Usually drivers are installed automatically to the computer if it is running Windows 10 (non-upgraded
version). The A035 registers itself as a virtual serial com port. A new COM port will automatically show
up in the device manager after the A035 has been plugged in.
After the driver has been installed, run device manager, and
check the
COM number
(this is the number associated with
the USB port being used. The port number is the number that
Windows assigns as an input device. These can be generated
randomly by the computer). The chart software may require
the COM number in order to access the data.
The port number for the A035 can be found in Windows
‘control panel->system->device manager’ under ‘ports (COM &
LPT)’. Find the A035 in the list for the USB variant. To change
this number, double click the A035
and select the ‘port
s
ettings’ tab. Click the ‘advanced’ button and change the port
number to the one required.
Checking the USB data flow:
If desired, the USB data can
always be checked with a terminal monitor application, like
Putty or HyperTerminal. To do this, enter the following into the
COM port settings:
Bits per second: 38400bps
,
Data bits: 8
,
Parity: None
, and
Stop bits: 1
as shown below.
Using HyperTerminal on Windows as an example
4.1.2. Mac:
For Mac OS X, the A035 will be recognized and shown as a USB modem. The ID can be checked with
the following steps:
1. Plug the A035 into a USB port and launch Terminal.app.
