Syntax 

devno consists of a 32-bit value comprised of the COM port number, two digits representing the device model number, and the Baud Rate (see Baud Rates).

Low byte = COM port number (01 to 16)

Note: This function does not change the COM port number of your device nor does it find the COM port number of your device. You must know the COM port number of your device to use this function with serial port products and/or USB products that use a Virtual COM Port (DI-145, DI-148, DI-149, DI-158, DI-71x USB devices).

High byte of low word = device number:

	Device	Value	Hex Value
	DI-145	45	2D
	DI-148	48	30
	DI-149	49	31
	DI-154	54	36
	DI-158	58	3A
	DI-245	46	2E
	DI-710U	71	47
	DI-715U	72	48
	DI-718U	73	49
	DI-194	94	5E
	DI-195B	90	5A

High word = The Baud Rate. Use the high word to set the Baud Rate of your instrument. Some possible values for Baud Rate are:

	Baud Rate	Hex Value	notes
	4800	12C0	power-up default for DI-145, DI-154, DI-194
	38400	9600	power-up default for DI-148, DI-149, DI-158, DI-71x
	115200	FFFF	highest possible Baud Rate for DI-71x devices; default for DI-245
	460800	FFFD	highest possible Baud Rate for DI-148 and DI-158

See a complete list of possible Baud Rates.

Example:

For a DI-158 on COM4 use:

		high word	high byte of low word	low byte
		Baud Rate	Device Number	COM port
	values	38400	58	04
	hex	9600	3A	04
	signed decimal	-1778370044

devno = A pointer to a string containing the first eight hexadecimal digits of the device serial number. For multiple devices of the same model, or when using DI36nNT.DLL, multiple DI-4208, DI-4108, or DI-1120 devices, use commas to separate their serial numbers. A null string of "00000000" opens all connected devices of the model supported by the DLL, sorted in order of increasing serial number, or for DI36nNT.DLL, sorted in order of decreasing model number, and in order of increasing serial number within each model.

devno = USB ID (0 to 15). Default is 0. The USB ID is flashed into the device from the factory (unless you specified a different ID upon purchase, the ID is 0). Contact DATAQ Instruments for information about changing the USB ID of your device.

devno = Pointer to IP address of the device.

devno = LPT port number (1 to 3)

devno = WinRT virtual device number. The WinRT virtual device # can be found in c:\Windows\tpdataq.ini, or at the end of the WinDaq installation.

devno = Device ID (0 to 15). Default is 0. The Device ID can be changed by removing jumpers labeled Device ID 1, 2, 4, or 8 on the circuit board of the instrument (must be done prior to installing the hardware).

	Device ID	Jumpers Installed
	0	ALL
	1	2,4,8
	2	1,4,8
	3	4,8
	4	1,2,8
