nologies website.
By default, the Model 5401A’s management
Ethernet interface address configuration is
set for automatic. In this way, it will attempt
to automatically obtain an IP address and
associated settings using DHCP. If a DHCP
server is not detected an IP address will
automatically be assigned using the link-lo-
cal protocol in the IPv4 range of 169.254.0.1
to 169.254.255.254. There are two ways
that the management Ethernet IP address
and related network parameters can be set
to a manual (fixed or static) configuration.
The first method uses the front-panel display
and buttons to allow the management Eth-
ernet network parameters to be viewed and
revised as desired. An even easier method
might be to use the network configuration
webpage that is provided as part of the
Model 5401A’s management webpages.
Model 5401A Firmware
Update Procedure
It’s possible that updated versions of the
three firmware (embedded software) files
that are utilized by the Model 5401A’s
MCU (microcontroller) and two FPGA (field-
programmable-gate-array) integrated circuits
will be released to add features or correct
issues. Refer to the Studio Technologies’
website for the latest firmware files. The
Model 5401A has the ability to load appli-
cable firmware files into non-volatile memory
by way of a standard USB flash drive. The
Model 5401A implements a USB host func-
tion and provides access by way of a type
A receptacle located on the back panel.
The Model 5401A updates its firmware us-
ing three files. The Main MCU firmware is
named M5401A.bin, the Main FPGA firm-
ware is named DSMC.bit, and the Sync
FPGA firmware is named CLOK.bit.
The update process begins by preparing
a USB flash drive. The flash drive doesn’t
have to be empty (blank) but must be in the
personal-computer-standard FAT32 for-
mat. One, two, or all three of the firmware
files can be automatically loaded at essen-
tially the same time. On the flash drive’s
root folder, save the desired new firmware
files, ensuring that the required names are
specified. The file name for the Main MCU
firmware must be M5401A.bin. The file
name for the Main FPGA firmware must be
DSMC.bit. And the file name for the Sync
FPGA firmware must be CLOK.bit. Be
certain to use the eject command to ensure
that the file is correctly stored on the USB
flash drive.
Studio Technologies will supply each firm
-
ware file inside a .zip archive file. While the
firmware file inside of the zip file will adhere
to the naming convention required by the
Model 5401A, the name of the zip file itself
will include the file’s version number. For ex-
ample, a zip file named M5401Av1r04MCU.
zip would indicate that version 1.04 of the
Main MCU firmware (M5401A.bin) is con-
tained within this zip file.
Once the prepared USB flash drive is in-
serted into the USB receptacle, located on
the Model 5401A’s back panel, the Model
5401A must be powered off and then pow-
ered on again. At this point the file(s) stored
on the USB flash drive will automatically
load. The precise steps required will be
highlighted in the following paragraphs.
To install one, two, or all three of the firm
-
ware files follow these steps:
1. Remove power from the Model 5401A.
This will entail removing the AC mains
power connector or removing the con-
nector associated with the external
source of nominal 12 volts DC. (Both
must be disconnected if dual powering
has been implemented.)
