  • Page 7: Chapter 1 - Product Overview

    Chapter 1 - Product Overview Chapter 1 - Product Overview - Introduction The SNMP Access Gateway monitors serial (RS232) data streams for alarm conditions, and provides notification of alarm conditions by audible alarm, pager messages and SNMP traps. The SNMP Access Gateway may be used to provide legacy (non-network) equipment with the ability to generate SNMP traps when alarm conditions occur.

  • Page 8: Imux 2000 Information

    1.2 - - IMUX 2000 Information When used with the IMUX 2000 the SNMP Access Gateway connects to the remote port of the IMUX using port 1. Port 2 is used as a craft interface to both the IMUX and SNMP Access Gateway. A serial cable is supplied for connection from I/O 1 to the REMOTE port on the IMUX CM3R.

  • Page 9: Chapter 2 - Installation

    - Power Input The SNMP is powered through the IMUX 2000 chassis motherboard. The SNMP Access Gateway uses a maximum power input of approximately 5 watts, so the maximum current from the IMUX 2000 power supply is about 1 amp. MA810...

  • Page 10: Serial Ports

    Chapter 2 - Installation 2.3 - Serial Ports The I/O 2 serial port is configured as a DTE port using a male, DB-9 connector. The I/O 1 serial port is configured as a DTE port using an RJ-12 connector which is similar to that used on the COM ports of an IBM-compatible personal computer.

  • Page 11: Front Panel Items

    Chapter 2 - Installation 2.5 - Front Panel Items The front panel of the SNMP Access Gateway module has two push-buttons and 8 LED indicators representing status information about the SNMP Access Gateway. The reset (RST) button (S2) is used to reset the SNMP Access Gateway. After the RST button is held in for about 5 seconds, the SNMP Access Gateway will start sounding its audible alarm.
  • Page 12 Chapter 2 - Installation Each RS-232 port has two LEDs associated with it. The left LED is a received data (RXD) LED. The right LED is a transmitted data (TXD) LED. The TXD LED is normally on and green. The RXD LED is off when no cable is connected to the serial port, and on when a cable is connected.

  • Page 13: Chapter 3 - Basic Setup For Operation

    Chapter 3 - Basic Setup for Operation Chapter 3 - Basic Setup for Operation 3.1 - Network Setup As with all TCP/IP- or SNMP-based devices, the SNMP Access Gateway requires an IP address to be assigned to each unit in order to send and receive TCP/IP or SNMP data. The SNMP Access Gateway may operate with either a statically or dynamically allocated IP address.

  • Page 14: Connections

    Chapter 3 - Basic Setup for Operation 3.3 - Connections A connection may be made to the SNMP Access Gateway via a network connection. When a connection is made, the user is provided with a menu from which the desired mode of the connection is established. The user may select to enter a command processor mode of operation, or may select a pass-through mode of operation.

  • Page 29 Chapter 6 - Pass-Through Mode In pass-through access mode, each character the user inputs by network connection is passed to the serial I/O port, and each character which is received by the serial I/O port is passed through to the network connection. During this time, the data from the port is NOT processed by the event and alarm evaluator, so no alarm records are detected during this pass-through access.

  • Page 30: Chapter 7 - Console Mode

    Chapter 7 - Console Mode Chapter 7 - Console Mode When the serial I/O ports are in console mode, characters which are received on one serial I/O port are sent out the other serial I/O port. This allows the SNMP Access Gateway to be placed in-line between two piece of equipment (such as a control console and a piece of equipment, hence the console mode name), and monitor the data flow between the devices for alarm conditions.

    A new software application may be loaded into the SNMP Access Gateway by loading a file named ‘NEWAPP’ into the SNMP Access Gateway. Only an application program file made available by RFL should ever be loaded into the SNMP Access Gateway as an application file. Other files will not properly execute, and will thus result in the SNMP Access Gateway simply entering load mode, awaiting the loading of a valid application.
