8 SR50A Firmware Updates
The firmware on the SR50A can be updated by using a
terminal program such as Hyperterminal. If your SR50A is
configured for RS-232 communications, the SR50A can be
programmed from the I/O cable. The SR50A also contains an
internal female DB-9 connector.
Firmware updates should only be performed at an appropriate
workstation with static control procedures in place. Failure to
follow the procedures may cause damage to the sensor.
