Refer to the Specifications section of the SEL-3031 manual for further setting details and limitations. Power Supply and Alarm Contact Output Connector. The SEL-3031 operates from a 9 30 Vdc power supply. The contact output is normally closed. If the SEL-3031 is enabled and operating correctly, the contact is held open. If the SEL-3031 detects an error or if power is turned off, the contact closes. You can use this contact to alert other equipment to a problem with the SEL Antenna Connector. The antenna connector is a TNC type. About RF exposure. The SEL-3031 transmitter module is approved for use only with specific antenna, cable, and output power configurations that have been tested and approved for use. Modifications to the SEL-3031, the antenna system, or to the power output that have not been explicitly specified by the manufacturer are not permitted and may render the radio noncompliant with applicable regulatory authorities. The radio equipment this manual describes emits radio frequency energy. The antenna(s) for this transmitter must not be collocated or operated in conjunction with any other antenna or transmitter. CAUTION Although the power level is low, concentrated energy from a directional antenna may pose a health hazard. Do not allow users to come closer than 23 cm (9 in.) to the antenna when the transmitter is operating in indoor or outdoor environments in the 900-MHz band. SEL-3031 Quick-Start Guide Date Code

7 Getting Started 7 Step 10. NOTE: The SEL-3031 has four Access Levels: 0, 1, 2, and CAL. At Access Level 0, no user interaction is available to the SEL The SEL-3031 reverts automatically to Access Level 0 if there are no keystrokes after a user-defined period of time. At Access Level 1, you can view settings and monitor the status of the device. At Access Level 2, you can monitor the status of the device and change settings. Access Level C is for factory use and for SEL assistance with troubleshooting. Users should not access this level. The device will display the message Invalid Access Level if you try to access commands (described later in this document) inappropriate for the access level in which you are working. Type ACC <Enter> to go to Access Level 1. The device will prompt you to enter the Access Level 1 password (the default password is OTTER; as the following text explains, this password can and should be changed to something only you know). The device displays the => prompt upon successful transition to Access Level 1. At Access Level 1, you can view device health and status, but you cannot change configuration. As an example, type STA <Enter> to view the SEL-3031 status. Step 11. At the => prompt, type 2AC <Enter> to go to Access Level 2. The device will prompt you to enter the Access Level 2 password (the default password is TAIL; as the following text explains, this password can and should be changed to something only you know). The device displays the =>> prompt upon successful transition to Access Level 2. At Access Level 2, you can change settings and view device health and status. Step 12. NOTE: In an SEL-3031 point-to-point configuration, one radio must be set to MASTER mode and one to REMOTE mode. The default is REMOTE mode. Designate one of the radios in a point-to-point (P2P) configuration to be the master mode radio and change its radio mode by typing SET R MODE <Enter>. Type MASTER <Enter>. Then type END <Enter> and Y <Enter> to save your changes. If the radios were at factory-default settings, this settings change should make the LINK LED turn green on both radios. NOTE: The maximum equivalent, or effective isotropically radiated power (EIRP), for the 900-MHz ISM band is 36 dbm, which includes 30 dbm maximum transmit power and 6 dbm antenna gain. The default power output for the SEL-3031 is 30 dbm. Based on your antenna gain, set the SEL-3031 power output to provide a reliable transmit/receive connection that does not exceed maximum EIRP regulations.

NOTE: You can use a USB-to-serial cable (SEL-C662) instead of an SEL-C245A cable if your PC has no serial port. If you use an SEL-C662 cable, then set the DTE/DCE switch to DTE for this process. Connect the EIA-232 cable (SEL-C245A) to the PC1 serial port (COM1) and Radio 1 Serial Port 1. Connect the EIA-232 cable (SEL-C245A) to the PC2 serial port (COM1) and Radio 2 Serial Port 1. Use connection settings of bps, 8 data bits, 1 stop bit, no parity, and local echo off to establish terminal sessions on both PCs to COM1. Testing the Final System Step 19. The characters you type in the terminal session on PC1 will display in the terminal session on PC2 and vice-versa. If you encounter difficulties, refer to Table 6. Performance Monitoring, Testing, and Troubleshooting This section provides information on monitoring radio performance, testing, and troubleshooting. The extensive self-tests with which the SEL-3031 is equipped have eliminated or greatly reduced traditional periodic test procedures. See the SEL-3031 manual (available at for more information on how to monitor and improve radio performance. Table 6 Troubleshooting (Sheet 1 of 2) Symptom Probable Cause Corrective Action ALARM LED is ON ALARM LED flashes ON every half second. Radio recognized a status failure. Radio detected a VSWR error where there is an open or short on the antenna port. Turn unit off, and then on, and issue the STATUS command. If alarm signal returns, return unit to the factory for repair. Verify that all connections from the antenna to the radio are secure. Verify that the antenna, feedlines, or lightning arrestor are not damaged. Date Code SEL-3031 Quick-Start Guide

10 10 Firmware Upgrade Instructions Table 6 Troubleshooting (Sheet 2 of 2) Symptom Probable Cause Corrective Action The SEC LED is flashing. Cannot connect to the radio through the USB port. Cannot change radio settings. Wall-mount radio will not turn on. The remote radio will not link up to the master. The SEL-3031 properly detects the encryption card, but the card is in reset and does not have the key set. USB driver not installed properly. Invalid password. The polarity of the power supply wires is reversed. Radio address or mode is set incorrectly. Antennas are not aimed correctly, or there is a bad antenna cable. Firmware Upgrade Instructions Use ACSELERATOR QuickSet SEL-5030 Software and set the KEY setting. This setting must be the same on both radios. You can find this software at Check for active SEL-to-USB drivers from your PC in the Ports section of the Device Manager. If that does not work, uninstall and reinstall the driver and restart your PC. Make sure the SEL-3031 is on before you plug in the USB cable. Install the password disable jumper and change passwords using the PAS command. See the Installation section in the SEL-3031 manual for information on how to disable passwords. Check the correct polarity and reverse if incorrect. The master and remote radios must be set to the same address and have the same SKIP settings. Check that the master radio LINK light is ON and that the NID address and SKIP setting are set correctly on both units. Use ACSELERATOR QuickSet on the radio to issue the RAD command to check for signal strength. If the signal is low, try to re-aim both antennas to gain signal strength and check for bad antenna cables. Refer to the Installation section in the SEL-3031 manual for more information on proper radio installation. SEL may occasionally offer firmware upgrades to improve the performance of your radio. The radio stores firmware in Flash memory, so changing physical components is not necessary. Step-by-step installation instructions are provided with all SEL firmware updates.
