LI-3000A Portable Area Meter

The LI-3000A is configured as a DCE device. Most computers can be connected to the LI-3000A using the 1000-04 printer cable and a female-to-female gender changer. To send files from the LI-3000A to a computer, use the following functions:

1.Press the MENU key to access the functions needed to transfer data. In the list of menu items are SET I/O and PRINT FILES.

2.Set the I/O parameters as follows: BAUD = 4800

DATA BITS = 8 STOP BITS = 2

PARITY = NONE

CHECK DTR = N (not used) XON/XOFF = N (not used) CHECK RTS = N (not used)

3.Press Enter at the PRINT FILES function. Enter the range of files to be transmitted out the RS-232C port.

LI-1600 Steady State Porometer

The LI-1600 is configured as a DTE device. To send data from the LI-1600 to a computer, follow these steps:

1.Your LI-1600 must support RS-232C communications (serial numbers SSP-275 or above).

2.Connect the cable included with the LI-1600 (2230S) to the 9-pin port on the LI-1600 console. The 2230S plugs directly into any DTE equipment.

3.Data are transferred when the HOLD switch on the LI-1600 Sensor Head is toggled.
