Safety Puck Firmware Update Process

Note: You must know your WAM's type before beginning this process. See WAMTypes to determine your system's type.

Step 0: Determine Correct Firmware Version for Your Safety Puck

Refer to the following table to find the correct version:

WAM Version	Firmware File
WAM-OA	​puck2.out.r39b.noenet.opt
WAM-O[B|D|E]	​puck2.out.r39b.enet.opt
WAM-MA	​puck2.out.r102.noenet.mag
WAM-MB	​puck2.out.r102.enet.mag
WAM-MD	​puck2.out.r119.enet.mag
WAM-ME	​puck2.out.r197.enet.mag
WAM-H	​puck2.out.r102.enet.mag

Use btutil to determine the current firmware version on your safety puck. If it is already the correct version, there is no need to continue with these instructions.

Step 1: Connect to the Safety Puck over Serial

If your system matches type WAM-xA, connect the ​serial cable inline with the ​serial download adapter to the safety board. See ​this picture for reference.

If your system matches type WAM-xB, connect the ​serial cable to the connector near the safety puck and ​flip the nearby switch to the "ON" position (away from the puck).

If your system matches type WAM-xD, wait for further instructions.

If your system matches type WAM-xE, connect the ​serial cable to the connector near the safety puck and ​flip the nearby switch to the "ON" position (toward the puck).

Step 2: Set Up the Computer

Connect the other side of the serial cable to COM1 of a Windows PC.

Turn on main power to the WAM

Download ​F28xxConsole.exe

Step 3: Flash the Firmware

Under MS Windows, quit any programs that may be using the COM1 serial port. Simultaneously drag ​puck2mon.out.r9.c20 and your correct firmware file (from above) onto F28xxConsole.exe

NOTE: Some Safety Boards with older pucks may require the 32MHz version of monitor: ​puck2mon.out.r9.c32

Wait for the download to complete (about 4 minutes)

Turn off main power to the WAM

Step 4: Replace the Serial Cable

If your system matches type WAM-xA, For Type A: Remove the serial download adapter- connect the serial cable ​directly to the safety board

If your system matches type WAM-xB, ​Flip the nearby switch to the "OFF" position (towards the puck).

If your system matches type WAM-xD, wait for further instructions.

If your system matches type WAM-xE, ​flip the nearby switch to the "OFF" position (away from the puck).

Set Safety Firmware Defaults

Launch TeraTerm/Hyperterminal (9600 baud, no parity, 8 bits, 1 stop bit, no flow control)

Turn on main power to the WAM. You should get a prompt (=>). Type the following commands in sequence, each followed by <Enter>. A mis-typed command will NOT result in an error message, so type carefully! Note that this assumes you are using a verified 48.0 VDC power supply. Following these instructions with a different supply could damage your WAM, please contact us for custom instructions in this case.
