Matched differential traces length
High performance signal integrity traces from K-connectors to SFP-DD host connector
I2C master driven from both on board microcontroller or external pin headers
On-board LEDs display MSA output alarm states
On-board pin headers for MSA low speed signals external control
Current Sense
Voltage Sense
Temperature Sense
USB interface
3. ML4022-MCB Hardware
The subsequent sections cover the essential parts in the hardware, for board operation and
testing.
3.1 Power-Up
To power up the ML4022-MCB host, steps are as follow:
The host TOP is where the cage is mounted
Two options are available to power up the board:
Using the four pins power connector (J43) that should be connected to 5V AND 3.3V
taking into account pins distribution, where the SMD jumper (U168) must be
populated
Using the banana plug (U6) that should be connected to 3.3V where the SMD jumper
(U167) must be populated
Connect the host to your PC using a Type-B mini to Type-A USB cable.

3.3 LED Indicators
The ML4022-MCB includes on-board LEDs, for quick debugging and monitoring purposes. LEDs
are summarized below:
LED D1 indicates whether a USB cable is plugged or not.
LEDs D2 and D4, colored green and red, respectively, are used for diagnostic purposes:
If D2 is on: USB is locked and device is recognized by the USB driver
If D4 is on: USB is not connected or USB driver is not found
If both are off: board is not powered correctly or firmware is corrupted
If both are blinking: the board is in Bootloader mode
Led D10: Mod_Abs signal monitoring
Led D12: Los signal monitoring
LED D16: LosDD signal monitoring
LED D11: Tx_Fault/Int signal monitoring
LED D24: Tx_FaultDD/IntDD signal monitoring
3.4 Low Speed Signals
3.4.1 External I2C
The I2C bus can be accessed externally using U152 pins. In this case a jumper should be
placed on pin header J2 (HW_I2C) shown in the image below.

3.4.2 External HW Control
Also Low Speed Signals are controllable using an external source, this can be done
through control signals pin headers. In this case a jumper should be placed on pin
header P19 (HW_CTRL) shown in the image below.
Figure 2: External Control Signals
The low speed signals circuit shown below shows the connection of these signals to the
microcontroller and SFP-DD connector.
Figure 3: Low Speed Signals Schematics
When the jumper is inserted on P19, the output signals are tri-stated from the
microcontroller, and hence could be controlled from an external source.

4. ML4022-MCB Software
The ML4022-MCB is accessible and controlled through application software. This software is
MSA compliant and provides a user-friendly interface to operate the board and access all its
features. The communication between the ML4022-MCB board and the software is established
through USB connection.
4.1 USB Driver
In order to be able to communicate with the board, user need to install the USB driver of the
ML4022-MCB. This is available on the website under the following link (USB Driver icon):
https://multilaneinc.com/products/ml4022-mcb/
Below is a brief guide on how to install the USB Driver:
-Power up the board
-Connect the board to the PC through USB cable
-Download the USB driver file
-Go to “Device Manager”
-Find the target device that need to install the driver
-Right-click on the device and select Update Driver Software
-Select Browse my computer for driver software
-Browse you PC and select the driver file
-Click Next and wait until the driver is installed
4.2 GUI
For GUI installation and operation, refer to the link below. GUI user manual is available for
detailed description (CMIS GUI Manual icon).

7. Bootloader
Accessing in bootloader mode allows the user to reprogram the microcontroller, this is done as
described below:
1. Connect a jumper on (J1) situated close to the microcontroller.
2. Connect a USB cable between the PC and Board.
3. Power up the board with a +3.3V supply.
4. LEDs (D2, D4) start blinking.
5. Remove jumper.
6. Open the software “Microchip USB HID Bootloader v2.3”.
7. Click on “Open Hex File”.
8. Choose the new FW to download.
9. Click on “Program/Verify”.
10. Once the software finishes programming press on “Reset Device”.
11. After reset the Firmware is successfully updated.
