3-30 Advanced Programming
Loading New Software At some point, a new version of the MIS-1 operating software may be
released or your existing software file may become corrupted. To
update your own system, use the following guidelines:
1. Record all of the setup, configuration, calibration and reference
information from the MIS-1, and transfer required logs to a PC.
IMPORTANT: All of the settings will be lost when the code is
updated. Any logs will also be erased.
2. Obtain the new software file (with a *.cod extension) and save the
file to your PC hard drive.
3. Set up the MIS-1 with an RS232 cable connected to a COM port
(most likely COM1) on a PC having a communications program
like Hyperterminal. (See Setting Up the RS232 Communications
Port in Chapter 3 of this manual, and Connecting a PC or Printer
in Chapter 1 of the Service Manual.)
4. Start the communications program on the PC and select the COM
port with the connection to the MIS-1.
5. Set the following information:
Baud Rate = 19200
Data Bits = 8
Parity = none
Stop Bits = 1
Flow Control = none.
6. Turn on the power to the MIS-1.
7. Press and hold the 0 key.
Note: The display will indicate a message similar to
Reload Flash
via RS232 (Y/N)?
8. Press the YES key.
9. Choose the Transfer file menu and select Send File.
10. Select the XMODEM transfer protocol.
11. Select the file to send: the file that was saved to the PC hard drive.
The meter will reboot and load the new software.
Note: Once the software is loaded into the MIS-1, it will be
necessary to reprogram the configuration data, references,
recorders, alarms, logs, etc (see the previous sections in this
manual).
After the reprogramming is complete, the MIS-1 is ready for
operation.
