NOTES:
• Use a serial straight through cable for connection to a computer.
• Be sure to turn the power of both the DN-V1700 and the control device off when connecting the serial cable and switching
between RS232C and RS422A. Failure to do so could damage the DN-V1700 or the control device.
Be sure to switch to the proper RS232C or RS422A setting for the communications hardware specifications of the control device.
• Signals other than TXD and RXD (DTR signals, for example) cannot be used on the DN-V1700. If reception control of such signals
is being performed on the control device, take the necessary software or hardware measures on the control device.
