How do i read an I/O register using SNMP ?

All registers in the Barionet which hold I/O values can be read and written via SNMP. You can easily control the relays, for example, by using SNMP set requests on registers 1 and 2.

The detailed register map is documented in the Barionet manual.

How do the registers map to Object ID's ?

This is defined in the Barionet MIB, which is included in the device (you can access it with the URL /barionet.mib on the device), and on the Barix website. Here is, for example, the OID for register 201 (digital input 1):

1.3.6.1.4.1.17491.1.1.2.1.2.201.0

Note the .0 at the end - and the number before is the register.
