Twisted Pair Configuration
2040 domes can be operated on 20mA current loop
twisted pair cabling by using a DRX100 card and power
supply (Dennard part num 95066). In this configuration
the switches must be set to setting 1
(see table 9)
.
This setting should also be used for alternative local
protocol converters such as the DaxDen.
Note that the DRX100 card also provides 4 local alarm
inputs. For details on connecting the alarms refer to
the DRX100 operating manual.
