Product Description

The PFWB5-30n and PFWB5-30ac are wireless bridges designed for high-speed data transmission.

Specifications

Model Name	Frequency	Transmit Power	EIRP	Antenna Gain	Power Supply	Power Consumption
PFWB5-30n	5.150-5.850 GHz	29 dBm (country dependent)	44 dBm (country dependent)	15 dBi	24 V DC Passive PoE	4.5 W
PFWB5-30ac	5.150-5.850 GHz	30 dBm (country dependent)	45 dBm (country dependent)	15 dBi	24 V DC Passive PoE	10 W

PoE Connection

Use the provided 24 V DC passive PoE injector. Connect the Ethernet cable from the injector to the device's ETH+POE port. The power cord depends on the region.

Important Note: For all wired Ethernet connections, use shielded Category 5 (or higher) cabling and ground it through the AC power of the PoE. For outdoor installations, it is recommended to use Ethernet surge protectors near the device to absorb voltage spikes and dissipate them to the ground.

Step 3: Wireless Configuration

Navigate to 'Settings > Wireless Configuration'. Set the frequency and channel. Set the wireless operating mode to 'Access Point (auto WDS)'.

Available operating modes include: Access Point (auto WDS), Wireless Access Point (TDMA2), Access Point (TDMA3), Station (WDS/TDMA2/TDMA3), and Wireless Client (ARPNAT).

Click the settings icon in the bottom right corner of the SSID, set the SSID and security information, and then click 'Done'.

Notes:

A device connected to a camera should be set to 'Station (WDS/TDMA2/TDMA3)' mode.
A device connected to a machine room should be set to 'Access Point (Auto WDS)' mode.
Wireless Client with 'Client (ARPNAT)' mode is used with an access point that does not support standard WDS mode.
Select WDS mode to ensure transparent data transmission.
