8.1 Software 
Updating
The Model 250 software resides in Flash Memory and is updated via the
projector's serial Port A. To perform an update, a disk containing the updated
Boot Software (boot.hex) and/or System Software (zsys.hex) and a PC with
Windows 3.1 (Windows 95/98 with Procomm Plus fax/modem software) is
required to perform update.
Boot Manager Software and System Software are separate products. Each may be
updated independently. The System Software will depend on a specific version of
the Boot Manager. Refer to the System Software release bulletin for Boot
Manager version dependencies.
To perform software upgrade:
1.
 
Verify that the projector circuit breaker is off. Use a Null Modem cable to
connect a PC to the projector’s Serial Port A (Terminal-In).
