    Set TXMODE equal to P (Paced). To connect the relay to the radio, use an SEL-C285 cable (DB-9 male-to-DB-9 male straight-through). If complete electrical isolation is desired between the radio and antenna and the EIA-232 communications port of the relay, use the SEL-2812MR Fiber-Optic Transceiver and fiber-optic cable to connect the relay to the radio.

    For easy installation order the SEL-2505 with the SEL-2812 fiber-optic option (SEL-2505x6xXX). Use multimode SEL-C808 or SEL-C807 ST terminated fiber-optic cable to directly connect the SEL-2505 to an SEL-3031 equipped with a fiber-optic option for Port 1. Other transceiver models can be used as long as the corresponding SEL-2800 family transceiver is used on both ends.

    The required settings for the SEL-351 are shown in Figure 3.9. These settings are similar to all of the SEL-351, SEL-311, and SEL-700 series of relays. To establish a communications link via the radio, the most critical settings are PROTO, SPEED, BITS, PARITY, STOP, and RTSCTS.

    Easily check this by looking at the master SEL-3031 Tx and Rx LEDs on Port 1. If the Tx LED illuminates, and the Rx LED illuminates shortly after, the link is up and working. If you only see the Tx LED illuminate and not the Rx LED illuminate you either have a problem with the settings in the radio, settings problem on the SEL-651R, or you are using the wrong cable.

    To improve the dependability when using ™ collocated antennas the radio comes with SEL Hop-Sync technology. SEL Hop-Sync technology allows you to connect collocated antennas together and synchronizes all the radios connected so they hop at the exact same time.

  • Page 66: Appendix C: Sel-3044 Encryption Card

    SEL-3044 Encryption Card Overview The SEL-3044 Encryption Card is a standalone card that can be added to the SEL-3031 to encrypt the radio data being sent between SEL-3031 radio links. The SEL-3044 can be ordered at time of purchase or added as an upgrade. The SEL-3044 requires one setting to provide a very strong level of encryption over the radio link.

  • Page 68 The SEL-3044 provides data encryption with a cryptographic key strength of 256 bits. The SEL-3044 RNG is designed so that all possible key values are equally likely. It is widely accepted throughout the cryptographic community that it is not realistically possible to mount a successful brute force (key guessing) attack on a 256-bit key space with technology available today.

  • Page 69: Figure C.2 In-Band Data Packet Format

    SEL-3044 devices. It also provides a cryptographic authentication mechanism for rejecting session requests by unauthorized devices. Session keys provide encryption of all protected user data prior to transmission. An SEL-3044 produces session keys at system startup, and periodically during sessions, using the process outlined by FIPS 186-2.

  • Page 70: Figure C.3 Operation Of The Aes Encryption Function

    K1 for encryption and K2 for decryption. The AES encryption algorithm the SEL-3044 uses is a symmetric block cipher with an encryption/decryption key size of 256 bits. The AES is the latest encryption standard adopted by NIST. In 1997, NIST challenged the cryptographic community to develop the next generation encryption algorithm to replace the aging DES and 3DES encryption standards.

Installing an SEL-3044 in the SEL-3031 The SEL-3044 can be ordered at time of purchase of the radio, or it may be added later as a field upgrade. The process involves powering down the radio, removing hardware, installing the card, and setting the radio.
