Physical Installation

Connecting the Serial Ports

The four serial ports on the Accelerated 5400-RM provide console access to connected critical equipment through the cellular network, and optionally through a connected Ethernet LAN. Connect up to 4 of your network devices to the Accelerated 5400-RM serial ports using the Pinout information below.

You must use a cable with an RJ45 connector to connect to the 5400-RM with a RJ45, DB9F or DB9M connector, as determined by your device type, to terminate to your device. Consult the user guide for the device you are connecting to the 5400-RM to determine the connector type, cable type, and pinout positions for your specific device.

The serial ports are enabled by default. The network devices connected to the serial ports may be accessed using the aView terminal window, the local device GUI, TCP, telnet, or SSH connections. TCP, telnet and SSH connections to serial ports are disabled by default and must be enabled by a device specific configuration. Connect up to 4 of your network devices to the Accelerated 5400-RM serial ports using the 5400-RM pinout information below.

Connecting to the Site Networks

To use your wired network as an alternative network to access the devices connected to the 5400-RM serial ports, connect the LAN port on the Accelerated 5400-RM to your site Gateway. By default a DHCP request will be sent to the local Ethernet network.

  1. Plug the power supply unit into an AC power outlet and connect to the 12V DC lead (4 pin connector) cable.
  2. Using a customer provided CAT5 cable connect to your site gateway and the LAN port of the 5400-RM.

Serial Port Pinout and Use

The RS232 standard requires support for baud rates up to 9600 baud on shielded multicore cable up to 50 feet (15 meters) long. For the 5400-RM, the use of standard CAT 5 cables enables serial communication at all baud rates up to 50 feet. CAT5 unshielded twisted pair cable lengths much longer than 50 feet have been verified at 9600 baud but are non-standard and are not guaranteed.

The 5400-RM RS232 serial ports are DTE and have the following pin configuration.

Pin 1 RTS Request to send Output from 5400-RM
Pin 2 DCD Data carrier detect Input to 5400-RM
Pin 3 RXD Receive data Input to 5400-RM
Pin 4/5
Ground Signal ground
Pin 6 TXD Transmit data Output from 5400-RM
Pin 7 DTR Data terminal ready Output from 5400-RM
Pin 8 CTS Clear to send Input to 5400-RM

NOTE: ring indicate (RI) and data set ready (DSR) are not implemented

The serial ports use a female RJ45 jack to enable connection using UTP Ethernet cabling.
