4181 Firmware Update v. 1.14

Title:                 4181 Ver 1.14 Update
Ver:                   1.14/1.14
Use with:          4181
Date Modified: 03/07/2013

Description of the change: 
Firmware updated to fix a bug found in the SetPt menu screen when operating the F4 disable key in release Vers 1.13/1.14.

Firmware updated in the main (Primary) processor to fix the Maximum Setpoint in the 4181. The Maximum Setpoint is reduced as a result of an increased emissivity.  Reduction results with Emissivity between 0.95 and 1.0, Max Setpoint is restricted to 500°C down linearly to 483°C respectively.
The Serial communications also updated to reflect this change.

Changed the unit operation to use the Emissivity from the active program when operating a program.  Limits Temperature based on the active Programs Emissivity.

Changed control approach (4181 only) to allow more time for system to react.
At 300°C the system would oscillate due to Fan switching between low and High speed.

Recalibration of unit is not required with this update.

Download Requirements:          
Locate a computer with an available RS-232 COM port, with Windows XP or newer operating system.

Locate an RS-232 Null modem cable and connect one end of the cable to the instrument, the other end to the RS-232 serial port on the computer. 

Note: If your computer only has USB serial interface, an adapter from USB to RS-232 will be required. Recommended adapter: Keyspan USA-19HS.

Instructions:

Copy the Code Transfer Software to a convenient directory on the computer. There are four files included in the folder (these include one installation instruction, two .bin files and one .exe to install the program in your unit.  The number in the name of the .bin files must match the model of the instrument to be programmed.

Unzip the files, and read the download instructions.

Run the Code418x.exe (FW download utility).  The software will allow you to select the available
COM port.

The New firmware will be transferred to the instrument through the RS-232 cable.  The status of the transfer will be shown on the instrument and on the computer screen.  When complete the computer screen will show “Code Transfer Successful” and the instrument will restart.

If the code transfer fails try it again, but first force the instrument to code transfer mode by pressing the “Enter” and “Exit” buttons at the same time.

If the incorrect language set is downloaded, reload the correct language set.

Having successfully updated the embedded firmware check to make sure all calibration parameters are correct before making measurements with the instrument.  Calibration parameters can be found on the calibration report for the instrument.
