Introduction
The Holt Mini PCIe reference design features one or two Holt HI-2130 MIL-STD 1553 multi-channel dual
redundant terminals with integrated transformers on a single size F2 Mini PCIe card. The card is designed
to operate in a PC or Single Board Computer with accessible Mini PCIe slots running under Windows 10 or
Linux. This demonstration release focuses on Windows 10. The demonstration software uses the Holt API
Library functions, providing an abstraction layer that greatly simplifies host programming. A console menu
is presented in a Windows Command Shell window where commands are executed.
This Technical Manual covers the hardware, software and instructions for how to transfer the Holt Flash
Drive (FD) files to the user’s PC. See the Quick Start Guide (QSG-2130mPCIe_Win10) for an introduction
to the card, Application Development Kit (ADK) contents and how to run the demonstration software. Use
the instructions in this guide to download/ install the Holt software and Microsoft Visual Studio 2019 IDE
tool used for software development onto a user’s PC.

Hardware Description
The Holt Mini PCIe card features two Holt HI-2130 dual-redundant multi-terminals on a 50.95mm x
30mm form factor per the PCI Express Mini Card Electromechanical Specification (See below). A Xilinx
XC7A12T FPGA serves as the interface between two HI-2130s and the PCIe Gen2 bus. The host
communicates with the card using the built-in PCIe drivers once a PCIe link is established after power
up. The card does not support PCIe low power modes using dynamic clocking, pin-7 CLKREQ# is
grounded on the card.

Break Out Board
The Break Out board connects to the PCIe card through a ribbon cable and is used to break out both
BusA and BusB connections from both channels (Dev0 and Dev1). The Transmit Inhibits inputs are pulled
high which present a low to the HI-2130 devices which enables 1553 bus transmissions by default. Table
8 is a list of the signals and descriptions on the inter-connect ribbon J4 connector. For board component
locations, connectors, IC’s and test points, see Figure 5 –Board References at the end of the document.
Two break-out boards are available.
Single channel: mPCIe_breakout-1F
Dual channel: mPCIe_breakout-2F

First Things First
All software and documents are provided in a ZIP file in the provided USB flash memory stick. This unzips
into a directory named MiniPCIeDual2130Win10. When this Technical Manual uses the phrase “top-
level”, it should be inferred that this means inside the MiniPCIeDual2130Win10 directory. In this
distribution, inside the top-level directory, a Projects folder contains the named Visual Studio projects.
They can reside anywhere in a file-system that is read-writeable. Our convention typically is that
“Projects” is in our home folder for ease of access such as “C:/Users/name/MiniPCIeDual2130Win10”.
Installing this project under “My Documents” may cause some files to be Read Only and prevent
successful building of the projects.
The distribution is released in a Win Archive file (MiniPCIeDual2130Win10.zip) which needs to be
unzipped. It contains the following top-level hierarchy:
Note: Filenames and dates may appear different

Reviewing the QSG-2130mPCIe_Win10 document prior to reading this document is highly
recommended. In order to successfully execute the Holt demo program, the PC must be able to detect
the card’s PCIe interface at power up. This section details the procedure to install the hardware, driver
and run an initial test to ensure that the driver is fully functional under Windows 10.
Note: you will need administrator capability for this system in order to complete this procedure since
you will be updating the windows drivers.
Note to customers who installed the Beta Release 1.0 distribution from Holt IC: Please see the QSG-
2130mPCIe_Win10 document for the procedure to uninstall the Beta release before you execute this
installation.
Mini PCIe Card Installation
1. You should be comfortable using the Windows 10 Device Manager interface and the Windows
Command shell.
2. Instruct Windows to shut down and then (once shutdown) either physically turn off the power on
your system’s power supply or physically disconnect the power cord to the system’s power
supply(s). The reason for this is that some systems leave residual power to various components
even when shutdown. It’s always good practice to ensure that the power is disconnected after
shutdown if you are inserting or removing internal hardware.
3. Install the Holt Mini PCIe card using standard ESD safe handling practices (e.g. ground strap, static
limiting work-area…)
4. Insert the EV-2130mPCIe-1F/2F board(s) into the Mini PCIe slot(s) on your system’s motherboard.
If you are using Mini PCIe-to-PCIe X1 adapter boards, mount the EV-2130mPCIe-1F/2F card into
the adapter board and insert it into a PCIe X1 slot. Carefully insert the small ribbon cable to the
Mini Card J4 connector and the other end to the Break Out board on the EV-2130mPCIe-1F/2F
cards. The cable is fine pitched and the connector plastic fasteners are delicate so care must be
exercised to avoid damaging the connector.
5. Power on the system and login as normal.
6. Power up the PC. Shortly after powering up the computer, the green PCIe Link LED 8 should be
on and the Heart Beat LED 9 should flash on and off on your [1F] or [2F] cards.
7. When LED 8 illuminates, the computer boot-up sequence has detected the PCIe link on the card.

8. However, the computer may not properly detect the Holt device until the Mini PCIe Windows
Driver is installed.
Software Installation
This release includes two software installers: one for the Driver software, and one for the Demo+Libs.
We’ll perform the driver installation first.
Driver Installation
The top level directory of the release kit has a directory called driver_installer which includes the
holt_pcie.exe driver installer. At this time, Holt is not releasing the source code to the driver, but this
structure is identical to our build procedure. In this step, we’ll install the Holt Windows driver. But first
let’s make sure Windows detects the new hardware.
1 . Start the Windows Control Panel and Click on Device Manager. In the Action tab, select “Scan for
hardware changes”;
