Installation Guide

Raven Series Category Cabling Guidelines
The Raven Series requires a minimum grade of Category 6a cabling to be used in order to reach 100m (330 ft) of extension distance.
NOTE: The total distance of 100m also includes the length of the patch cable should one be required. Up to 10m of patch cable can be used, although the remaining 90m distance must consist of solid core premise cabling.
Furthermore, depending upon specific application requirements, it is recommended that installers keep in mind how they intend to pull/route the link cable and whether to use Shielded or Foiled cable where appropriate.
When installing this product, it is appropriate to use Unshielded (UTP) cabling if the cable run installation meets the following requirements:

• The cable is not bundled with other cables
• The cable is run loosely with other Category cables
• The cable is not placed close to sources of interference such as power lines and radios
• The cable is not looped or coiled

When installing this product, Foiled (FTP) or Shielded (STP) cabling must be used if the cable run installation requires the following cable run installation:

• The cable is bundled with other cables
• The cable is run tight against other Category cables
• The cable is placed near sources of interference like power lines and radios
• The cable is looped or coiled

NOTE: For best performance install Raven 3204C Pro using Shielded or Foiled CAT 6a/7 cable.

Pairing the LEX and REX Units
When bought as a complete system, that consists of both a LEX and a REX, the extenders will be paired with each other out of the box, so no pairing action should be required. However, if extenders are bought individually, individual extenders have been installed, or you simply wish to change the LEX and REX pairings across a network, then the following steps must be taken.

NOTE: The following steps apply to both Raven 3204C Pro direct connect and network connect configurations.

1. Ensure the LEX and REX units are either directly connected to each other or are connected to the same subnet on your network.
2. Press and hold the Mode button on the front of the LEX unit. Release the button within 10 seconds. The Link LED will start flashing and this indicates that Pairing Mode has been activated on the LEX.
3. Within 10 minutes of activating the pairing mode on the LEX unit, press and hold the Mode button on the front of the REX unit. Release the button within 10 seconds. The Link LED will start flashing and this indicates that Pairing mode has been activated on the REX unit.
4. The Link LED on both units may start flashing more slowly before finally turning on. Once the Link LEDs are solid, the link is established between both extenders.

NOTE: If more than 10 minutes passes before the units are paired, then the extenders will switch back to regular mode and reestablish the previous links they had, if any.
NOTE: To cancel pairing mode, press and hold the Mode button a second time. Release it within 10 seconds.

Unpairing an Extender
If for any reason an extender needs to have its pairing removed, this can be done by pressing and holding the Mode button for longer than 10 seconds. Once this is completed, the unit will not be paired to any other extender.

Warranty Information

Limited Hardware Warranty
Icron, an Analog Devices brand, warrants that any hardware products accompanying this documentation shall be free from significant defects in material and workmanship for a period of two years from the date of purchase. Icron’s hardware warranty extends to Licensee, its customers and end users. The Warranty does not include repair of failures caused by misuse, neglect, accident, modification, operation outside a normal operating environment, failure caused by service of the device by non-authorized servicers or a product for which Icron is not responsible. Opening the enclosures will void warranty.
Hardware Remedies
Icron’s entire liability and the Licensee’s exclusive remedy for any breach of warranty shall be, at Icron’s option, either (a) return of the price paid, or (b) repair or replacement of hardware, which will be warranted for the remainder of the original warranty period or 30 days, whichever is longer. These remedies are void if failure of the hardware has resulted from accident, abuse, or misapplication.
Limitation of Liability
The hardware warranty set forth in this agreement replaces all other warranties. Icron expressly disclaims all other merchantability and fitness for a particular purpose and noninfringement of third-party rights with respect to the hardware.
Icron dealer, agent, or employee is not authorized to make any modification extension or addition to this warranty. Under no circumstances will Icron, its suppliers or licensors be liable for any costs of procurement or substitute products or services, lost profits, loss of information or data, or any other special, indirect, consequential, or incidental damages arising in any way out of the sale of, use of, or inability to use Icron product or service, even
if Icron, its suppliers or licensors have been advised of the possibility of such damages. In no case shall Icron, its suppliers and licensors’ liability exceed the actual money paid for the products at issue.
Since some jurisdictions do not allow the limitation of implied warranties of liability for incidental, consequential, special or indirect damages, the above limitation may not always apply. The above limitations will not apply in case of personal injury where and to the extent that applicable law requires such liability.

Technical Glossary
Category 6a/7 (CAT 6a/7) Network Cabling
Category 6a/7 cable is commonly also referred to as CAT 6a or CAT 7. This cabling is available in either solid or stranded twisted pair copper wire variants and as UTP (Unshielded Twisted Pair) or STP (Shielded Twisted Pair). UTP cables are not surrounded by any shielding making them more susceptible to Electromagnetic Interference (EMI). STP cables include shielding the copper wires and provides better protection against EMI.

USB 3, USB 2.0 and USB-C Cables
USB cables have two distinct full-sized connectors. The Type A connector is used to connect the cable from a USB device to the Type A port on a computer or hub. The Type B connector is used to attach the USB cable to a USB device. The Type-C connector is used to connect to both USB hosts and devices.

RJ45
The Registered Jack (RJ) physical interface is what connects the network cabling (CAT 5e/6/7) to the LEX and REX units. You may use either the T568A scheme (Table 1) or the T568B scheme (Table 2) for cable termination as this extender system requires all four pairs of the cable. RJ45 connectors are sometimes also referred to as 8P8C connectors. Note that any given cable must be terminated using the same T568 scheme on both ends to operate correctly.
