Page 13: Chapter 2 Product Overview
WAC155 The Vaisala Serial Wind Transmitter WAC155 converts the digital data supplied by the Vaisala 151 and 252 Series wind sensors for use in the RS-485 bus. The WAC155 transmitter consists of a component board in a junction box and a cross arm for mounting the wind sensors; see... -
Page 14: Figure 1 Vaisala Serial Wind Transmitter Wac155
User's Guide ______________________________________________________________________ The main features of the WAC155 are as follows: Communication with NMEA 0183 compliant protocol over RS-485 electrical interface (half-duplex) Capable of measuring the wind parameters at a configurable interval using the instant method according to the WMO standard... -
Page 15: Chapter 3 Installation
Additional protection is needed in regions with frequent, severe thunderstorms, especially when long line cables (> 30m) are used. Vaisala recommends using a surge protector such as the WSP150 in all sites where there is an elevated risk of lightning strike. -
Page 16: Figure 2 Recommended Mast Location In Open Area
User's Guide ______________________________________________________________________ 0204-040 Figure 2 Recommended Mast Location in Open Area In general, any object of height (h) will not remarkably disturb wind measurement at a minimum distance of 10 h. There should be at least 150 m open area in all directions from the mast. Refer to Figure 2 on page 14 ___________________________________________________________________M210822EN-A... -
Page 17: Installation Procedure
(H), the minimum length of the mast is 1.5 W. Installation Procedure For installation, follow the procedure below and refer to corresponding sections for details. Remove the four screws holding the cover of the WAC155 transmitter. Remove the cover. Select the RS-485 termination according to the instructions in section Jumper Settings on page Enter the power and signal cables through the cable glands(s). -
Page 18: Jumper Settings
Termination is implemented by a 120 resistor on the component board. In a simple point-to-point configuration where only one WAC155 transmitter is used the jumper is always in ON position. In a multidrop configuration where several WAC155 transmitters share the single RS-485 communication line, the termination jumper is in ON position only at the physically farthest transmitter (i.e. -

User's Guide ______________________________________________________________________ 0702-008 Figure 7 I/O Connectors The following numbers refer to Figure 7 on page X1 = Plug-in connector with screw terminals (5 pcs) for the anemometer cable. Maximum wire cross section area is 1.5 X2 = Plug-in connector with screw terminals (8 pcs) for the power and signal cable. -
Page 21: Sensor Wiring
The transmitter connects to the wind sensors with the cross-arm's standard cables through two cable glands. Through these cables the WAC155 transmitter both feeds the sensor power and receives the wind data. Plug-in type screw terminal connectors are provided both for the sensor cables and the output line cable. -
Page 22: Signal Output
Glands for power and signal cables Wind vane cable Signal Output The WAC155 transmitter provides a half-duplex RS-485 serial bus connection. Wind data is provided in standard NMEA messages. In addition, a service connection is available for configuration and status information. -
Page 23: Powering
0-9. Typically, only a 4-wire shielded cable is required for the line between the WAC155 transmitter and the receiving end. Two of the four wires provide the operating power for the system. A twisted pair can be used for the power wires to reduce interference. -
Page 24: Optional Heating Power
User's Guide ______________________________________________________________________ Optional Heating Power The WAC155 transmitter also provides the sensors with a throughput for heating power, which can be connected if sensor heating is required. The heating power is galvanically isolated from the operating power. The heating power connection requires an extra pair of wires. Since the... -
