Warranty and Repair Section 9
9.1 SOFTWARE UPGRADE PROCEDURE
If necessary, the YSI Model 3200’s software can be upgraded using a computer with a serial port.
All that is needed is any standard communications software, new 3200 software and a straight
RS232 serial cable (not a null modem cable). The 3200 has a female DB-9 connector. A 9 to 25
pin adapter will also be needed if the computer has a 25 pin serial port. The instructions are as
follows:
1. Connect the 3200 to your computer serial port using a straight RS232 cable.
2. Insert the software update disk into the appropriate drive (usually A: or B:).
3. Start your communications program (such as ProComm
TM or Windows TM terminal).
4. Set your communications parameters (in the communications software on the
computer) to the following:
Baud Rate: 9600
Data Length: 8 bits
Parity:
None
Stop Bits: 1
NOTE: Make sure the COM port matches the one that the 3200 is connected to.
5. Turn the 3200 on and quickly press [ESC] on the computer keyboard.
The 3200 screen should go blank, the computer screen should display:
“Press (ESC) to cancel application”
"3200 Bootware ver 1.1"
"$"
6. On the computer keyboard, type "LOAD" then press [ENTER].
The computer screen should display:
“MFG = 0089 Device = 4470”
"Erase ROM(Yes/No/Abort)?"
7. On the computer keyboard, type "Y".
After 2 or 3 seconds, the computer screen should display "Load File:"
8. Enter your communications program command to “Upload File” (such as the PageUp
key in ProComm TM or "Send text file" in Windows TM terminal. If you are prompted
for a protocol, select “ASCII”.
9. When prompted for the file name, enter “A:3200A1.HEX” or “B: 3200A1.HEX”
(depending on the drive you placed the disk in). NOTE: The file name may vary.
Letters/numbers (hex) should count up on the computer screen and it may display:
“SENDING: M3200A1.HEX”
After the file is finished (a few minutes), the computer will beep and the $ sign will
appear on the screen again.
1. Unplug the 3200’s power plug and RS 232 cable. After 5 seconds, reconnect the
power plug and turn the instrument on for normal operation.
NOTE: If anything goes wrong (garbage all over the computer screen), turn off the 3200
(by unplugging the power supply from the back of the instrument) and start again.
