do not use signals other than TXD and RXD signals (DTR, for

example). If reception control of such signals is being

performed on the control device, take the necessary

software or hardware measures on the control device.

Software specifications

These operating instructions only include a general description of the serial remote commands.

For details of the individual commands, consult your store of purchase.

2 Basic procedure for transmitting and receiving commands

Basic protocol of this interface: The device with which serial communications are possible (referred to as “the controller” below) issues

commands and the DN-V750/V755 returns messages indicating that the commands have been executed.

When using a computer, serial communications are possible using Hyper Terminal included as standard with Windows

™

95 and later.

2 Command format

ASCII character codes are used for actual commands and messages. Commands are expressed with two characters. There is no

distinction between capital and small letters, but the two must not be combined.

The <CR><LF> code (0DH,0AH) is affixed to the end of commands in the native mode. The <CR> code (0DH) is affixed to the end of

commands in the LD compatible mode. The DN-V750/V755 recognizes that the command is complete through this code.

Some commands may include parameters (arguments), but as commands also serve to terminate parameters, be sure to place

parameters before the command and do not include spaces, etc.

The maximum length of commands including arguments is 49 characters in the native mode, 32 characters in the LD compatible mode.

Example : Native mode

20SE<CR><LF> : Search for 20th clip

In this case, 20 is the parameter, SE is the command.

LD compatible mode

100SE<CR> : When the search mode is set to “Frame”, search for 100th frame.
