Requirements
Programming the Model 405 and 211 monitors requires a computer running the "Analog
Devices Serial Downloader" program to download the firmware from the computer to the
monitor, and the
straight through
rs232 serial cable provided by 2B Technologies. The
computer must have a serial port or a USB port with a USB to Serial converter cable to
connect to the rs232 serial cable provided by 2B Technologies.
Procedure
I. Install Windows Serial Downloader Application
1. If not already installed, please install the WSD.exe application provided by 2B
Technologies.
2.
In the “Configuration” menu on the WSD, set the Port number to the COM port
that corresponds to the one your serial connector is connected to. Normally
this is COM1 unless you do not have a serial port on your computer and you are
using a serial to USB converter. If using the serial to USB converter, check in
Windows Device Manager for the correct port number corresponding to the
converter.
II. Record all stored parameters
1. Enter the main menu and write down or record calibration parameters (CF, SF,
NO2 and NO slope, NO2 and NO zero), averaging frequency. This is
imperative as you will need to re-enter these parameters after programming the
new firmware.
III. Removal of top cover
1. Remove the six screws on the tops of the sides securing the top cover on.
2. Remove the unscrewed lid.
IV. Programming instrument
1. Plug in 12V power source for instrument.
