MMX 4711 Cascading It is possible to cascade the output from one or more MMM 4711 s into the inputs of another MMM 4711 provided the total sum of the ASI inputs of the final MMM 4711 does not exceed its set ASI output rate For example it is possible to have say four 2Mb s ASI streams combined together with one MMM 4711 with its output rate set to 10Mb s and use this combined 10Mb s ASI stream and feed it into one of the input ports of another MMN 4711 thus allowing more ASI streams to be combined at the output of the second MMM 4711 It is even possible to cascade this output into yet another MMM 4711 providing that the sum of the inputs into this unit does not exceed its set output ASI rate At the receiving end the MMX 4711 s are arranged in the reverse order to give the original ASI streams For example ASI 1 ASI 1 ASI 2 ASI 2 ASI 3 ASI 3 ASI 4 ASI 4 ASI 5 ASI 5 ASI 6 ASI 6 ASI 7 ASI 7 ASI 8 ASI 8 ASI 9 ASI 9 ASI 10 ASI 10 IRT Electronics Pty Ltd www irtelectronics com Page 11 of 20 Revision 04 MMM 4711 amp MMX 4711 MMN 471 1 Rear Assembly Connections Alarm O P ASI 1 I P FIE asi21P ASI 3 I P a AEN 2 asi 4 P SK4 OUTI SK3 W OUT3 ASI O P 1 ASI O P 2 Data I P om RS 232 Data Input The RS 232 data input port is via a 10 pin HE14 style of header Pins 1 2 and 7 are connected together on the PCB Pins 9 and 10 are both earthed Pin 3 is the RS 232 receive data RXD connectio

6. Is It SNMP stands for Simple Network Management Protocol It is an application layer protocol for managing IP Internet Protocol based systems SNMP enables system administrators to manage system performance and to find and solve system problems SNMP runs over UDP User Datagram Protocol which in turn runs over IP Three types of SNMP exist SNMP version 1 SNMPv1 SNMP version 2 SNMPv2 and SNMP version 3 SNMPv3 It is not the intention here to discuss the differences between various versions only to bring attention to the fact that IRT Electronics modules fitted with SNMP capability use SNMPv1 An SNMP managed network consists of three key components Network Management Systems NMS agents and managed devices An NMS is the console through which the network administrator performs network management functions such as monitoring status e g alarm states and remote controlling of a set of managed devices One or more NMS s must exist on any managed network Generally the NMS is a computer running third party SNMP control software There are a number of third party SNMP software applications currently available on the market An NMS polls or communicates with an agent An agent is a network management software module that resides in a managed device An agent has local knowledge of management information and translates that information into a form compatible with SNMP The agent therefore acts as an interface between the NMS a
