called a COM port).
Note:
If the computer is to be mated to the
Pachette 2
for extended periods of
time, it is recommended that the “D-Type” connectors be secured to the computer
and the
Pachette 2
by using the (2) screws on each connector.
5. Turn on the
Pachette 2
power switch and the computer power switch.
Transferring Pachymetry Data To A Computer
As explained above, DGH Technology, Inc. does not provide software for a personal
computer that will accept a data transfer from the
Pachette 2
. However, no matter
what software is developed by the operator or a third party, the following general
guidelines can be used when transferring pachymetry data to a personal computer.
1. Start an appropriate computer software program that is capable of communicating
with the
Pachette 2
through the designated COM port.
2. Adjust the computer COM port settings to the following: parity = none, data bits
= 8, stop bits = 1, baud rate = 9600.
3. Obtain pachymetry measurements as described in section VI.
4. Start the data transfer by pressing the
DATA XFER
key on the
Pachette 2
front
panel.
Note:
If no data transfer occurs and the display indicates “NO
INTERFACE
DETECTED”, check the data cable to make sure that it is properly mated.
5. After the data transfer is completed, the
Pachette 2
will retain a copy of all
measurements in memory. The operator can either initiate another data transfer or
press the
CLEAR
key to erase all measurements and begin a new measurement
session.
