The Plus-X VSWR is now ready for operation in your system as either a stand-alone device or as
part of an Arcturus or ARC Plus comprehensive monitoring and control system. Repeat this
process for each Plus-X VSWR you install in your monitoring and remote-control system.
METER INPUT WIRING
The Plus-X VSWR can provide forward and reflected power measurements and VSWR calculation on up to
four transmission lines simultaneously. For each transmission line, two RF power sensors provide an analog
voltage signal to the inputs of the Plus-X VSWR. The metering inputs on the Plus-X VSWR only accept inputs
between 0 VDC and +10 VDC. An appropriate calibration factor is required for each input. Metering input
pins are pre-assigned to transmission line inputs and cannot be changed. See Table 5.
