Question 3

Handling the X-Headstage [Important]

Accepted Answer

Properly handle the X-Headstage will prolong the lifetime and reliability.

To plugin connect the EIB/Probe/Adapter, align the two units directly on top of each other and exert equal force along the entire area. If the connectors are plugged in properly, there will be a satisfying lock feel. Make sure a good connection is established before screwing the X-Headstage with standard armor into an adapter.

To detach the EIB/adapter from the headstage, use a small flat screwdriver and tilt the EIB or probe boards away from the X-Headstage from either the top (HDMI or Omnetics connector) or bottom side. Do not push the EIB/probe along the side (the long side).

To plugin the cable, exert some press over the HDMI/Omnetics connector to minimize any tear between the stacks of PCBs in the X-Headstage. This is particularly important for X-Headstage without armor protection.

Question 4

How is XDAQ different than Open-Ephys Acquisition system?

Accepted Answer

OpenEphys acquisition box offers a great value and highly capable software that is used by many researchers around the world.

KonteX designed the XDAQ to support the multi-modal experimental needs in today's neuroscience. Every XDAQ features both electrical stimulation and high quality neural recording out of box. KonteX carefully tuned the electrical performance and characteristics of the XDAQ line and uses aluminum enclosure for higher durability and heat management. XDAQ One and AIO offers improved performance with TruGround and electrically isolated animal ports. XDAQ AIO supports even more functionalities in optogenetics, behavior video recording, and calcium imaging.

XDAQ Core is priced competitively as the OpenEphys acquisition box but offers improved electrical performance and additional functionality for electrical stimulation. For those looking for a solution that supports more experimental needs and that can be scaled as research need arises, XDAQ AIO is an excellent choice. Note that AIO functionalities can be added after base system is purchased.

Question 5

What options do I have to power the XDAQ?

Accepted Answer

XDAQ Core is powered by 35W USB-C PD (required power spec: 12V 3A). Note that some power brick have limited driving capability and causing the XDAQ unable to lock in the power (you will hear repeated clicking sound). In this case, you will need to try a different make/model.

XDAQ One and AIO can be powered by the same external 35W USB-C PD adapter or directly to wall plug (AC input 100-240V). If both USB-C power and AC wall supply are active, USB-C circuit will be disabled. Please make sure the GND pin in the wall plug is truly grounded to earth.

If desired, you can also run XDAQ off batteries. There are many USB PD based power banks; be sure to check that it supplies the required 12V 3A spec.

Question 6

How do I attach/detach the adaptor to the X-Headstage?
