Key Features:
  • IoT Connectivity for existing and new equipment deployments
  • Easily connect RS232 legacy devices over cellular networks
  • Makes remote control and monitoring easy and reduces cost.
  • Requires a minimum of technical knowledge
  • Application-ready with screw terminals and rugged packaging.
  • Control via SMS or CloudAXS website

ActivConnect and CloudConnect are based on the same reliable modem architecture with screw terminals for ease of installation.

ActivConnect

ActivConnect devices are available with 2G GPRS and 3G UMTS options and are configured by sending SMS (text messages) to the modem.  The configuration enables remote control of relays and reading the status of inputs.  In addition, the user can pre-program email addresses or phone numbers to be contacted in the event of an input changing state.

CloudConnect

CloudConnect devices are also available with 2G GPRS and 3G UMTS options but all configuration is done via the CloudAXS website.  Here you can assign names to the device inputs and output relays and set logic of how and when an alert is triggered.  CloudConnect is great for one or many devices and makes configuration a very straightforward process requiring little technical knowledge.

Extend your reach with Siretta quality, low-loss RF cables

Acquiring RF signals in poor reception areas (2G/3G/4G), short range wireless communication (line of sight for 433 and 868 MHz) or WifI connection in large buildings will require high gain antennas placed as high as possible to get the best reception. Problem is that the longer the cable length is from the RF equipment to the antenna, the higher the losses and consequently poorer reception. RG174 and RG58 are standard cables that everyone use for RF work, however the losses per metre escalate rapidly the higher the frequency goes. Antennas with cable lengths of 10M, 15M or 20M will suffer considerable loss over the length. It means that a more powerful transmitter and /or a more sensitive receiver is required. This all comes at a price in one way or another. Better to not have the losses there in the first place. Standard RG58 cable has an approximate loss per metre of 1dB at 2.5GHz - Wifi and Euro 4G frequencies. Bear in mind that a loss of 3dB of signal is actually halving the signal strength it is easy to see why systems are not very sensitive if they have long and standard cables to the antenna. Now take the LLC200 low loss RG58 equivalent it has a solid copper core and 2 levels of shielding and special connectors to accommodate the cable. It has a 0.55dB loss per metre at the same 2.5GHz frequency. Bearing in mind the logarithmic nature of measuring in decibels the signal arriving at the end 20M of RG58 cable at 2.5GHz is about 0.07% of what went it to the cable. Alternatively, using the LLC200 cable the signal arriving at the end of the cable is around 12% of what went in. 0.07% versus 12% is a massive difference in signal strength. This is the case for Siretta\'s low loss cable range! Siretta’s low loss extension cables provide the best solution in minimising losses and giving the required RF signal for a successful and continuous wireless connection. Generally speaking low loss cables are not very available as a stock item, however at Siretta we have a complete range of cable lengths and connector styles from stock or very short lead time. Available in cable lengths from 5m to 20m with a vast number of connector combinations, including, SMA, FME, N-Type and TNC etc. Look for the white cable marker telling that it is a Siretta quality cable, its part no. and length.....
