UHF Radio Modem

When using UHF Radio Modem SATELLINE 3AS, the DSU232

Communication Module should be used to provide an additional RS-

232 output for the radio modem, leaving the standard COM port

(COM0) free for maintenance purposes.

For powering of the radio modem, you need a mains (AC) power supply

or a mains/solar power supply with the backup batteries. The standard

solar panel can not supply sufficient power for the radio modem. In

addition, you have to change the wiring to be able to use the MOD1 port

and the provided cable for powering the radio modem from the

External DC (+ExtDC) of the logger.

Follow the procedure below to wire the radio modem

SATELLINE 3AS with MAWS:

1. Remove the logger's cover and install the DSU232 communication

module to the MOD1 location.

2. Reassemble the logger's cover.

3. Disconnect the wires Red and Brown from the MOD1 connector

(number 2 in Figure 161 on page 218). Connect the Red wire to

GND and the Brown wire to +ExtDC terminal of the Power

connector (1).
