of third parties by or arising from the use of PoLabs products or technical information described in this document.
No license, express, implied or otherwise, is granted hereby under any patents, copyrights or other intellectual
property rights of PoLabs or others. PoLabs claims the copyright of, and retains the rights to, all material
(software, documents, etc.) contained in this release. You may copy and distribute the entire release in its original
state, but must not copy individual items within the release other than for backup purposes.
Descriptions of circuits, software and other related information in this document are provided only to illustrate
the operation of the products and application examples. You are fully responsible for the incorporation of these
circuits, software, and information in the design of your equipment. PoLabs assumes no responsibility for any
losses incurred by you or third parties arising from the use of these circuits, software, or information.
PoLabs has used reasonable care in preparing the information included in this document, but PoLabs does not
warrant that such information is error free. PoLabs assumes no liability whatsoever for any damages incurred by
you resulting from errors in or omissions from the information included herein.
PoLabs devices may be used in equipment that does not impose a threat to human life in case of the
malfunctioning, such as: computer interfaces, office equipment, communications equipment, test and
measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal
electronic equipment, and industrial robots.
Measures such as fail-safe function and redundant design should be taken to ensure reliability and safety when
PoLabs devices are used for or in connection with equipment that requires higher reliability, for example: traffic
control systems, anti-disaster systems, anticrime systems, safety equipment, medical equipment not specifically
designed for life support, and other similar applications.
PoLabs devices shall not be used for or in connection with equipment that requires an extremely high level of
reliability and safety, as for example: aircraft systems, aerospace equipment, nuclear reactor control systems,
medical equipment or systems for life support (e.g. artificial life support devices or systems), and any other
applications or purposes that pose a direct threat to human life.
You should use the PoLabs products described in this document within the range specified by PoLabs, especially
with respect to the maximum rating, operating supply voltage range and other product characteristics. PoLabs
shall have no liability for malfunctions or damages arising out of the use of PoLabs products beyond such specified
ranges.
Although PoLabs endeavors to improve the quality and reliability of its products, semiconductor products have
specific characteristics such as the occurrence of failure at a certain rate and malfunctions under certain use
conditions. Further, PoLabs products are not subject to radiation resistance design. Please be sure to implement
safety measures to guard them against the possibility of physical injury, and injury or damage caused by fire in the
event of the failure of a PoLabs product, such as safety design for hardware and software including but not
limited to redundancy, fire control and malfunction prevention, appropriate treatment for aging degradation or
any other appropriate measures.
Usage: the software in this release is for use only with PoLabs products or with data collected using PoLabs
products.
Fitness for purpose: no two applications are the same, so PoLabs cannot guarantee that its equipment or
software is suitable for a given application. It is therefore the user's responsibility to ensure that the product is
suitable for the user's application.
Viruses: this software was continuously monitored for viruses during production; however the user is responsible
for virus checking the software once it is installed.
Upgrades: we provide upgrades, free of charge, from our web site at www.poscope.com. We reserve the right to
charge for updates or replacements sent out on physical media.
Please contact a PoLabs support for details as to environmental matters such as the environmental compatibility
of each PoLabs product. Please use PoLabs products in compliance with all applicable laws and regulations that
regulate the inclusion or use of controlled substances, including without limitation, the EU RoHS Directive. PoLabs
assumes no liability for damages or losses occurring as a result of your noncompliance with applicable laws and
regulations.
Please contact a PoLabs support at [email protected] if you have any questions regarding the information
contained in this document or PoLabs products, or if you have any other inquiries.
The licensee agrees to allow access to this software only to persons who have been informed of and agree to
abide by these conditions.

2. Technical specifications
Schematics of PoExtension device is as following. It is intended for use only by experienced electrical
engineers, as PoLabs will not support custom slave devices. Custom slave devices must follow the
exact schematic to be compatible. Note that the schematic is not complete.
PoLabs develops general purpose PoExtension devices, as well as custom devices on customer
request (in bigger quantities) which are compatible with PoKeys master devices (56U or 57E).

3. PoExtBusOC16-CNC
Overview
PoExtBusOC16-CNC uses 6 pins from the PoExtension connector. Table under Installation shows
connections to PoKeys master devices. PoExtBusOC16-CNC allows you to connect up to 8 stepper
motor drivers. Please use CNC version only with stepper motor drivers. If you wish to expand the
number of outputs on your PoKeys device please use PoExtBusOC16 (non CNC version) or
PoExtBusRe.
Only one PoExtBusOC16-CNC can be used, daisy-chaining is not supported.
Features
-
Up to 8 stepper motor drivers can be connected
Enable signal for each driver
PoExtension connector for connecting to master device
Only one PoExtBusOC16-CNC can be used
