2.3 Board application
The board enables the application design of a speed controlled closed-loop
motor control drive profile synchronized over a Real-time Ethernet based
industrial commination protocol. It serves as example for an FOC based
motor control system design with network connectivity using the netX 90
multiprotocol SoC with built-in motor control features.
The motor supply voltage is at the same the power supply for the NXHX 90-
MC board. The integrated DC/DC converter of the 3-Phase Gate Driver IC,
with a wide voltage input range from 12V to 43V (36V +20%), generates the
3.3V single supply for the netX 90. For operating the NXHX 90-MC board,
the nominal input voltage range is +12V to 36V DC for either 12V, 24V or
36V motor supply voltages with 24V the most popular for industrial
applications.
Figure2: NXHX 90-MC board with NXHX-DH adapter
In order to facilitate the interconnection of industrial motors with integrated
quadrature encoders, Hilscher offers an NXHX-DH adapter accessory card
for the NXHX 90-MC board. It contains push-in connectors for up to two
quadrature encoders and three digital hall sensors. The NXHX-DH board
converts RS-422 (5V differential) and TTL (5V single-ended) quadrature
encoder signals to 3.3V inputs for the NXHX 90-MC board and provides a
5V supply for the encoders. Additionally, it contains analog filters for the
digital hall inputs.

2.5 Operating elements
2.5.1 S400 – Slide switches for console mode and alternative boot mode
For identifying the switches on the board, see position (2) in section
Positions of interfaces and operating elements [}page8].
Standard boot mode
In standard boot mode, the ROM code searches for a valid firmware and
– if available – starts it. If the ROM code cannot find a valid “regular”
firmware, it tries to start a valid “maintenance” firmware instead. If neither
“regular” nor “maintenance” firmware is found, the ROM code automatically
enters console mode.
S400 settings for standard boot mode:
Switch 5 = OFF
Switch 6 = OFF
Console mode
The ROM code of the netX 90 features a console mode that enables the
handling of firmware programming depending on the selected console
mode interface, e.g. via UART, via Ethernet, etc. Thus you can download a
firmware file to the flash memory of the device, e.g. from your development
PC by using the “flasher tool” of netX Studio CDT.
Note:
Note that downloading a firmware to the netX 90 is also possible via
the JTAG interface. You can use the on-board JTAG-to-USB
connection, as described in the Getting started: netX Studio CDT –
netX 90 development, DOC170504GSxxEN, (in chapter How to ...
Use the Flasher tool).
S400 settings for console mode:
Switch 5 = ON
Switch 6 = OFF or ON

Descriptions 11/83
Alternative boot mode
In alternative boot mode, the ROM code starts the “maintenance”
firmware instead of the “regular” firmware. The maintenance firmware is
capable of programming a new firmware (firmware update).
Potential use cases are:
·Firmware update procedures:
A new firmware received via web server or host interface is stored
either on-chip in INTFLASH1 or off-chip in an externally connected SQI
Flash. A software reset cycle initiated by a software command or a
hardware reset cycle (by S401 reset button or power-on) while switch 6
is at ON position starts a maintenance firmware, which programs the
new firmware.
·Multiple firmware versions:
The netX 90 has a maintenance firmware stored in INTFLASH1 and
holds multiple firmware versions for different Real-Time Ethernet
protocols in an externally connected SQI Flash. The maintenance
firmware programs the firmware selected by the system integrator, e.g.
via a rotary DIP-switch (or other ways).
Note:
If console mode and alternative boot mode are both enabled (i.e. if
switch 5 and 6 are both in ON position), the console mode always
has priority over the alternative boot mode.
If e.g. a power loss disrupts the programming of the new firmware,
the ROM code detects that the procedure is incomplete and re-
starts the maintenance firmware without prior selection.
S400 settings for alternative boot mode:
Switch 5 = OFF
Switch 6 = ON

2.6.5 X901 – Sensor connector for NXHX-ENC and standard MMIOs
MMIO pin header connector X901 for the NXHX-ENC (part number
7924.000).
This connector can also be used as interface for standard MMIO, BiSS and
EnDat signals, and for connecting UART (NXHX-RS232 adapter module)
and CAN (NXHX-CO adapter module) peripherals to the application CPU of
the netX 90.
For identifying the connector on the board, see position (8) in section
Positions of interfaces and operating elements [}page8].

2.6.6 X902 – Connector for NXHX-RS232 adapter module (UART)
Pin header connector X902 for the serial NXHX-RS232 adapter module
(part number 7923.010). For identifying the connector on the board, see
position (7) in section Positions of interfaces and operating
elements [}page8].
To enable a UART connection to your development PC via the NXHX-
RS232 module mounted onto this interface, put switch 2 of S701 into ON
position (see section S701 – Slide switches for selecting JTAG, UART,
ADCs and user LEDs [}page14]).
By using the UART console mode, you can e.g. download a firmware file to
the internal flash memory of the netX 90 SoC.

2.6.7 X1000 – Mini-B USB connector
The Mini-B USB connector X1000 is the FTDI JTAG-to-USB debug
interface. It can also be used as UART interface for diagnosis and firmware
download. For identifying the connector on the board, see position (24) in
section Positions of interfaces and operating elements [}page8].
Note:
To enable the USB connector as JTAG interface, put switch 1 of
S701 into OFF position. To enable the USB connector as UART
interface, put switch 2 of S701 into OFF position (for location of
S701, see position (6) in section Positions of interfaces and
operating elements [}page8]).
