Modem 1200 baud 500FSD10
EDS500 series - FSK modems
Application, characteristics and technical data have to
be taken from the hardware data sheet:
500FSD10 Data sheet 1KGT150982
Operation
The 500FSD10 modem is a CCITT V.23 modem for
snap-in DIN-rail mounting. V.23 operates with the
frequency shift keying method (FSK). The modem can
operate in two- and four-wire connection. The mode of
operation is set by means of a twelve-fold DIP-switch.
Connections
Power connector for compact devices (X1)
The EDS500 series devices are equipped with a wide
range power supply for voltages between 24 and
60 Volts (power consumption see device label). The
connector is a 3-pin Phoenix plug with screw terminals.

Due to the internal overvoltage protection,
interrupt any connection to ground of the device
for the time of the measurement before you carry
out isolation measurement. This includes the
earthing of the hat rail as well as all shields of all
transmission lines and supply feedings. RJ-12 plugs
or RJ-45 plugs can establish earthing via the shield.
Serial Interface to DTE (X2)
The RJ-45 connector X2 forms an RS-232-D interface. If
the modem is connected to a terminal unit, an adapter
cable has to be used which connects the pin pairs.
