Getting Started

Introduction
Thank you for your purchase of the YELLOW JACKET® YJACK™ Series of Bluetooth® Sensing devices. The YJACK™ series of devices are the next evolution in creating an interconnected and efficient work environment allowing service technicians to work  more quickly and precisely in the ever growing and complicated HVAC/R industry.
Take a moment to familiarize yourself with your new device(s). You will notice that all YJACK™ devices feature a simple on/off button to power cycle the device, a quick-coupler for system attachment and/or a mounting magnet for strategic placement on  surrounding metallic surfaces, and flexible connections to aid in the proper positioning of the device within your workspace. Each YJACK™ product is powered by (2) AAA batteries housed beneath the removable battery door on the back of the device. The procedure to replace the product batteries is the same across all YJACK™ devices and will be covered in more detail later.
All YJACK™ products include an integrated Electronic Paper Display (EPD) or a status indication LED adjacent to the power button which can provide feedback as to the device’s current mode of operation. During normal operation, the status indicator LED will  flash yellow once every two seconds to indicate that a measurement has been transmitted via Bluetooth®.
Unlike other Bluetooth® devices, YJACK™ devices do not require “pairing” or an established connection between one another or the user’s smart device to transmit and receive information. Simply power the device on and it will immediately begin broadcasting  data to other available devices within the broadcast range.

YJACK™ tools may be used individually or together, broadcasting up to (6) unique measurements to one P51-870 TITAN® Digital Manifold (see firmware requirements) or an unlimited number of unique measurements to a smart device running the YJACK  VIEW™ smart application.

Using your YJACK™ Devices

Powering the device on
All YJACK™ devices utilize the same power switch and either an integrated display or a status indicator LED. Press and hold the power button to power on the device. Release the power button when the display image changes or the status indicator LED  illuminates.

When using the YJACK PATH™, numeric LEDs 1-8 will illuminate to indicate the number of YJACK™ and P51-870 TITAN® devices within range.

Placing the Device on the System

YJACK™ Temperature Clamp

Depress the clamp handle to open the clamp jaws and attach the clamp to the pipe surface where temperature measurements are desired. For best results, attach the clamp in an area where the clamp jaws have full engagement of the pipe surface.
The clamp can  be used on pipes up to 1.25 inches in diameter. Avoid clamping over areas of pipe that are coated or insulated as this may impact the accuracy of the system temperature reading. If there is a ferrous metal surface near the placement of the clamp, the magnet on  the bottom of the radio module can be attached to the surface for a more secure connection.

YJACK™ Temperature Strap

Utilize the flexible strap to tightly secure the strap clamp to the pipe surface where temperature measurements are desired. First, open one of the buckles and pull the strap out of the buckle so that it is only retained in the second buckle. Feed the strap around  the pipe and back through the open buckle. Pull the strap tightly around the pipe and then close the buckle. The strap can be used on pipes up to 6 inches in diameter. For best results, attach the strap in an area where the strap body has full engagement of the pipe surface. Avoid attaching the strap over areas of pipe that are coated or insulated as this may impact the accuracy of the system temperature reading. If there is a ferrous metal surface near the placement of the clamp, the magnet on the bottom of the radio  module can be attached to the surface for a more secure connection.

YJACK DEW™ Psychrometer

Remove the black vinyl cap covering the sensing element. Form the flexible wand to the desired shape and place the sensing element within the ventilation system or wherever psychrometric data is desired. If there is a ferrous metal surface near the placement of  the Dew, the magnet on the bottom of the radio module can be attached to the surface for a more secure connection.

YJACK PRESS™ Wireless Pressure Gauge

Remove the red plug from the brass quick coupler nut. Make sure the pressure transducer has been zeroed (this will be covered in more detail later) and attach the device directly to the system low-side or high-side service port. A 5/16” adapter (19121 straight or  19221 90 degree) can be used for systems with 5/16” connections. The integrated charging port on the back of the device can be connected to a charging hose for adjustment of system charge while continuing to monitor system pressure.

YJACK VAC™ Wireless Vacuum Gauge

Remove the red plug from the brass quick coupler nut. Then the device can be attached directly to the side port of a core removal tool or to a system service port. A 5/16” adapter (19121 straight or 19221 90 degree) can be used for systems with 5/16” connections.  For the most accurate system vacuum readings and to avoid contamination of the sensor, it is not recommended to connect the vacuum gauge directly to the vacuum pump.

YJACK AMP™ Wireless Current Probe

Depress the clamp lever and place the CT around the hot or neutral wire where AC current is to be measured. Make sure the clamp jaws are fully closed for best accuracy. If there is a ferrous metal surface near the placement of the clamp, the magnet on the  bottom of the radio module can be attached to the surface for a more secure connection.

YJACK MANO™ Wireless Dual Port Manometer

Make sure that the supply and return pressures have been zeroed (this will be covered in more detail later). For static pressure measurements in ducting, drill 3/8” holes where the static pressure tips are to be placed. Insert the static pressure tips into the  ductwork so that the tips are pointing towards the direction of airflow and use the provided tubing to connect the corresponding pressure tips to the supply and return pressure ports on the device. For gas pressure measurements, use the appropriate gas  manifold fitting and use the provided tubing to connect the fitting to the corresponding pressure port on the device.

YJACK PATH™
Although the YJACK PATH™ is not placed directly on the system, the location of the device can impact its effectiveness in repeating the Bluetooth® signals from the other YJACK™ devices. Be mindful of the environment in which readings are being taken. If  there are obstructions, such as walls, paneling, or other equipment between the YJACK™ devices and the P51-870 TITAN® or smart device running the YJACK VIEW™ app, placing the YJACK PATH™ in an area that has direct line-of-sight of the Bluetooth® devices often provides the best results and longest communication ranges. Also keep in mind that there could be obstructions and interference caused by signals not visible. If you believe that you may be experiencing signal interferences, move the YJACK  PATH™ to a different location until the Bluetooth signal improves. If there is a ferrous metal surface near the placement of the YJACK PATH™, the magnet on the bottom of the radio module can be attached to the surface for a more secure connection.

Status LED: what does it mean?

When powering on the YJACK™ device, hold the power button until the status LED illuminates solid yellow, then release the power button. Once powered on, the LED will flash every time the YJACK™ devices readings are broadcast, every 2 seconds. When the  battery level reaches 10%, the LED will flash red to indicate the low battery condition. When powering off the device, the LED stays red until the power button is released and the device is powered down.

With a P51-870 TITAN® Digital Manifold

To use the YJACK™ series of Bluetooth® Sensing devices with the P51-870 TITAN® Digital Manifold, ensure that the P51-870 TITAN® firmware version is up to date. Version 2.01 or higher is required to display information from the YJACK™ Temperature  Clamp/Strap and YJACK DEW™. Version 3.0 and higher (both board and radio firmware) is required to display information from the YJACK™ VAC and YJACK AMP™. The YJACK PRESS™ and YJACK MANO™ readings are only broadcast to the YJACK VIEW™ app and cannot be displayed on the P51-870 TITAN®. To check the firmware version, access the general settings screen on the P51-870 TITAN® by pressing the “gear” icon in the upper right-hand corner of the display and confirm the board and radio  firmware versions. If a firmware update is required, reference the “P51-870 TITAN® Digital Manifold – Firmware Update” section below for details on updating the firmware.

When a compatible YJACK™ device is turned on and within range of the P51-870 TITAN®, a message will appear in the upper left corner of the display, indicating that the P51-870 TITAN® has discovered a YJACK™ device. For display of YJACK™ Temperature Clamp and Strap probes within the Pressure/Temperature session, press on the gray box containing the temperature measurements. A list of available temperature measurement devices will appear and the YJACK™ Temperature Clamp and Strap probes can be selected along with any wired temperature probes plugged into the P51-870 TITAN®. This can be done for both the lowside and high-side temperature readings. Pressing in the center of the low-side and high-side pressure gauges changes the display of the pressure and temperature readings into a line graph format. Pressing on the pressure/temperature line graphs changes the display to show psychrometric readings from the YJACK DEW™ probes. The readings can be assigned by pressing in the gray area below the line graphs. A list of available YJACK DEW™ probes will appear. The left slide of the display which previously contained the low- side system measurements is now the supply air side and the right side of the display is the return air. The P51-870 TITAN®

graphs the supply and return air relative humidity and dry bulb temperatures. Below the graphs are the numeric values of the relative humidity and dry bulb temperatures, along with the wet bulb temperature and dew point. To go back to pressure readings, press on the line graphs and the analog pressure gauge will appear. There is not a unique session to display readings from the YJACK AMP™, but the readings can be viewed from the reading assignment screens within the Pressure/Temperature session and data  from the YJACK AMP™ and other P51compatible  YJACK™ devices that are within range will automatically be logged to the P51 manifold’s internal memory.

Troubleshooting & FAQs

Q: Why am I losing my Bluetooth® connection when I am within 400’ of the YJACK™ device(s)?

A: With any radio technology, when you start to add obstructions between the transmitter and the receiver, the ultimate range may decrease as different objects interfere with the radio signal in different ways. The more obstructions you add between YJACK™ device and either the P51-870 TITAN® or the smart device running the YJACK VIEW™ app, the weaker the signal may become after it has passed through or around the obstacles. This could ultimately lead to a shorter maximum range, but this can be improved by using the YJACK PATH™ signal repeater device. All YJACK™ devices, including the YJACK PATH™, utilize a Bluetooth® 4.2 compliant low energy radio to ensure the best possible range, however each situation will be slightly different depending on the environment/ surroundings within you are working. The YJACK PATH™ can be positioned to get around obstructions and up to 6 YJACK PATH™ devices can be used simultaneously to maximize the connection range, even in environments with multiple obstructions.
