User Manual

11 - IntroductionThis is our standard CTXL-TRH recorder, except that the temperature/humidityprobe is wireless. The wireless probe consists of a temperature/humiditywireless transmitter and a wireless receiver.The wireless transmitter has a built-in temperature/humidity sensor thatmeasures the air quality (Temperature & Humidity). It then transmits the data toa wireless receiver thru an RF link. The transmitter is operated from one AA sizelithium battery and/or a DC adapter input. The transmitter also has two LEDindicators. One Green LED is for transmission indication. One Red LED is forlow battery indication as well as other wireless communication errors.The wireless receiver plugs directly to the circular chart recorder where atemperature/humidity probe is normally plugged into. The wireless receiveracts as a probe, so the wireless RF link is totally transparent to the circular chartrecorder. The recorder thinks that it is directly connected to the probe. Thisdesign allows us to offer the wireless probe as an option to all existing recordersin the field. There is no internal upgrade required to make a standard circularchart recorder wireless.Figure 1 shows Temperature/ Humidity wireless transmitter, GeneralDimensions, Labels and descriptions.Figure 2 shows the Battery location in the wireless transmitter.

52 - ConfigurationThe wireless transmitter and receiver have the following factory defaultconfiguration:Transmission time interval: 2 secondsChannel Frequency: 915 MHz (US & Canada) or 868 MHz (Europe)Unit ID: 00 (Both transmitter & receiver)The user does not have to do any configuration to the transmitter or the receiverif the factory configuration is satisfactory. However, if the user wants to changethe configuration, then you need to run the configuration software that comeswith the unit. Through the configuration software, the user can change thetransmission interval, channel frequency and the unit ID number. First install theconfiguration software on your PC.Configuring the wireless Transmitter – Turn off the battery power. Connect thetransmitter to the USB port of the PC with the cable provided. Run theconfiguration software. Figure 8 shows the main menu of the software. Thebuttons and the menu selections are described as follows:Run – It will display the temperature/humidity in real time.Program – It will save the new settings to the transmitter.Read – It will read the current settings of the transmitterSettings – It will take you to the communication settings menuFrequency – You can select between 910/ 915/920 MHz frequencies.Time interval – You can select from 2 seconds up to 2 minutes.Unit ID - You can select a unit ID from 00 to 63.Figure 8. Wireless Transmitter, Main MenuM4098 CTXL Addendum Addendum
6You can have up to a total of 64 wireless transmitters in one location withdifferent unit ID numbers, so that there will not be any conflict between any ofthe transmitters.If you select the Broadcast option, the transmitter will transmit to any receiver inthe area at the same frequency regardless of its unit ID number.After saving the new configuration, exit the program. Un-plug the transmitterfrom the USB port, turn the battery power back on and you are good to go.Configuring the wireless Receiver – Unplug the receiver from the chartrecorder. Connect the receiver to the USB port of the PC with the cable provided.Set the slide switch to "Config". Run the configuration software. Figure 9 showsthe main menu of the software. The buttons and the menu selections aredescribed as follows:Run – It will display the temperature/humidity in real time from the transmitter.There is an RF signal strength gauge where it shows the signal strength of thetransmitter being received by the wireless receiver. This is a guide to show theuser how to install the transmitter with respect to the receiver so that youmaintain good signal strength and as a result good and reliable RFcommunication.Program – It will save the new settings to the receiver.Read – It will read the current settings of the receiverSettings – It will take you to the communication settings menuFrequency – You can select between 910/915/920 MHz frequencies.Time interval – You can select from 2 seconds up to 2 minutes.Unit ID - You can select a unit ID from 00 to 63.Figure 9.

7You can have up to a total of 64 wireless receivers in one location with differentunit ID numbers, so that there will not be any conflict between any of thereceivers.In order for a pair of wireless transmitter and receiver to communicate properly,the time interval, channel frequency and the unit ID should be the same for both.After saving the new configuration, exit the program. Un-plug the receiver fromthe USB port, set the slide switch to "Normal", plug the receiver back to the chartrecorder and you are good to go.Figure 10 shows the settings menu for selecting the COM port, and thetemperature Engineering unit.Figure 10.

Thelowest priority error code is 4 blinks to indicate low battery. If multiple errorsoccur at the same time such as bad sensor probe and low battery, thetransmitter's red LED will blink 3 times. Only when this error clears, then thetransmitter's red LED will blink 4 times to indicate the low battery.The red LED error reporting occurs every 30 seconds regardless of thetransmission time interval.Receiver Error CodesThe wireless receiver basically reflects all the error codes of the wirelesstransmitter as follows:1 Red LED Blink means No good message has been received from thetransmitter within 4 transmission time intervals (like 4 minutes for 1 minutetime interval), or 30 seconds minimum. The receiver will continue to search forthe transmitter’s message 10 more minutes before deciding that the transmitteris either off, out of order, or out of range at which point the receiver will shutitself off to conserve power.If the wireless transmitter is back on line after 10 minutes, then the user needs toun-plug the receiver from the recorder and plug it back in to reset the wirelessreceiver.M4098 CTXL Addendum Addendum
