3. CMC-TC Master
3.1 Description
The RITTAL CMC-TC Master is a function block making the administration, co-ordination,
documentation, and alarm indication of the monitoring system CMC-TC more comfortable
and supporting additional functions. The configuration is consisting of an Embedded Linux
PC with integrated 10-fold hub in the 1 U 482.6 mm (19”) enclosure, to which up to 10
processing units can be connected. An integrated 10/100 BaseT interface (Ethernet
interface) allows the Master to integrate the connection into the network environment of the
company. The Master can be operated off the network using the console connections
(2xPS/2, 1xVGA). This means the Master can be accessed locally or via the network.
A visible or audible alarm can be implemented using the integrated alarm relay.
The CMC-TC Processing Units are linked up by Cat5 cabling with the CMC-TC Master
installation. The data connection into the network is made via the Embedded-Linux PC. To
guarantee the connection to the network is secure, 128-bit SSL encryption is integrated.
Access to the integrated web browser of the Master is possible through a standard browser
(Internet Explorer, Mozilla Firefox, etc.). The CMC-TC Master supports the TCP/IP, SNMP,
TELNET (TeraTerm), SSH and HTTPS protocols.
The network protocols are used for communication (password and status query, switching
commands, and alarm signals) between the CMC-TC system and the authorized users in the
network (network, internet and intranet).

Appendix C Functional diagram
The Rittal CMC-TC Master is platform-independent as long as the platform has a network
connection and a web browser available. The SNMP functionality is also platform-
independent and must support the SNMP V1.0 network management protocol. In addition,
the CMC-TC Master supports the Standard-MIB II. The private MIB is part of the scope of
supply; see CD Rom (CMC-TC-Master.MIB).
