with industrial-strength resistance to EMI/FRI

Key Features

  • Strongly resists the electro- magnetic interference typical of industrial environments.

  • Is V.34 compliant, supports data rates up to 28.8 Kbps and a standard AT command set.

  • Can be fitted with optional RS485 module in order to relay data from RS485 industrial equipment.

  • Can redial, AutoDial, speed dial, fall back-dial, and supports V.23 and Bell 103 and 212A.

  • Has a full set of LEDs and performs several loopback tests for easy monitoring.

  • Compatible with both dialup lines and 2-wire leased lines.

  • Predrilled for bolt down.

 

Do you need to put a modem in the radio/electronic equivalent of "harm's way" - near an assembly line, generator, compressor, or other source of electromagnetic or radio frequency interference. The Industrial Modern 288 (IM288) is tailor-made for that job, with specially insulated circuitry and a tough metal housing that's pre drilled to be bolted down wherever you need it. With an optional RS-485 Module attached to its DTE connector, the IM288 can talk directly to industrial devices that use the 2- or 4-wire TIA RS485 interface.

The old and reliable modems (202T/S) slow, mysterious, and inflexible something like an old Soviet tractor - not the IM288! It can make connections with other V.34-compliant modems at speeds up to 28.8 Kbps and use the AT command set. If your hardware can use up to 115Kbps throughput this modem might be the answer to the higher data speeds needed buy the new applications.

With eight LEDs (power, DTE ready, carrier, transmit, receive, high speed, auto-answer, and off-hook) you can get quick snap shot of what's going on or your modem and phone line. The IM288 supports a full range of standard AT commands, S-registers, loopback tests, and result codes, so you can easily configure and troubleshoot your modem.

The IM288 has many useful dial and connection features - 1. you can set it to dial a number as soon as you turn it on and to redial or try a different number if there's no answer or the line is busy - 2. store up to ten numbers in memory for speed dialing
3. communicate with all Bell-standard modems.

The IM288 supports 2-wire leased lines and can be configured to automatically establish leased line connections at power-up.

Don't be left out in the cold! Send or receive data in even the harshest cold or hot industrial environments with the Extreme Climate Industrial Modem. Since it works at temperatures ranging from -40 to 185' F (40 to 85' C), it's perfect for hot boiler rooms, or even outdoor environments that get frigid cold winters and/or sweltering hot summers.

The Modern is configured for industrial data communication between a PLC and a PC. It's intended for use as a remote / receiver in industrial applications under temperature conditions that would make a standard dialup modem unreliable.

The modem gives you steady data transfer at speeds up to 9600 bps.

Keep in mind that this is a basic model. Many options such as data compression, leased line operation, error correction, or external telephone jack are not available with this modern. If you need these additional options, call our technical support experts. They can recommend the modern that's best for your application.

Since the Extreme Climate Industrial Modern is pre-configured at the factory, the only command strings you need are for dialing and hang-up. You can enter these instructions in either a PC program or a PLC configuration program.

Operating the modem in "sleep mode" ensures low power consumption and makes it ideal for battery- or solar-powered applications.

An RJ-11 cable is included with your modern for connecting to the phone line.

This reliable basic modem works at temperature extremes-from -40 to 185F (-40 to 85C).


Technically Speaking

 

The Modern has four front panel LEDs...

    SmdData(TXD) Flashes green when the modem is sending data to the remote modem or when receiving data from the local computer.

    Receive Data (RXD)Flashes yellow when the modem is receiving data from the remote modem or when sending data to the local computer.

    Carrier Detect (CD)Flashes amber when the remote modem carrier is detected.

    Power-Steady red is on when there is power to the modem.
