Status Output

The status output is available for use by your application. The signal connections are

optically isolated. You can use the status output in one of two ways.

• Attach the STSOP and STSOR pins to an optically isolated device.

• Attach STSOP to PWR and STSOR to GND, and use STSO as a TTL output (the

current-limiting resistors on PWR and GND protect the MVS-8100C and the host

computer).
