Analogue modem 33.6 kbps
(RS-232 and TTL interface)

Digital modem ISDN-TA
(RS-232 and TTL interface)
The IO module modem PCD7.T8xx cannot
be connected to the PCD1.M2_ through the
TTLinterface(redatribbonconnector).The
cable is too short for this.
The RS-232 terminal block of the modem,
whose terminals are connected to a free RS-
232 port (modem-compatible!) represents
a solution.
“SlotA”ofthePCD1.M2_,ttedwithan
interface module PCD7.F121S is best suited
for this purpose.

For installation details, see manual 26-771 “PCD2.T8xx Modem Modules”
An alternative is the use of external modems, such as the Saia Q.MS716-KS1 at
the serial port “Slot A” with interface module PCD7.F121S.
