Sensorsoft Thermometer User’s Manual
Overview
The ST6105J, ST6105C and ST6154J Soft Thermometers are RS232 compatible serial devices
based on the Sensorsoft Device Protocol (SSDP). The ST6105C and ST6105J have a built-in
temperature sensor and are intended for applications requiring measurement of temperature in
heated or air conditioned rooms and warehouses. These products are not conformal coated and
are therefore not intended for environments with high moisture or condensation.
The ST6154J has an external stainless steel probe for measuring temperature in the following
applications or environments:
outdoors
refrigerators, freezers and cold rooms
pools and saunas
in liquids or on pipes
Only the probe portion of the ST6154J is suitable for exposure in the above listed environments.
The plastic electronic housing must be protected from moisture, condensation and sunlight (UV).
Sensorsoft devices offer the following benefits over other RS232 serial devices:
Powered from the serial port (no external power or battery required)
CRC error detection (detects transmission errors and improves reliability) (SSDP only)
Virtually unlimited cable lengths (1000 ft) (SSDP only)
Plug and go operation (little or no user configuration required)
Sensorsoft makes several SSDP-compliant software applications that permit you to read these
thermometers, send alerts, record and (in some cases) graph data. These include:
Sensorsoft Remote Watchman Client (RWMC) for Windows
Sensorsoft Remote Watchman Enterprise (RWME) for Windows
Sensorsoft Serial Communications Tool (SCOM) for Linux and UNIX
Sensorsoft Alert Appliance (SSA)
In addition, there are many manufacturers who provide support for Sensorsoft devices within
their products. Some of these include:
ServersCheck Sensor Gateway and software
Lantronix SecureLinx (SLC) Console Manager
Evertz, Harris and Miranda/Grass Valley broadcast TV products
As of firmware version 6.5, Sensorsoft Thermometers respond to Simple Text Commands when
used with a text-based terminal or scripting language. Additionally, we’ve provided several
means for customers to write software integrating Sensorsoft devices into their systems. This is
discussed further in the section, Writing custom software programs for the Sensorsoft
Thermometer.
