INTERNAL MODEM OPTION

Dataprobe offers the following internal modem options with the 4P-MAS:

MOD-24      2400bps Modem
MOD-144    14.4 Kbps Modem
MOD-336    33.6 Kbps Modem

These modem options, when ordered with the 4P-MAS are supplied factory installed.  They can also be
ordered separately for field installation.   Information on field installation is supplied with the modem.

Connection to the dial line is made using a RS-232 to Modular Adaptor, 

Model MA-CAS

, supplied with

the modem.  This adaptor connects to the Master Port and to an RJ11 Modular Jack.  The modem’s
FCC registration and AT command set are supplied in a separate document.
With the modem installed, the Master Port
RS-232 port can still be used.  With the
Modular Adaptor removed, an external
modem or terminal (with null cable) can be
directly connected to the Master Port.  The
connections for the internal modem use pins
11 and 25, to avoid conflict with directly
connected devices.
