Electrical Integration
2.1
Overview
This section provides information and guidelines for designing the electrical aspects of a solution that
incorporates mDynamo Weatherized. MagTek strongly recommends vetting and testing solution designs
before finalizing and deploying them, to make sure the design meets all requirements (e.g., functional,
legal, security, certification, safety, and so on). When designing a solution that incorporates mDynamo
Weatherized, consider the following:
•
Review section 1.4 mDynamo Weatherized Major Components for an overall introduction to the
device's physical features and what they are called.
•
Review Appendix A Technical Specifications to make sure the device is suitable for the solution.
•
Review safe handling practices in section 1.7 Handling to make sure the logistical aspects of the
solution design meet the device's handling requirements.
•
Develop solution-specific installation procedures and training materials before distribution to
installation technicians.
•
Review section 5 Maintenance and develop a maintenance procedure and schedule. When installed
in the solution-specific enclosure, the device may require additional maintenance not covered in the
general guidelines provided here.
•
Review any additional requirements from other agencies, such as PCI certification requirements,
building codes, and so on, which may introduce additional constraints to the solution design.
2.2
Connectors
mDynamo Weatherized provides the following connections (see Figure 1-2).
•
A USB Device port, labeled
USB port, or connected to the host via a powered USB hub, to provide power to the device and
bidirectional communication with the host. The device's USB connector is a Micro-USB B
receptacle designed to mate with a standard Micro-USB B connector found on the peripheral end of
commercially available cables. MagTek does not support connecting multiple mDynamo
Weatherized devices simultaneously to the same host. Depending on usage, the device expects to
draw up to 500mA at 5V from the USB port, and the solution design must ensure 500mA is available
to the device at all times. The mDynamo controller board in mDynamo Weatherized draws a
maximum of 300mA, and draws additional current to drive devices connected to the RS-232 port and
the Auxiliary SPI port.
•
An Auxiliary SPI port, labeled
Molex Pico Blade header designed to mate with Molex PicoBlade connector 51021-1000. The dot
on the printed circuit board indicates pin 1. Depending on usage, the auxiliary SPI port can provide
up to 100mA @ 3.3V to power an external SPI device.
•
An RS-232 port labeled
USB. The RS- 232 port can be directly connected to a host's fully powered RS-232 port to provide
power to the device and bidirectional communication with the host. It is a 10-pin 1.25mm pitch
Molex PicoBlade header designed to mate with Molex PicoBlade connector 51021-1000. The dot on
the printed circuit board indicates pin 1.
•
An LED connector, labeled
integrated into the device's bezel. It is a 4-pin 1.25mm pitch Molex PicoBlade header designed to
mate with Molex PicoBlade connector 51021-0410. The dot printed on the circuit board indicates
pin 1. The connector provides 3.3V up to 24 mA. The device can be configured to drive
