Use the loopback test in the X-CTU software to determine that packets can be transmitted correctly. Remove the loopback adapter and attach the radio modem. Use the loopback test in the XCTU software to determine that packets can be transmitted correctly. When the adapters are assembled, test the cable by attaching the loopback plug into the yellow adapter and the CAT-5 cable, and the green one into the PC and the CAT-5 cable. (This cable will be carrying RS232 signals, not ethernet signals.) To build an 8-wire RS232/RS485 serial cable for use with the Nema-4 enclosure, use a standard CAT-5 networking cable to act as the extension between the computer and the radio modem. (This cable will be carrying RS232 signals, not ethernet signals.)Īssemble both the yellow and green adapter according to this table: DB9 has the smallest footprint of the D-Subminiature connectors have 9 pins or 9 holes depending on whether they are male or female, and they are housed in the connector. ![]() To build a 3-wire RS232 serial cable ( 3-wire refers to the three signals: RXD, TXD and GND), use a standard CAT-5 networking cable to act as the extension between the computer and the radio modem. Posted on Decemby Ada Parker What is DB9 connector The term DB9 refers to a common connector type, one of the D-Subminiature or D-Sub types of connectors. : Db9 Female To Female 1-16 of 898 results for 'db9 female to female' Results DTech 15 ft Straight Through Serial DB9 Cable Female to Female 9 Pin COM Port Cord for Data Communication (5 Meter. Wire color (Ethernet cable - EIA/TIA 568B )Īn example application for these adapters would be to extend the RS232 serial connection so that the radio modem might be located closer to the antenna location so that the antenna cable will be as short as possible. Two adapters are available:ĭB9 Male to RJ45 connector, Yellow adapter (p/n:JE1D2-CDA-A)ĭB9 Female to RJ45 connector, Green adapter (p/n:JE1D3-CDA-A) These adapters are shipped unassembled so that they may be put together to accommodate the needs of the application. This cable can be used for converting your DB9 RS-232 port to DB25 RS-232 port. This machine-made, high-quality RS-232 conversion cable comes with a DB9 female connector on one end and a DB25 male connector on the other. ![]() Please confirm your currency selection: Mouser Electronics - Electronic Components Distributor. To facilitate adapting the DB9 connector interface to work with other physical connection types Digi offers RJ45 to DB9 adapters. The CBL-DB9FDB25M-1 is a 10ft (3m) long DB9 female to DB25 male conversion cable. Mouser offers inventory, pricing, & datasheets for Female 9 Position D-Sub MIL Spec Connectors. ![]() The Digi radio modem has the RS232 and RS485/422 signals available on a DB9 connector. In some situations it is necessary to interface the RS232 or RS485 signals to RJ45, terminal strips or other physical connections.
