  • Page 4: About This Manual

    This document contains information about using the Sensorsoft Temperature and Humidity Meter. When other sections of this manual are referenced, italics are used. The Sensorsoft Temperature and Humidity Meter may be referred to as a device, Sensorsoft device or SSD (SensorSoft Device) throughout the manual. Glossary of Acronyms RWME –...

  • Page 5: Overview

    Overview The SS6610J and SS6610C Sensorsoft Temperature and Humidity Meters are RS232 compatible serial devices based on the Sensorsoft Device Protocol (SSDP). The SS6610J and SS6610C have built-in temperature and humidity sensors and are intended for applications requiring measurement of temperature and relative humidity in heated or air conditioned rooms and warehouses.

  • Page 6: Installing The Sensorsoft Temperature And Humidity Meter

    If the housing needs to be cleaned, use a damp cloth or vacuum cleaner. Use a Velcro fastener (P/N F1000 or F1001) to affix the Sensorsoft device to a stable surface. Connecting the Sensorsoft Temperature and Humidity Meter to a...
  • Page 7 Note the physical port number where you plugged the cable into your computer or device/console server. If the Sensorsoft device is being plugged into a Windows based computer that has only one COM port, the port number is usually COM1. If you are using a USB to serial adapter, you need to refer to the operating system’s serial port (COM) listing.

    305 m (1000 ft) using SSDP-compliant software. You may connect the Sensorsoft device to the port with as little as three wires (RX,TX and GND), using inexpensive unshielded telephone wire. However, the host may need to set the number of retries high in order to overcome the effect of occasional noise/interference and would also require the use of an external power supply (PA6106 or PA6206) at the Sensorsoft device.
  • Page 15 The Sensorsoft device modular-jack (RJ-45) connector uses the same UTP wire map as 10- BASE-T. It is therefore possible to use this type of cabling system for Sensorsoft devices. PIN-OUT OF THE MODULAR 8 POSITION JACK/PLUG ON A SENSORSOFT DEVICE Note: Terminal No.

  • Page 17: Writing Custom Software Programs For The Sensorsoft Temperature And Humidity Meter

    Sensorsoft Device Protocol (SSDP) for Advanced Programmers This software method is the most advanced way of supporting Sensorsoft devices. It has several advantages over the Simple Text Commands Interface discussed above. These include:  CRC error detection for use over long serial cables (1000 ft) ...
  • Page 18 NULL bytes In order to make use of the port-powered feature of the Sensorsoft device, you must enable serial port lines DTR and RTS when the port is opened. A delay of 1-2 seconds is required after opening the serial port before any commands are sent to the Sensorsoft device.

In the examples below, the last two bytes in each command string are CRC bytes that were pre-calculated.
  • Page 20 A two byte (16 bit) Cyclic Redundancy Check. This placeholder is filled with CRC bytes calculated by the Sensorsoft device on the entire packet from the RESPONSE byte to the last DATA-byte. These bytes allow the host to verify the integrity of the response packet. You may choose to use or ignore these bytes depending on your programming skill or application.
  • Page 21 A “logic one” condition on any of these bits indicates the condition is set or active. Otherwise, they are reset to “logic zero”. It’s a good practice for the host to check the status of the Sensorsoft device regularly in case a bit status changes.
