Wiring
The 17-pin M23 male connector is located at the bottom of the WMT700
sensor. The connector is used for power supply, digital communications,
and analog outputs. The signals related to digital communications are
galvanically separated from the ground. The connector type is Hummel
7.106 series.
Cables
Ready-made cables are available for use with Vaisala MAWS and
AWS520 systems. These cables have connectors on both ends. There is
also a retro-fit cable for Vaisala ROSA system in case analog output has
been used with WS425.
Vaisala provides open-lead cables for connections to other host systems:
- Cable 2m (Spare part item 227567SP)
- Cable 10m (Spare part item 227568SP)
- RS485 Cable 2m (Spare part item 228259SP)
- RS485 Cable 10m (Spare part item 228260SP)
- ROSA Cable 10m for Analog Outputs (231425SP)
The first two cables carry through all signals from the WMT700 while
the RS485 cables are dedicated for RS485 operation with a limited
number of wires.
Table 8 on page 53 shows how to connect Cable 2m (227567SP) and
Cable 10m (227568SP).
Table 10 on page 55 shows how to connect RS485 Cable 2m (228259SP)
