Please Note: These are only sample labels; different products contain different identifiers. The actual identifiers should be seen on
your devices if applicable.
Regulatory Requirements / Exigences Réglementaires
WARNING:
To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance of 23 cm or more should be maintained between
the antenna of this device and persons during device operation. To ensure compliance, operations at closer than this distance is not recommended.
The antenna used for this transmitter must not be co-located in conjunction with any other antenna or transmitter.
WARNING:
Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any
interference received including interference that may cause undesired operation.
WARNING:
Changes or modifications not expressly approved by Microhard Systems Inc. could void the user’s authority to operate the equipment. This device
has been tested with UFL to Reverse Polarity SMA connectors with the antennas listed in Appendix A When integrated in OEM products, fixed
antennas require installation preventing end-users from replacing them with non-approved antennas. Antennas not listed in the tables must be
tested to comply with FCC Section 15.203 (unique antenna connectors) and Section 15.247 (emissions).
WARNING:
MAXIMUM EIRP
FCC Regulations allow up to 36 dBm equivalent isotropically radiated power (EIRP). Therefore, the sum of the transmitted power (in dBm), the
cabling loss and the antenna gain cannot exceed 36 dBm.
WARNING:
EQUIPMENT LABELING
The FCC and IC numbers depend on the model of the radio module. Do NOT use the Marketing Name of the product but the Model to distinguish
the Certifications Numbers. This device has been modularly approved. The manufacturer, product name, and FCC and Industry Canada
identifiers of this product must appear on the outside label of the end-user equipment.
WARNING:
This device complies with Industry Canada’slicense-exempt RSSs. Operation is subject to the following two conditions:
(1) This device may not cause interference; and (2) This device must accept any interference, including interference that may cause undesired

2.0 Quick Start
To reset to factory
defaults, press and
hold the CONFIG for 8
seconds with the
pMDDL5824 powered
up. The pMDDL5824
will reboot with factory
default settings.
This QUICK START guide will walk you through the setup and configuration of a few
basic applications. The QUICK START will rely on the WebUI for configuration. This
walkthrough also assumes the units used are installed in microhard interface/
development boards or custom boards that allow access to the LAN port. See the
appropriate section for pin-outs.
Note that the units arrive from the factory with a Radio Configuration of ‘Master’
and the Local Network setting configured as ‘Static’ (IP Address 192.168.168.1,
Subnet Mask 255.255.255.0). DHCP is enabled by default, and will assign an IP to a
connected device or computer with DHCP enabled.
2.1 Getting Started
✓ Connect the appropriate Antenna(s) to the pMDDL5824.
✓ Connect and/or apply a suitable power source to the unit. Allow the unit to boot
up fully, the CPU LED (Blue) should be on in a solid state
✓ Connect A PC to the LAN port of the pMDDL5824 Dev Board, using an Ethernet
Cable.
✓ The PC must have its Network Setting (TCP/IP Properties) set to DHCP (The mo-
dem will assign a IP address to you), or STATIC with an IP Address of (e.g.)
192.168.168.10 and a Subnet Mask of 255.255.255.0.
✓ Open a Browser Window and enter the IP address 192.168.168.1 into the ad-
dress bar.
The factory default
network settings:
IP: 192.168.168.1
Subnet: 255.255.255.0
LAN
192.168.168.1

2.0 Quick Start
✓ The pMDDL5824 will then ask for a Username and Password. Enter the factory
defaults listed below.
✓ Once successfully logged in, the System Summary window will be displayed.
The factory default login:
User name: admin
Subnet: admin
You will be forced to
change the default
password upon logging in
for the first time.
The Factory default login:
User name: admin
Password: admin
Once successfully logged in for the first
time, the pMDDL5824 will force a pass-
word change

2.0 Quick Start
2.2 Simple Master and Slave - Auto (Using Defaults)
This Quick Start example requires (2) pMDDL5824 units, one will be configured as
a Master (M), the second unit will be configured as a Slave/Remote (S). This exam-
ple will use factory defaults to set up each unit so that a simple network will be es-
tablished.
✓ Use Section 2.1 Getting Started to power up a pair of pMDDL5824 modules
mounted in a Pico Ethernet Motherboard.
✓ Master: Once the pMDDL5824 is fully booted (solid blue CPU LED), press and
hold the CFG button. Once the CPU LED begins to flash, continue to hold for at
least 10 seconds, then release.
✓ The pMDDL5824 will then reset all settings to default values, and set the follow-
ing settings that are required to automatically create a link with a slave:
- IP Address: 192.168.168.1, Operating Mode: Master
- Network ID: pMDDL, Channel Bandwidth: 8 MHz
- Channel-Frequency: 76 - 2477 MHz
✓ Slave: Ensure the pMDDL5824 is fully booted (solid blue CPU LED), then press
and hold the CFG button. Once the CPU LED begins to flash, continue to hold for
5 seconds, then release.
✓ The pMDDL5824 will then reset all settings to default values, and set the follow-
ing settings that are required to automatically create a link with a slave:
- IP Address: 192.168.168.2, Operating Mode: Slave
- Network ID: pMDDL, Channel Bandwidth: 8 MHz
- Channel-Frequency: 76 - 2477 MHz
✓ Once both units have finished changing settings (~60 seconds) a wireless link
should automatically be established between them, this can be seen by observ-
ing the RSSI LEDS, they should be on solid, indicating a link (the more LEDs il-
luminated = stronger the link).

2.3 Simple Master and Slave — Manual Setup
This Quick Start example requires (2) pMDDL5824 units, one will be configured as
a Master (M), the second unit will be configured as a Slave/Remote (S). This exam-
ple will show the basic steps required to set up each unit so that a simple network
will be established.
For the best performance it is required to connect the Master to the video source (camera) and
the remote to the video receiver. The pMDDL5824 can support Point-to-Multipoint applications
and multiple remotes could be used to view the video from multiple locations.
2.3.1 Configuring the Master
✓ Use Section 2.1 Getting Started to connect, power up and log in to a
pMDDL5824 unit.
✓ Give the pMDDL5824 unit a unique IP address.

Select Network from the top/main
navigation.
Select LAN from the submenu list.
Select Edit on the LAN interface 1.
Choose Static IP for the Connection
Type.
Enter the following Network

If any additional
settings need to be
changed, ensure they
are also changed on
the Slave.
Select Master from the Operation
Mode dropdown box.
Set a Network ID, which will need
to be the same on each unit in the
network. This example uses
TEST_ID.
Select Wireless from the top/main navi-
gation, and then RF from the submenu
list.
For bench or close proximity testing
it is best to use a lower power setting
to prevent RF saturation. Select
20dBm from the TX Power setting.
The remaining settings in the Wireless menu
should be left as defaults for this exercise.

2.3.2 Configuring the Slave/Remote
The following procedure describes the steps required to set up a pMDDL5824 unit
as a Slave (S). A Slave provides a single wireless connection (i.e to an Master) and
provides a wired connection to a PC or other devices.
✓ Use Section 2.1 Getting Started to connect, power up and log in to a second
pMDDL5824 unit.
✓ Give the pMDDL5824 unit an unique IP address.
Choose Static IP for the Connection
Type.
Enter the following Network
Information:
IP Address: 192.168.168.12
IP Subnet Mask: 255.255.255.0
Default Gateway: 192.168.168.11
Click on the Submit button to write the
changes to the pMDDL5824. The Cancel
button will revert back to last values
saved to the unit.
Once the IP Address is changed, you
will need to type the new address into

ration.
