Modem DMX501
The DMX501 communication module is used for providing long
distance fixed line connection between MAWS and another Vaisala
equipment with a similar interface, max. distance up to 10 km..
Through this I/O port, MAWS can send reports and data or the host
can poll them.
The DMX501 modem module supports the following communication
standards:
- V.21, 300 bps FSK
- V.23, 1200 / 75 bps FSK
- V.22, 1200 bps DPSK
The DMX501 modem module must be configured before using it so
that it works as desired. The Lizard Setup Software is used for this
purpose.
