Logic IO Newsletter
January 31, 2011

Dear RTCU User,

Welcome to the first newsletter of 2011!

Looking back on 2010, the year has been very hectic, challenging, but equally exciting for Logic IO. The demand for our products has been steadily increasing, but at the same time we have been challenged to balance the fine art of supply and demand, as the electronic components eco-system has presented us with ever increasing lead-times and prices.
We have managed extremely well under these conditions and have delivered all major orders within the expected time-frame and with no price increase!

In 2010 Logic IO also managed to maintain the prestigious AAA (Triple-A) credit rating for the 3rd year. Only approximately 1% of all Danish companies are currently able to maintain the AAA rating!

The criteria to obtain the AAA rating is:

AAA – Highest credit worthiness
Applicable on limited companies only. Also, the company turnover must be higher than 2 M SEK, it must have existed for at least 10 years and ratios need to be substantially higher than industry average.

In this newsletter we are equally proud to present another member of the RTCU AX9 series -
the RTCU AX9 eco. Like all our 'eco' products, such as the MX2i eco+ and the RTCU DX4 eco, this product variant is an economical variant based on the full featured 'pro' version, but with a perfect balance between features, performance and price. The RTCU AX9 eco is no exception with a very impressive list of standard features - such as IVR (Interactive Voice Response) and on-board battery.
With the launch of the RTCU AX9 eco, the RTCU A5i will no longer be available and the transition from the RTCU A5i/A9i to the new RTCU AX9 series is now completed.
Please read more about the exciting new RTCU AX9 eco below.

In this newsletter we also have the pleasure of presenting the following list of new software releases:

  • X32 firmware V2.30 for the RTCU MX2i series and RTCU DX4 series.
  • X32 firmware V2.31 for the RTCU AX9 series.
  • RTCU IDE V5.80.
  • Communication Support Package (CSP) V1.33.
  • Application Note: Remote serial port using virtual device driver.

RTCU AX9 eco


The RTCU AX9 eco is a low-cost version based on the full-featured and powerful RTCU AX9 pro, that still hosts a long list of advanced features.

Compared to the RTCU AX9 pro the RTCU AX9 eco differs on the following features:

  •  No 868 Mhz ISM RF band transceiver.
  •  No SD-CARD reader.
  •  No secondary RS232 port.
  •  No standard RS485 port.
  •  No support for accessories such as Bluetooth, VGA Camera, Ethernet/WiFi.
  •  No analog outputs and only two analog inputs.
  •  No expansion slot.
  •  Low-capacity battery.
  •  No Enhanced X32 memory support. 

The RTCU AX9 eco has been designed ground up for professional wireless industrial applications with its strong on-board I/O capabilities and multiple communication interfaces, such as: 1-Wire, USB, RS232 and optional RS485. For world-wide operation the RTCU AX9 eco offers full quad-band GSM support with internal or external antenna.

The RTCU AX9 eco offers many other sophisticated features such as: a 512 Kbyte internal flash drive with a FAT32 compatible file-system for easy sharing of files locally and remotely. There is optional support for a Mobile Data Terminal for advanced user interaction.

The RTCU AX9 eco is based on the well proven RTCU X32-architecture sharing powerful features such as: IVR (Interactive Voice Response) implementation using Voice/DTMF, SMS/PDU messages, optimized host implemented TCP/IP stack with full support for the Logic IO Gateway concept. Using the Logic IO VSMS (Virtual SMS) technology SMS, GPRS and CSD (Datacall) merge together, allowing any RTCU application, that uses the VSMS-messages paradigm, to transparently send / receive messages using either SMS, GPRS or CSD (Datacall) without any changes to the software already developed.

The unit has full SMTP support for sending e-mails with attachments and file transfer with FTP for easy exchange of information with external sources.

The RTCU AX9 eco is fully programmable using the user-friendly Integrated Development Environment (RTCU IDE) running under Windows. In the environment the complete application is developed, simulated and finally transferred to the unit via a standard USB port or remotely using GPRS or CSD (Datacall).

The RTCU AX9 eco is also the logical successor to the former RTCU A5i/A9i products. For a brief description of the enhancements and transition please read the RTCU AX9 Series Product Information Bulletin.

The RTCU AX9 eco feature-list includes

  •  Based on the well proven X32-architecture.
  •  100% software compatible with all current and past RTCU units! 
  •  Quad Band GSM Engine for world-wide operation.
