log analogue or pulse inputs (data sent by IP) and
monitor system information such as signal strength.

In addition the units can switch digital outputs and an optional relay board is available for this purpose (see below).

Configuration of the device is done via PC-based Configuration Tool software, with the device connected via RS-232 serial port.

Applications include:

  • SMS alarm and control
  • Pulse logging of rain gauges, water or electrical meters
  • Automated meter reading
  • ON/OFF control, eg irrigation pump

I/O’s:

Case studies of CYCON-1280

Why have 4 Recipient Groups?

The Recipient Groups feature is useful where you have different levels of escalation, or different working hours. For example you could connect your equipment to one input (or several inputs) of the CYCON-1280 via a timer switch that only operates Monday to Friday during business hours, and another input via a second timer switch that operates on the weekend or nights. Then you can have a different group of people alerted at those different time periods, according to their working hours.

Another application is if you have one recipient group for operations staff, and another group for management. Then you can set up the inputs and groups so that non-critical alarms go to the operations staff only, and critical alarms get sent to management as well.

Modem Information

Hayes command set: click here (modemhelp.net) or here (Wiki) Rockwell chipset commands (RC56D/RC336D & LD): click here (.pdf file 492KB)
To enter command mode: wait 3 seconds  +++  wait 3 seconds, then AT commands can follow.
To set a modem to answer after 2 rings: ATS0=2    Save this with AT&W

For technical reasons, a Telstra SIM card is recommended for use in Australia, with a “Data” number.
There are two kinds of ‘phone numbers: Voice, and Data.
To be able to receive data calls on the GSM modem you need a “Data” number.
With a Voice number, outward data calls can be made, but the GSM modem will not answer incoming data calls.

GSM modems can be dialled up (and data transmitted) from a normal modem on a land line, provided that the SIM cards in the GSM modems are data enabled.

If you are having modem problems, output the active profile (current settings) using AT&V.  Email this to us (see top of page),
or print and fax it to Esis Pty Ltd, fax 02 9481 7420.

GPRS(General Packet Radio Service)
These GSM modems have GPRS capability. Subscribers log in and remain online.

User pays for the actual data transmitted, not for the time connected.

Its packet structure corresponds to the IP protocol. GPRS helps transmit large amounts of data in a very short time via mobile access.

Applications such as mobile Internet, fast e-mail transmission and e-commerce now make real economic sense.

With GPRS, when the modem connects, the network generally allocates an IP address dynamically to the modem, which is then used until it disconnects.

For GPRS the networks charge according to data packets sent, not according to how long the modem is connected.

UMTS – Universal Mobile Telecommunications System www.umtsinfo.co.uk (new tab)
The goal of the third generation UMTS standard is to unify fixed line telephony, internet, mobile, and network technologies into one global roaming capable standard.

UMTS is the third generation (3G) of mobile telecommunications technology. It is the latest commercially available technology that mobile phones, PDAs, and smart phones are using today. With this development, internet access (email and web browsing), video calling and messaging, and text messaging (SMS) are now possible along with traditional phone tasks.

Difference Between GSM, UMTS, 4G UMTS and EDGE
http://www.differencebetween.net/technology/difference-between-gsm-and-umts/#ixzz1C0cK1Scq (new tab)
GSM networks support 14.4kbits/s, or 28.8kbits/s.

Common belief is that UMTS can support 2Mbit/s, although its actually a maximum of 1920kbits/s, even then this is a very generous figure, most users should expect performance of 384kbits/s, this is due to distance, and load on the network.

Unlike GSM, UMTS is mainly based on CDMA (Code Division Multiple Access) scheme and now combines it with TDMA. With countries that support it, it may have set different spectrum, thus interoperability may not work fully when moving from one nation to another nation with drastically different spectrum.

UMTS is not compatible with GSM, but UMTS phones which are currently sold are dual mode, which means they can work on GSM as well as UMTS. If a user wants to make a call, but is out of a UMTS area, the device can use GSM. Even if this happens while on a call, the phone can be switched over to the GSM network, completely uninterrupted, transparently to the end user.

Although the newer wave of 3G phones can be used on both networks, GSM phones can’t be used on UMTS networks.
4G In 4G UMTS, data must download at a rate of 100 megabytes per second in mobile devices and at 1 gigabyte per second for electronics connected to a local wireless access hub.

Both 3G UMTS and 4G UMTS require the simultaneous transfer of voice and data, which was a requirement first established during the switch from second generation to third protocol. 3G UMTS and 4G UMTS can both transfer information using the same infrastructure.

EDGE: Enhanced Data Rates for GSM Evolution (EDGE). UMTS and EDGE are competing mobile communication technologies. These are both third generation (3G) communication technologies with new features and capabilities over GSM. Generally, these systems differ mainly in speed and the way that users access the networks that transmit radio signals. Typically, the maximum data rate for EDGE is 236 kilobits per second (kbps).

RoHS is the acronym for Restriction of Hazardous Substances – EU Directive 2002/95/EC: restriction on the use of certain hazardous substances in electrical or electronic equipment sold or used in the European Union after July 1, 2006. These hazardous substances include: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers.

GPRS General Packet Radio Service: An enhancement to the GSM mobile communications system that supports data packets.
GPRS enables continuous flows of IP data packets over the system for such applications as Web browsing and file transfer.
GPRS differs from GSM’s short messaging service (GSM-SMS) which is limited to messages of 160 bytes in length
