4.1.2 MAX15500 Output Conditioners

Following USB connection, the MAX15500 Output Conditioners section will refresh to show the default

configuration and initial error states of the MAX1550 devices. Upon any power-up (or supply brownout

condition), the Supply Brownout alarm is expected. A red LED on the MAXREFDES24 hardware will also be

on. A subsequent Refresh of the MAX15500 Output Conditioners section will clear the alarm.

One can set the Brownout threshold in 2V increments from ±10V to ±24V. In the MAXREFDES24 design, a

brownout threshold of ±24V triggers a Supply Brownout alarm.

The default mode upon power up for the analog outputs is Standby with a ±10V brownout threshold and

thermal protection disabled. Use the Configuration sections to configure the on-board MAX15500 signal

conditioners to output common industrial control signal ranges (current or voltage) and to read back any error

conditions the MAX15500 report.

• Use the Refresh button to read and refresh the Configuration and Error(s) status of the MAX15500

devices.

• Use the Apply button to write the displayed configuration to the MAX15500 devices. Enable Refresh

On Apply to immediately issue a read or Refresh command following a write or Apply.
