WDM 8000
Wireless data modem 9600/19200 Baud with RS232 interface
Use a 25-pole D-Sub connector to connect the WDM 8000 with a power supply (8 to 16 or 18 to 60 Volts DC) and external devices. The interface has 4 additional digital or analog* in and outputs.
With the accessories set (cable and software), you can easily adjust important parameters like R232-settings, transmission and reception frequency and the transmission power output.
The numerous function- and status indicators at the front of the data modem indicate the current status of the device. Over the 25-pole interface, data can be read and processed.
Because of the robust metal housing (IP54), you can install the data modem on a DIN rail or directly onto a flat surface. You can get the data modem with the signal modulation FFSK (9600 Bd/ 19200 Bd).
