GSM Modem Increases Mobile Telemetry Reliability

A Jekyll Electronic Technology product story

New GSM Modem increases mobile telemetry reliability for low power equipment.

A new industrial modem that enables manufacturers and users of remote low power data collection equipment to communicate across mobile GSM networks has just been launched by Jekyll Electronic Technology.

The Telemodem2 Mobile is a comprehensive, highly reliable GSM modem that adds value to any remote meter or monitor where host power is available but limited.

Electronics engineers will also benefit from the easy installation and set-up.

The Telemodem2 Mobile requires very little host power (configurable to 10milliWatts for operational use, and 5 microAmps on standby).

Integral to its success is the ability to draw power smoothly without requiring high pulses of current from the power supply.

Interchangeability with Jekyll fixed line modems makes the 'Mobile' a cost-effective option, so users can gradually incorporate a mobile telemetry capability into their existing set-up without having to make changes to host equipment.

Data ports are compatible with both logic or RS232 signal levels, which provides simple and flexible interfacing for a wide range of host meters and monitors.

Like other Jekyll modems, the 'Mobile' is designed for demanding remote telemetry applications in Automatic Meter Reading (AMR), environmental monitoring, plant condition monitoring, and general industrial telemetry.

Flexibility in supply voltage enables the unit to link up to battery powered data loggers as well as direct power supplies in process plants.

The unit is small enough to sit comfortably under the terminal cover of a typical electricity meter for AMR applications, where it can operate from the meter's internal power supply.

Until now, the high pulse requirements of typical GSM modems rendered them awkward for use with low power equipment.

Larger batteries were also needed in battery powered equipment to cope with the continuous operational demand, and the differences in power supply voltage and interface voltage levels caused interfacing problems with users' equipment.

Jekyll's Telemodem2 Mobile now solves all these problems.
