1 - Introduction
This is our standard CTXL-TRH recorder, except that the temperature/humidity
probe is wireless. The wireless probe consists of a temperature/humidity
wireless transmitter and a wireless receiver.
The wireless transmitter has a built-in temperature/humidity sensor that
measures the air quality (Temperature & Humidity). It then transmits the data to
a wireless receiver thru an RF link. The transmitter is operated from one AA size
lithium battery and/or a DC adapter input. The transmitter also has two LED
indicators. One Green LED is for transmission indication. One Red LED is for
low battery indication as well as other wireless communication errors.
The wireless receiver plugs directly to the circular chart recorder where a
temperature/humidity probe is normally plugged into. The wireless receiver
acts as a probe, so the wireless RF link is totally transparent to the circular chart
recorder. The recorder thinks that it is directly connected to the probe. This
design allows us to offer the wireless probe as an option to all existing recorders
in the field. There is no internal upgrade required to make a standard circular
chart recorder wireless.

2 - Configuration
The wireless transmitter and receiver have the following factory default
configuration:
Transmission time interval: 2 seconds
Channel 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 receiver
if the factory configuration is satisfactory. However, if the user wants to change
the configuration, then you need to run the configuration software that comes
with the unit. Through the configuration software, the user can change the
transmission interval, channel frequency and the unit ID number. First install the
configuration software on your PC.
Configuring the wireless Transmitter – Turn off the battery power. Connect the
transmitter to the USB port of the PC with the cable provided. Run the
configuration software. Figure 8 shows the main menu of the software. The
buttons and the menu selections are described as follows:

Unit ID - You can select a unit ID from 00 to 63.
Figure 8. Wireless Transmitter, Main Menu
Addendum
M4098 CTXL Addendum
You can have up to a total of 64 wireless transmitters in one location with
different unit ID numbers, so that there will not be any conflict between any of
the transmitters.
If you select the Broadcast option, the transmitter will transmit to any receiver in
the area at the same frequency regardless of its unit ID number.
After saving the new configuration, exit the program. Un-plug the transmitter
from the USB port, turn the battery power back on and you are good to go.
Configuring the wireless Receiver – Unplug the receiver from the chart
recorder. 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 shows
the main menu of the software. The buttons and the menu selections are
described 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 the
transmitter being received by the wireless receiver. This is a guide to show the
user how to install the transmitter with respect to the receiver so that you
maintain good signal strength and as a result good and reliable RF
communication.
Program – It will save the new settings to the receiver.
Read – It will read the current settings of the receiver
Settings – It will take you to the communication settings menu
Frequency – You can select between 910/915/920 MHz frequencies.

Addendum
M4098 CTXL Addendum
You can have up to a total of 64 wireless receivers in one location with different
unit ID numbers, so that there will not be any conflict between any of the
receivers.
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 from
the USB port, set the slide switch to "Normal", plug the receiver back to the chart
recorder and you are good to go.

4 - Error Codes
Transmitter Error Codes
The wireless transmitter uses the Red LED to provide different error information
to the user and to the wireless receiver as follows:
2 Red LED Blinks means there is an RF communication error such as Framing,
CRC, buffer overflow, etc.
3 Red LED Blinks means that the transmitter fails to communicate with the
sensor probe
4 Red LED Blinks means Low Battery indication.
The highest priority error code is 2 blinks for RF communication error. The
lowest priority error code is 4 blinks to indicate low battery. If multiple errors
occur at the same time such as bad sensor probe and low battery, the
transmitter's red LED will blink 3 times. Only when this error clears, then the
transmitter's red LED will blink 4 times to indicate the low battery.
The red LED error reporting occurs every 30 seconds regardless of the
transmission time interval.
Receiver Error Codes
The wireless receiver basically reflects all the error codes of the wireless
transmitter as follows:
1 Red LED Blink means No good message has been received from the
transmitter within 4 transmission time intervals (like 4 minutes for 1 minute
time interval), or 30 seconds minimum. The receiver will continue to search for
the transmitter’s message 10 more minutes before deciding that the transmitter
is either off, out of order, or out of range at which point the receiver will shut
itself off to conserve power.
If the wireless transmitter is back on line after 10 minutes, then the user needs to
un-plug the receiver from the recorder and plug it back in to reset the wireless
receiver.
Addendum
M4098 CTXL Addendum
2 Red LED Blinks means there is an RF communication error such as Framing,
CRC, buffer overflow, etc.
3 Red LED Blinks means that the transmitter fails to communicate with the
sensor probe
4 Red LED Blinks means the transmitter’s Battery is low.
The highest priority error code is 1 LED blink for No good message from the
transmitter. The lowest priority error code is 4 LED blinks to indicate
transmitter’s low battery. If multiple errors occur at the same time such as bad
sensor probe and low battery, then the receiver’s red LED will blink 3 times.
Only when this error clears at the transmitter, the receiver will then blink 4 times
to indicate the next error, if any.
The red LED error reporting occurs every 10 seconds regardless of the
transmission time interval.
Any error code except for the low battery means Probe Error for the chart
recorder.
