RS232 UPGRADE OF THE FRONT PANEL LCD FIRMWARE

The firmware in the front panel LCD can be upgraded to include the latest features available using either the RS232 port (below) or Ethernet Control (page 19). Follow the procedure below to use the RS232 method to update the Front Panel LCD firmware in the VEEMUX. To prepare, first download the rmtlcd_va_1_x. hex file (x= the current firmware version) from the NTI Video Matrix Switch website http://www.networktechinc.com/vmtx.html.

The following will be needed:

o1 PC running HyperTerminal (or other terminal program) equipped with a 9 pin or 25 pin serial port

oA VEEMUX made to use the Firmware Upgrade feature

o1 serial cable wired straight through to connect your PC's serial port to the “RS232” port on the VEEMUX (see cable specifications on page 31)

oA firmware file for a VEEMUX downloaded from www.networktechinc.com

Procedure:

1.Power OFF the VEEMUX.

2.Connect the null modem cable between the serial port on the PC and the “RS232” port on the VEEMUX.

3.Use HyperTerminal to prepare to connect to the VEEMUX (using settings 9600 baud, 8-N-1 no flow). Make sure HyperTerminal has been configured for connection through the correct COM port on the PC.

4.With the HyperTerminal window open, hold the spacebar and apply power to the VEEMUX. A command menu and the Command prompt (>) should appear.

Flash Loader Utility v1.0

HDisplay this help menu C Clear flash

L Load flash with .hex file

Command>

Note: Commands are not case-sensitive (for example, 'h' or 'H' will execute the help command), and the <Enter> key is not required to execute a command.

If the Flash Loader Utility menu does not appear, the VEEMUX you have may have been made prior to the release of this product change. To verify this, with the VEEMUX powered ON, at the HyperTerminal window enter the following command:

RV 01 (be sure to include the space)

The following revision string will appear:

$date: 2006/04/17 20:20:59 $$revision: 1.1 $$IN: 08 $$OUT: 04 $

If the date shown is before 2006/04/17, then the VEEMUX firmware cannot be upgraded using this procedure.
