The HTT-B2EX-BATT is a battery-powered, 2-button, wireless keypad 

designed to control a wide range of applications supported by a 

Crestron

®

 control system. Compact and simplistic in design, the 

HTT-B2EX-BATT is an ideal tabletop keypad for use as a hotel bedside 

controller, a conference room presenter selector or a simple living 

room lighting/shade controller. The HTT-B2EX-BATT is powered by 

lithium coin cell batteries that boast high performance and a long 

battery life. Outfitted with Crestron infiNET EX

®

 technology, the 

HTT-B2EX-BATT can be wirelessly connected to a Crestron control 

system.
The HTT-B2EX-BATT is available with an optional tether that allows 

the device to be secured at its mounting location.
infiNET EX Communication
Built on steadfast infiNET™ technology, infiNET EX is the new 

standard in 2-way wireless connectivity that can handle installations in 

even the most urban settings. The redundant nature of its mesh 

networking technology means that a command will never be missed, 

resulting in faultless operation—something that is of the utmost 

importance when it comes to home automation. The HTT-B2EX-BATT 

harnesses this cutting edge wireless connectivity which affords it a 

level of robustness and dependability above other solutions.

Installation of the HTT-B2EX-BATT is limited to powering the device, 

placing it on a flat surface and securing it to the line cord of a lamp 

(optional).
Power Device
The HTT-B2EX-BATT is shipped with the batteries pre-installed. To power 

the device pull and remove the plastic tab on the side of the device. Once 

the plastic tab is removed the device is powered and ready to be operated. 

Properly discard the plastic tab.
Place Device 
Place the HTT-B2EX-BATT on the table surface where it is to be used.
Secure Device (Optional)

A security tether is available on the HTT-B2EX-BATT-B-T W/TETHER and 

HTT-B2EX-BATT-W-T W/TETHER. The tether is secured inside the cover 

of the keypad and attaches to a lamp cord. Use the following steps to 

secure the loose end of the tether to a lamp cord.

1.  Wrap the loose end of the tether around the lamp cord. The loop 

should be loose enough to allow the tether to slide along the lamp 

cord but not loose enough to slide it over the plug.

2.  Use the supplied metal crimp and a pair of pliers to secure the tether 

to the lamp cord.

3.  Neatly trim the excess wire from the tether using a pair of wire cutters.

It is recommended to use Crestron Toolbox™ to set the RF ID of the 

device while the device is awake. Wake the device by pressing the large 

or small button on the HTT-B2EX-BATT.
The RF ID of the unit, set using Crestron Toolbox, must match the RF ID 

specified in the Crestron Studio™ or SIMPL Windows program.

The device connects to the Crestron network via the infiNET EX 

communications protocol. Use the procedures outlined below to join 

or leave an infiNET EX network and to verify communications 

between the device and the control system.
Joining an infiNET EX Network
Before a device can be used in a lighting system, it must first join an 

infiNET EX network by being acquired by an infiNET EX gateway.

NOTE:  A device can be acquired by only one gateway.

1.  Put the infiNET EX gateway into Acquire mode from the unit 

itself or from Crestron Toolbox, as described in the latest version 

of its manual, which is available from the Crestron Web site 

(www.crestron.com/manuals).

NOTE:  In an environment where multiple gateways are 

installed, only one gateway should be in Acquire mode at any 

time.

To upgrade the firmware on the HTT-B2EX-BATT use Crestron 

Toolbox (v. 2.37.01 or later). Upload firmware with the infiNET EX 

Firmware Upload tool by clicking 

Tools | infiNET EX Firmware 

Upload in Crestron Toolbox.

NOTE:  This infiNET EX Firmware Upload tool eliminates the need 

for the user to manually wake every sensor that is being updated.
NOTE:  When using the infiNET EX Firmware Upload tool, the 

device does not update immediately. It updates upon waking up 

and communicating with the gateway. 

The infiNET EX Firmware Upload tool has four columns: product ID, 

Firmware image, model name, and version number. Assign the 

selected firmware image from the bottom box to the corresponding 

ID/model name. 
After pressing the load firmware file button, the gateway holds the 

file and waits for the device to wake up on its own. Once the device 

wakes up it checks for differences in the firmware file, if different 

than the one currently on the device the firmware is loaded onto the 

sensor.
