CDM-600L Satellite Modem
Physical Description
IEC AC line input connector
The IEC line input connector contains the ON/OFF switch for the unit. It is also fitted
with two fuses - one each for line and neutral connections (or L1, L2, where appropriate).
These are contained within the body of the connector, behind a small plastic flap.
•
DC Power input connector
The input connector for DC power is Corcom PN PS000DD6D, which mates with Molex
connector 03-12-1026 using Molex 18-12-1222 sockets. It is also fitted with two fuses -
one each for positive and negative DC input connections. These are contained within the
body of the connector, behind a small plastic flap.

IMPORTANT
RX and TX IF connectors (J1 and J2)
The TX-IF connector is a 50 Ω Type N female. The RX-IF connector is either a
50Ω Type N female or a 75Ω Type F female.
Data interface connector (P3B)
The Data connector is a 25-pin 'D' type female (DB25-F). This connector conforms to
the RS-530 pinout, which allows for connection of different electrical standards,
including RS-422, V.35, and RS-232. A shielded 25-pin 'D' type provides a very solid
solution to EMC problems, unlike the sometimes-used V.35 Winchester connector.
IMPORTANT
Use T3.15A, (slow-blow) 20mm fuses.
Use T2.0A, (slow-blow) 20mm fuses if modem has no internal BUC power
supply
Use T8.0A, (slow-blow) 20mm fuses if modem has internal BUC power supply.
For continued operator safety, always replace the fuses with the correct type and
rating.
It is the responsibility of the user to provide the appropriate cables to
connect to this RS-530 connector
