All other pins are for modem control signal tests and are not necessary to connect unless you wish to test those signals. The tester runs software that detects requests from BurnInTest to start network testing and to send, receive and verify data from BurnInTest. (Soldering is optional and preferred) Cut the sheath on Blue and Brown and twist them together.
Pins marked in red are the data lines, Tx and Rx, and are necessary for the loopback and BERT testing. The Network Loopback Tester allows stability and load testing of network interfaces such as Ethernet, Wi-Fi and Bluetooth ports. For a Gigabit Ethernet Loopback you will also need to connect the other four wires as follows: Cut the sheath on Blue-White and Brown-White and twist them together. Use the diagram appropriate to your electrical interface.ĭB-9 RS-232 Loopback Connection (TIA-574) If you want to test modem control signals or you need to construct your own loopback, follow the instructions below. Tipically, I need to perform a loopback test on an electric Gigabit Ethernet port that with a normal RJ45 loop plug you cant perform due to the echo. Please contact your sales representative for more information. This is the simpliest version of a four pin self-loopback plug which is used to test interface rx/tx operations on FastEthernet (100mbit/sec) interfaces.
#LOOPBACK PLUG TO TEST AN ETHERNET PORT SERIAL#
Item number LB102 is a DB-25 loopback that is used to test RS-232 serial ports. Item number LB101 is a DB-9 loopback that is specially constructed to test data signals on RS-232 and Sealevel RS-422, RS-485 serial ports. Additional loopback plugs can be purchased for a small charge. Sealevel serial I/O devices typically include a loopback plug with each shipment that can be used to test data lines.
