There’s an important new maintenance procedure required for Stryker mechanics. When followed correctly, it allows you to use the RS485 PCMCIA card to conduct intrusive diagnostics of the chassis electronic systems through the maintenance support device (MSD).

National Instrument software version 1.5 for the RS485 PCMCIA card locks up the MSD. That was fixed with version 1.6. Unfortunately, loading version 1.6 changes the hardware configuration (com ports) on the MSD from the required 2-wire setting to 4-wire.

1. Right click on My Computer.

2. Select Manage.

3. Click on Device Manager.

4. Double-click Ports (Com & LPT).

5. Double-click NI PCMCIA-485 port 1 (com 5). Depending on the card it may have a -2 after the 485.

6. Click on the Port Settings tab at the top of the window.

7. Click on the Advanced button. The Transceiver Mode should be 2 Wire TxRdy Auto. If it’s not, click on the drop down menu and change it.

8. Repeat steps 5-7 for NI PCMCIAL-485 port 2 (com 6).

OK! VERSION 1.6 IS NOW LOADED!

YEAH, BUT NOW YOU’VE GOTTA RESET MY COM PORTS!
