2.3. SX-2000AO and SX-2100AO
2.3.1. Setting the device number
Notes
• When setting the device number for multiple SX-2000AO and SX-2100AO units, assign different numbers to
each unit. The device number that can be used must not exceed the actual number of SX-2000AO and SX-
2100AO units set using the SX-2000 Setting Software.
• If a device number is duplicated, then the SX-2000AO and SX-2100AO units assigned that number cannot be
controlled by the SX-2000 system.
Step 1. Remove the protective cover on the SX-2000AO's or SX-2100AO's front panel by unscrewing it with a
Phillips screwdriver.
