Local time-averaged RSSI The RSSI averaged over the last 16 transmissions. Used in analyzing the strength and quality of the transmit signal. Local instantaneous RSSI The value of RSSI for the last transmission. Used in analyzing the strength and quality of the transmit signal. D/A / A/D Loopback Factory Diagnostic. Fig. 16 — Quick Configuration Window Unit Testing — You can test the operation of transceivers in a variety of ways using the Configuration Manager. The instructions in this section assume that the Configuration Manager is correctly installed and the transceiver is properly connected to your PC. The test string is transmitted to the Destination Unit and looped back to the Source Unit. The RX Pane shows the test string as received by the transceiver connected to the computer after being loopbacked from the remote transceiver. If no data is received within the timeout period the message “Timeout” is printed in the RX Pane. The TX Pane shows the test string as typed in the dialogue box. To perform a communication link test it will be necessary to use two Carrier wireless transceivers, two antennas, a loopback connector and a computer. Perform the following tests: • Terminal mode • Loopback test (Stand-alone model only) TERMINAL MODE TEST — The Terminal Mode tab provides a simple terminal interface from which data can be sent between two units configured as a Broadcast Remote-to-All Host and Remote Pair. Anything typed in the input field of transceiver no. 1 will immediately be transferred to transceiver no. 2. The data is displayed in the transmit pane for transceiver no. 1 and the receive pane for transceiver no. 2. (NOTE: You will only see received data if the destination transceiver is connected to a PC with Configuration loaded and open or if the destination PC’s transceiver has a loopback connector.) What You Need: • Two transceivers (A and B) configured as a host to remote. The Source Unit ID of unit A equals the Destination Unit ID of unit B and vice-versa. In addition, both units must have matching Vendor ID numbers, Network ID numbers and Hop Table numbers. • One of these units is connected to a PC with the Configuration Manager loaded. 11 Test Communications Between Units: 1. Open the Configuration Manager. See Fig. 17. 2. Click the Terminal Mode tab. 3. In Test String, enter some text. 4. Click Resend. The test string is transmitted to the Destination Unit. LOOPBACK TEST — The Loopback Test screen allows you to perform two functions; to test that two units can communicate and to determine the best placement of one unit relative to another based on received signal strength. This test is only used for stand-alone models. What You Need: • Two transceivers (A and B): configured as a Broadcast Remote-to-All and Host Pair. The Source Unit ID of unit A equals the Destination Unit ID of unit B and vice- versa. In addition, both units must have matching Vendor ID numbers, Network ID numbers and Hop Table numbers. Transceiver A is connected to a PC loaded with the Configuration Manager. NOTE: Test also works with host/remote set up. • Loopback connector: Transceiver B (the one not connected to the PC running this program) must have a loopback connector (pins 2 and 3 of the serial port tied together) on the serial port of the remote unit. A loop- back connector is delivered with all demo and developer kits. NOTE: Connect loopback connector to remote units if using a host to remote set up. Test Communications Between Units: 1. Open the Configuration Program. See Fig. 18. 2. Click the Loopback Test tab. 3. In Test String, enter some text. 4. Enter the desired criteria in other fields in this group. The default values are recommended for this type of testing. The minimum for Repeat Every field is 100 msec. 5. Click Start. Test the Placement of a Unit: 1. Click the Loopback Test tab. See Fig. 19. 2. Click Test. 3. Click Instantaneous RSSI. 4. Enter some text in the Test String. 5. Enter the desired criteria in other fields in this group. The default values are recommended for this type of testing. 6. Click Start. VIEWING DATA IN THE RX AND TX PANES — These display areas show the data being transmitted and received during tests. The RX pane shows data being received into the transceiver. The TX pane shows data being transmitted from the transceiver. All data sent will be displayed and at times the pane may become cluttered. You can use the Clear buttons on the toolbar or the commands in the Edit menu to clear the panes of data. To clear data in the panes, select Clear RX Pane or Clear TX Pane. If the RX pane displays Timeout? each time the Test String is sent then perform the following tests: • Vertify that both antennas are properly installed on the transceivers. • 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). • Attempt to utilize direct...
