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:
o
1 PC running HyperTerminal (or other terminal program) equipped with a 9 pin or 25 pin serial port
o A VEEMUX made to use the Firmware Upgrade feature
o 1 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)
o A 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.
