2.5.2.8 Interface to PCB Modem Supply CS_M
The interface to PCB Modem Supply CS_M is realized by the connectors MO_SU/
and RS232_E/.
MO_SU/ delivers the voltage +26,5 for the modem supply generation, RS232_E/
receives the generated modem voltage +8V for the PCB Control CS_CI.
Connector denotation: MO_SU/
Type: multipoint connector 1 X 3 pin., 180°,
reverse terminal protection, MODU II
The function of the individual pins is given in the following table . The definition as an
input/output is seen with reference to PCB Control CS_CI.
