Flash Update Steps:
1. Download the FLASH file for the 2x16 from the Lightwave FTP site to
your Laptop or computer.
2. Connect the computer's serial port to the CONTROL IN port of the
PC ServerSwitch 2x16. [If the unit had been cascaded with other
units, the cascade connections must be broken. Each 2x16 unit must
be updated individually.]
3. Start the communications software. Configure the communications
parameters to 38,400 baud, 8 data bits, no parity, 1 stop bit, and DTE
(38.4K 8N1 DTE). Select the correct serial port (i.e., COM1) as the

any attached keyboard, or pressing the Scroll Lock key twice.

a message through the serial port prompting the Terminal program to

the file transfer begins, although there is no visible confirmation
through the user's computer screen that the flash update has begun.
After about two minutes, the file upload (from PC to 2x16) is
completed. If no response after 5 minutes, you must start over.
