Security — Frequency hopping is inherently more secure than other RF technologies. In addition, each transceiver has a Carrier ID set in the firmware shipped straight from the factory. As the user configures each transceiver, additional network ID numbers may be provided and varying hop tables for independent networks may be assigned. The combination of firmware, software IDs, and frequency hopping technology ensures safe and secure data transmissions. Carrier wireless transceivers also support your data encryption software. Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations. 4 PC 111 Catalog No. 533-378 Printed in U.S.A. Form 33CN-1SI Pg 1 4-01 Replaces: New Book Tab 11a 13a PREINSTALLATION Every installer should perform site evaluation prior to installing the transceivers. In order to perform this evaluation the following minimum equipment must be purchased from Carrier. The two modem starter kit (33CNWIRMOD) is required to begin performing a site evaluation. The following components are in the two modem kit: 2 — standalone transceivers 2 — high gain omni-directional antenna 2 — transceiver power supplies 2 — RS-232 to RS-485 converters 2 — 9-pin RS-232 cables 1 — copy of transceiver configuration software 1 — loopback connector If the set up requires outdoor antennas they can be purchased from Carrier as part number 33CNOAANT1. High gain directional antennas may be required to establish reliable communications. Directional antennas can be purchased directly from the antenna vendors described in the antenna selection and location section of this manual. Site Evaluation Testing — Loopback Test — In order to perform a loopback test the transceivers must be configure Broadcast Remote-to-All. See the Remote-to-All configuration section of this manual. To perform a loopback test it is necessary to connect each modem (one host and one remote) to its power supply. Then connect a PC with the Configuration Manager software to a modem using the 9-pin RS-232 cable provided. Lastly, connect the second modem directly to the loopback connector. See Fig. 1. Perform the loopback test by executing the following steps: 1. Position the modems directly on top of each other and remove both modem antennas if connected. Use a host and remote pair for this test. 2. Run the Configuration Manager on the computer and log into the software using the username “oem” and password “oem”. 3. Select the Loopback Test program tab within the Configuration Manager software. 4. In the Test String dialog box enter a text string such as TESTING. 5. Using the pointer place a check in the Test check box. 6. Using the pointer select the Instantaneous RSSI option. 7. Press the Start button on the screen to begin sending the Test String. 8. The TX pane should start displaying the Test String at regular intervals. If the string is being received and sent back by the remote transceiver the RX pane should display the same text screen. If the Test String is successfully transmitted through the loopback connector with the transceivers on top of each other proceed to Step 10. 9. If the RX pane displays “Timeout?” each time the Test String is sent then perform the following tests: a. Verify that both transceivers are properly configured for Broadcast Remote-to-All operation. b. Verify that both antennas are removed from the transceivers (NOTE: if antennas are connected and located too close together the two antenna fields will cancel each other out). c. Verify that cycling power to the modems shows the 3-flash blink as described in the Getting Status section of this manual. Fig. 1 — Loopback Configuration 10. After successfully establishing communications between the two transceivers locally, locate the transceivers in their desired locations and repeat Steps 2 through 8. 11. If the text string is being received and sent back by the remote transceiver the RX pane should display the same text string. If the text string is successfully sent and received the transceiver and antenna locations are acceptable. The green sync light should remain lit once the first data is sent. 12. If the RX pane displays Timeout? each time the Test String, is sent them perform the following tests or the sync light will not remain on: a. Verify that both antennas are properly installed on the transceivers. b. Reposition the transceivers such that the green signal strength bar is as long as possible. Normally signal strengths above .5 are required for reliable communications (see Antenna Selection and Location section). c. Attempt to utilize directional antennas in order to obtain reliable communications (see Antenna Selection and Location section). INSTALLATION Hardware Installation — Prior to installing the transceiver( s), count and check all of the delivered equipment. A power supply and an antenna is required for each transceiver. The transceiver will be attached to either RS-232, R...
