Special feature: Clock sourcing within the SYNCcable itself eliminates your need for a synchronous modem eliminator, allowing you direct connections to other local systems including direct 3745 Front End Mainframe connections! The SYNCcable+ diagnostic LED helps identify and correct field problems and makes installation easy, while its regulated power allows use of unregulated power supplies.

Special Adapter Cable: If you require an RJ-45 connection (for example to a Xylogics Terminal Server), you will require a special Async Adapter Cable, Part Number 6003075. This cable handles the RJ-45 to DB-25 connection/conversion and costs $30 (US$) each.

Cleo3780Plus provides full emulation of IBM 2780/3780 Remote Job Entry (RJE) stations through the Binary Synchronous Communications (BSC) protocol.  You get support for point-to-point and multi-point transfer, primary and secondary operation, and a 20-character "terminal ID."

3780Plus® Features and Capabilities

  • Unattended Operation - With Cleo 3780Plus, you can write simple scripts that run your batch transfer applications automatically, at any time, with no user interaction required.

  • Auto-Dial, Auto Answer - Cleo 3780Plus provides commands for automatically dialing your modem and instructing your modem to wait a specified amount of time for an incoming call.  Modem autodialing capabilities include :

    • Universal Data Systems (UDS) BSC
    • Racal-Vadic Synchronous Autodialing Language (SADL)
    • V.25bis - the CCITT dialing standard
    • Hayes AT Command Set for speeds of up to 38.4Kbps
  • Integrated Application Program Interface - IAPI lets you access data directly from the communications line, in real time, while preserving all of Cleo 3780Plus' powerful file transfer capabilities.
    Flexible Configuration - a wide range of configuration options, allowing you to fine-tune your communications environment at any time - from session to session, or even within a session. Configuration changes in one session can be stored to disk and re-used in later sessions

  • Perpetual Log File - This handy tool allows you to review all past Cleo 3780Plus transactions - from your very first session to the one you've just completed.

  • Modem Support - Cleo 3780Plus is designed for use with almost any major external synchronous modem and selected internal modem boards.

  • Custom Screens and Messages - You can easily modify your Cleo 3780Plus screens and messages, if your applications demand it.

  • Error-free data transfer. Cleo 3780Plus checks all data received and transmitted, and automatically retransfers the data if it funds errors.

  • Large data blocks.  Cleo 3780Plus can receive data blocks with up to 4,096 characters.  Maximum transmission block size can range from 2,048 to 4,096 characters, depending on  the platform.

  • Peer-to-peer - communicate with any device supporting 2780 or 3780 RJE protocols.  This can include another system running Cleo 3780Plus.

  • Quick Exit - With a single keystroke, you can instruct Cleo 3780Plus to hang-up the phone line and to exit to your operating system to run other applications or perform other tasks at any time.

  • Communications line monitor - Cleo 3780Plus monitors all communications activity during 2780/3780 RJE emulation.  This can be a valuable tool for troubleshooting.
