Local Operation With a PC (DADS-1)

The DADS-01 can also be operated locally through its rear-panel USB interface. This requires using a PC with a USB Port and a communications program such as HyperTerminal that is supplied with the Windows XP OS. Other equivalent terminal-type programs like TeraTerm can also be used. This mode of operation is known as the VT-100 mode.

You must also have previously installed the DADS-01’s USB driver so that your PC can communicate with the DADS-01. This driver is included in the software package found on the CD supplied with the DADS-01 (see this article).

The communications parameters that must be set in your communications program (HyperTerminal or equivalent) are: 115200 baud, No parity, 8 bits, 1 stop bit, no flow control and the appropriate COM port. Also make sure that the New Line Character is set to CR+LF in your communication program. Once communications is established, press any key and the following screen will appear.

To change any of the first 15 displayed parameters, enter the corresponding line number followed by “Enter”. Next, type the desired value for that parameter followed by “Enter”. The menu then refreshes itself displaying the updated value.

Note: only positive numbers can be entered for line items 2,3,6,7,10 and 11 (without the – sign). Line items 1 and 14 toggle On or Off simply by typing the line number. Channels in alarm are shown on line 16.
