8 Operating the alarms
The alarm output can be used to switch an external alarm indicator. The external alarm switch is an open collector
transistor switch to ground with a maximum rating of 0.25A DC. It is possible to wire the alarm contacts of several
Stratomaster instruments in parallel should this be desired. To avoid false activation of the alarms, the alarm function is
only active 10 seconds after the instrument has powered up.
9 Firmware Upgrading
The INFO-1 can be upgraded in the field by connecting the RS232 port to a PC and running the firmware update
program. Note that only the RS232 port can be used to upgrade the firmware.
Please see the Vega firmware upgrading document for more information.
Max Values CRC error. Load default settings to restore to factory defaults. If the error
message still persists then it could possibly be a non-volatile memory failure in which
case the instrument will then have to be returned to the factory.
