Wavecom W61PC V7.5.0 - Manual (Page 20)

10  Setup WAVECOM Decoder W61PC/LAN Manual V7.5
IF70#4 52.5 MHz-87.5 MHz
IF input for SAT monitoring
50 mVrms - 5 Vrms
Input impedance: 50 Ohm
EXT-DEM Max. 12 kbps
External Demodulator Input
[0 V, +5 V] to [-12 V, +12 V]
DIG Max. 36 Mbps, Direct Input for DSP
receivers (not yet supported)
-0.5 to +6.5 V
One or more of these inputs must be connected to the signal source(s) using a coaxial cable or a similar
shielded cable. As an example a HF receiver may be connected to an AFIF connector and a satellite receiv-
er to the IF70#4 connector.
To avoid distortion of the input signal the input voltage ranges listed above should be observed.
20 dB attenuation jumpers are located on the PCB close to the corresponding input connectors.
Below is an example configuration for a W61PC card setup:
The external FSK demodulator hardware is optional - it is only required if the customer wishes to use his
own demodulator hardware.
Mini-DIN Connector (EXT-DEM-IN/DIG)
W61PC Power Supply Ratings
