Getting Started

InTempConnect is web-based software where you can monitor CX450 logger configurations and view downloaded data online.
Using the InTemp app, you can configure the logger with your phone or tablet and then download reports, which are saved in the app and automatically uploaded to InTempConnect. The CX5000 Gateway is also available to automatically configure and download loggers and upload data to InTempConnect. You also have the option to use the logger with the InTemp app only.
Follow these steps to begin using the logger:

1. Set up an InTempConnect account. Follow all steps if you are a new administrator. If you already have an account and roles assigned, follow step c.
   If you are using the logger with the InTemp app only, skip stepping 2.
   a.
   b.
   c. Click Settings and then Users to add users to your account. Click Add User and enter the email address and first and last name of the user. Select the roles for the user and click Save. New users will receive an email to activate their user accounts.

2. Set up the logger. Insert two AAA batteries in the logger, observing polarity. Insert the battery door in the back of the logger making sure it is flush with the rest of the logger case. Use the included screw and a Phillips-head screwdriver to screw the battery door into place.

InTempConnect users: If the profile does not yet appear in the app, close and then reopen it, and repeat steps a and b. In addition, if trip information fields were set up, you will be prompted to enter additional information. Tap Start in the upper right corner when done.
   Note: You can also use the CX5000 Gateway to automatically configure loggers. See www.intempconnect.com/help for details.
   If you are having trouble connecting:
   • Make sure the logger is within range of your mobile device. The range for successful wireless communication is approximately 30.5 m (100 ft) with a full line of sight.
   • If your device can connect to the logger intermittently or loses its connection, move closer to the logger, within sight if possible.
   • Change the orientation of your phone or tablet to ensure the antenna in your device is pointed toward the logger. Obstacles between the antenna in the device and the logger may result in intermittent connections.
   • If the logger appears in the list, but you cannot connect to it, close the app, power down the mobile device, and then turn it back on. This forces the previous Bluetooth connection to close.

6. Deploy and start the logger. Place the logger in the location where you will be monitoring the temperature and humidity.
   Logging will begin based on the settings in the profile selected.
   Once logging begins, press the Next button on the logger to switch between the latest temperature and humidity readings, as well as the minimum and maximum values for both (see Minimum and Maximum Values for more details). See Downloading the Logger for details on how to access the logged data.

Logger Alarms

You can set up an alarm to trip on the logger when a temperature and/or humidity reading falls above or below a specified value. Specific alarm settings are set in the logger profile that you create in either InTemp Connect or in the app.

When an alarm trips:

• The logger LED will blink every 5 seconds.
• The alarm icon will appear on the LCD and in the app.
• If audible alarms are enabled in the logger profile, the logger will beep as follows every 15 seconds:
• One quick beep for temperature alarms.Two quick beeps for RH alarms.
• One long beep if multiple alarms were tripped at the same time.
• An Alarm Tripped event is logged.
  To mute a beeping alarm, press the Mute button on the logger. Once muted, you cannot turn the beeping back on. Download the logger to view details about the tripped alarm and to clear alarm indicators in the app and on the LCD.

Minimum and Maximum Values

The logger LCD displays the minimum and maximum temperature and humidity readings for the entire logging period. These values reset automatically when the logger is downloaded and restarted or stopped and reconfigured.
You can also clear these values as needed while the logger is logging by pressing both buttons on the logger simultaneously for 3 seconds until HOLD disappears on the LCD. Dashes (–) will then appear on the LCD for the minimum and maximum values until the next logging interval. The values will then continue to be updated for the remaining logging period or until they are cleared again. Note: This clears the data on the screen only. The actual logger and reporting data will not be cleared with this reset.

Passkey Protection
The logger is protected by an encrypted passkey automatically generated by the InTemp app for InTempConnect users and optionally available for local users who are using the app only. The passkey uses a proprietary encryption algorithm that changes with every connection.

InTempConnect Users,
Only InTempConnect users belonging to the same InTempConnect account can connect to a logger once it is configured. When an InTempConnect user first configures a logger, it is locked with an encrypted passkey that is automatically generated by the InTemp app. After the logger is configured, only active users associated with that account will be able to connect to it. If a user belongs to a different account, that user will not be able to connect to the logger with the app, which will display an invalid passkey message. Administrators or users with the required privileges can also view the passkey from the device configuration page in InTempConnect and share them if needed.

Local Users
If you are not using InTempConnect and instead of logging into the app as a local user, you can create an encrypted passkey for the logger that will be required if another phone or tablet attempts to connect to it. This is recommended to ensure that a deployed logger is not mistakenly stopped or purposely altered by others.

To set a passkey:

1. Tap the Devices icon and connect to the
2. Tap Set Logger
3. Type a passkey up to 10
4. Tap
5. Tap

Only the phone or tablet used to set the passkey can then connect to the logger without entering a passkey; all other mobile devices will be required to enter the passkey. For example, if you set the passkey for the logger with your tablet and then try to connect to the device later with your phone, you will be required to enter the passkey on the phone but not with your tablet. Similarly, if others attempt to connect to the logger with different devices, then they would also be required to enter the passkey. To reset a passkey, simultaneously press both the top and bottom buttons on the logger for 10 seconds, or connect to the logger in the app, tap Set Logger Passkey, and select Reset to Factory Default.

Downloading the Logger

You can download the logger to a phone or tablet and generate reports that include temperature and humidity readings, events, user activity, alarm information, and more. Reports can be shared immediately upon download or accessed later in the app.

**Deploying and Protecting the Logger

**

Use the four magnets on the back of the logger case to mount it to a magnetic surface.
The logger is designed for indoor use and can be permanently damaged by corrosion if it gets wet. Protect it from direct water contact. If the logger gets wet, remove the battery immediately and dry the circuit board.
Note: Static electricity may cause the logger to stop logging. The logger has been tested to 8 KV, but avoid electrostatic discharge by grounding yourself to protect the logger. For more information, search for “static discharge” on onsetcomp.com.

Battery Information

The logger requires two user-replaceable AAA 1.5 V alkaline or optional lithium batteries for operation at the extreme ends of the logger operating range. Expected battery life varies based on the ambient temperature where the logger is deployed, the frequency of connecting to the phone or tablet and downloading reports, the duration of audible alarms, and battery performance. New batteries typically last 1 year with logging intervals of 1 minute or greater. Deployments in extremely cold or hot temperatures or a logging interval faster than 1 minute can impact battery life. Estimates are not guaranteed due to uncertainties in initial battery conditions and the operating environment.
Note: Make sure the batteries installed have flat negative terminals. There should be no indent in the bottom of the batteries. Batteries with indents in the negative terminals may become loose and prevent proper operation.

To install or replace the batteries:

1. If the battery door is already installed on the back of the logger, use a Phillips-head screwdriver to remove
2. Remove any old
3. Insert two new batteries observing
4. Screw the battery door into

WARNING: Do not cut open, incinerate, heat above 85°C (185°F), or recharge lithium batteries. The batteries may explode if the logger is exposed to extreme heat or conditions that could damage or destroy the battery case. Do not dispose of the logger or batteries in a fire. Do not expose the contents of the batteries to water. Dispose of the batteries according to local regulations for lithium batteries.
