Connection to a PC via a Power and Communications Interface WindMaster (1590-PK-020/W
+options, WindMaster RA (1590-PK-130/W) +options and WindMaster Pro (1561-PK-020/W +
options).
Dependent upon system requirements the WindMaster unit can be operated with the Power and Communications and
Interface unit (PCI), which can be ordered as an optional extra. Connect WindMaster via RS422 port; then connect
computer to RS232 port on PCI.

Environmental
The Desktop PCI is intended for use in a protected environment and provides interfacing to a single anemometer.
RS232 and RS422 ports are provided. The PCI is not intended for outdoor use.
PCI Electrical Power Requirements
1)
100Vac - 120Vac, 10VA from a mains supply for the 115V switch position.
2)
200Vac - 250Vac, 10VA from a mains supply for the 230V switch position.
3)
9 - 30Vdc, 55mA from an external low voltage supply for the anemometer (excluding analogue outputs).
4)
8 - 15Vdc, 50mA max from an external low voltage supply for the interface box only.
3 fuses protect the unit:
1.
Externally accessible
1 A (T) for 115/230v operation.
2.
Internally accessible
500 mA (T) AUX.
3.
Internally accessible
500 mA (T) ANEM.
PCI Operation.
There are three Red LED’s on the PCI front panel.
When the PCI box is powered the Power LED will illuminate.
When a WindMaster/WindMaster Pro is connected as above to the PCI box and is set to output continuous data the PCI
box RX LED will flash on/off at the WindMaster output rate thus giving a good indication that the WindMaster output
is wired to the PCI box correctly and outputting RS422 data correctly.
If the PCI RS 232 connection is connected to a computer then when a terminal programme is opened and commands
sent by a PC keypad or program to the PCI box its TX LED will illuminate intermittently indicating a good connection
between the PC and PCI box.
