2. Physical Dimensions and Connector Pinout
This paragraph describes the process for installing the PROFIBUS Network Interface module in
a field device’s application hardware. The process is straightforward and consists of designing a
low-cost socket into the application hardware to provide signal interface and power connections.
Only a single +3.3V power supply is required. In addition, a UART or parallel interface is used
to communicate with a host processor.
Any unused module inputs may be left floating. The appropriate pull-up resistors are included
on the module.
2.1 Physical Constraints
The PROFIBUS Network Interface module is 2.485” (63,12mm) x 2.559” (64,99mm) as shown
in Figure 2. The module height from the X1 seating plane is 0.655” (16,63mm) as shown in
Figure 3. The DB9 connector, Hexadecimal address node switches, and all LEDs are
conveniently located along one edge of the PC board for easy access. Note that the DB9 is
extended past the edge of the board and the LEDs are flush with the PC board edge. The power
and bi-color LED indicators are on the bottom side of the PC board as shown in Figure 3.
All components on the bottom of the PC board are above the X1 connector seating plane, as
shown in Figure 3. All components on the application hardware that are within the PROFIBUS
Network Interface module outline should be shorter than the target system's X1 mating connector
to prevent physical interference. The recommended mating connector defined in the next
paragraph (SSW-116-21-F-D) has a height of 0.335” (8,51mm). If the recommended mating
connector is used, all components within the PROFIBUS Network Interface module outline
should be shorter than 0.335” (8,51mm).

2.2 Signal Interface Connector
The module is installed into the target system using a 64 pin, 0.1” (2,54mm) pitch socket. This
socket consists of 4 rows of 16 pins, as shown in Figure 4. The connector reference designator in
the PROFIBUS Network Interface module schematic is X1. The 4 rows are designated A, B, C
and D. Rows A and B are on 0.1” (2,54mm) centers, as are rows C and D. The connector can be
implemented by using 2 dual row connectors, 1 for rows A and B, and 1 for rows C and D. The
recommended connector for each of these is Samtec part number SSW-116-21-F-D. The
additional non-plated through hole shown in Figure 4 is a mounting hole. This non-plated
through hole is a 0.125” (3,175mm) hole.

2.4 Power requirements
The PROFIBUS Network Interface module consumes approximately 1.5W, supplied from a
single +3.3V supply. The power supply requirements for voltage and current are +3.3V ± 10%,
500mA. The 3.3V power is supplied to pins X1-B1 and X1-B9 and ground is connected to pins
X1-C1 and X1-C9.
Chassis ground is provided on the DB9 connector shield.
2.5 Reset Requirements
The PROFIBUS Network Interface module may be reset by the application hardware. Module
signal X1-B8, referred to as MAN_RESET_N is the reset input to the PROFIBUS Network
Interface module. This input is connected to the manual reset input of the on-board reset
supervisor (U3). U3 is an APX811-29UG-7 which requires a low pulse for a minimum of 10uS
in order to generate a valid reset.
Since the module does have an on-board supervisor IC, it may be allowed to initialize without an
external reset source. Module signal X1-B16, referred to as RESET_OUT_N, is an output that
indicates if the module is in a reset state. The signal will go low to indicate the reset state is
active.
Regardless of how the module is reset, it will not be available for communication until the
software has initialized the module and entered the operating state. The time required for the
module to enter the operating state is 1.0 second after the receipt of a valid reset pulse or after
power is valid if no external reset source is used.
3. Host Processor and PROFIBUS Network Interface Module
Communication Interfaces
3.1 UART Host Interface
The PROFIBUS Network Interface module requires a host processor, and may interface to the
host via a UART (serial) or a 16-bit parallel interface. Implementation of each of these interfaces
is described in the following paragraphs. The UART Host Interface is implemented using two
pins from the PROFIBUS Interface. These pins are X1-C3 and X1-C4. The signal names for
these pins, as shown in Table 3 are UIC1_16 and UIC1_0, respectively. UIC1_16 is the
PROFIBUS Interface TX signal, and UIC1_0 is the PROFIBUS Interface RX signal. The
PROFIBUS Interface TX signal must be connected to the Host Processor RX signal, and the
PROFIBUS Interface RX signal must be connected to the Host Processor TX signal. Figure 7
provides an overview of these signal connections.

Figure 7 – UART Host Interface Connection
3.2 Parallel Host Interface
The Parallel Host Interface is implemented as a 16-bit read FIFO and a 16-bit write FIFO. Some
support circuitry between the Host Processor and PROFIBUS Interface is required and must be
designed into the application hardware. The host processor connects to a 16-bit data bus and
must use 4 control signals to either read data from the PROFIBUS Interface or write data to the
PROFIBUS Interface. The PROFIBUS Interface connects to a 16-bit write data bus, a 16-bit
read data bus, and 5 control signals. Figure 8 provides an overview of these connections.

circuitry required for the Parallel Host Interface. Table 1 through Table 4 may be used
understand the signal names in the schematic. The 16-bit data bus on the host side of the
interface is referred to as HPI_D0 through HPI_D15. The four control signals are referred to as
HPI_OE_N, HPI_CS_N, HPI_WE_N, and FIFONOTEMPTY_N. As noted in the schematics, it
is important that signal pins X1-A9 and X1-A8 on the PROFIBUS Interface connector be tied
together when integrating the module on the application hardware.
Refer to the “Parallel Interface User Guide” for details regarding the software driver used by the
Parallel Host Interface. This document is provided on the USB flash drive included with the
evaluation kit, and it may be downloaded from the Developer Portal on the Innovasic website.
4. Considerations for Production and Maintenance
There are three methods for configuring and programming the PROFIBUS Network Interface during
production of end use systems. These methods are:
1. Bootloader
2. JTAG
3. Flash Programmer
The Bootloader and JTAG methods can also be used to perform field updates during maintenance for
the end devices. The subparagraphs below provide an overview of these methods. Figure 9 shows the
connections and devices involved for all three methods for either a module or embedded design.

UNCONTROLLED WHEN PRINTED OR COPIED 1-888-824-4184
4.1 Bootloader
Innovasic supports programming flash chips on the Network Interface modules or embedded
designs over the Network/Bus. The type of programming file used to support this is called a
.load file. Innovasic supplies .load files for each software component in the Network Interface.
These components are identified as:
Bootloader
Unified Interface
Network Application
Configuration Data
These .load file types are available in the Developer Portal on the Innovasic website, and can be
loaded as described in the “Bootloader User Guide.pdf”.
It is important to note that the BOOTLOADER_EN_N signal must be grounded when the
Network Interface powers up in order to enter the programming mode. This is an important
consideration if your final product requires field updates.
4.2 JTAG
Innovasic supports programming flash chips on the Network Interface modules or embedded
designs using the JTAG Connector. The type of programming file used to support this is called
an .elf file. Innovasic supplies .elf files for each software component in the Network Interface.
These components are identified as:
Bootloader
Unified Interface
Network Application
Configuration Data
These .elf file types are available in the Developer Portal on the Innovasic website.
Using the JTAG method for configuring and programing the Network Interface requires a PC,
JTAG “wiggler”, and programming software, and .elf programming files. The wiggler and
programming software may be ordered from Innovasic using part number
“RapID-PGMR VMCGR”.
A connector compatible with the ribbon-cable side of the wiggler is already installed on the
module. This connector must be used in the embedded design. The ribbon cable on the wiggler
connects to the module/embedded design connector. The other end of the wiggler connects to
the USB port of the PC. Detailed instructions for loading and programming with the .elf files are
provided with the JTAG programming software.

Note that it is possible to program blank flash using the JTAG method. This method is useful if
a Flash Programmer is not available. Access to the JTAG connector is required; however,
grounding BOOTLOADER_EN_N is not required.
4.3 Flash Programmer
Innovasic supports programming individual, blank flash chips using a flash programmer. The
type of programming file used to support this is called a Motorola S record file (.srec). Innovasic
supplies .srec files for each software component in the Network Interface. These components are
identified as:
Bootloader
Unified Interface
Network Application
Configuration Data
These .srec file types are available in the Developer Portal on the Innovasic website, and can be
sequentially loaded into the flash programmer. There is no need to be concerned the data will
overlap. Once the files are loaded into the programmer the complete executable package can be
programmed into the flash chip.
