![]() ![]() They can even be used for monochrome or CGA/EGA monitor cable extension. They also employ gold-plated contacts for superior data retention and corrosion resistance. There are a lot of variations of serial communicator protocols detailing the hardware (cables and connectors), bit rates, and what the data package itself looks like (start & stop bits, acknowledge, etc.), but suffice to say, most any modern usage of a DB-9 cable will be for a variant of the RS-232 protocol, which is ironic given that the RS. Type of Cable for DB-25 Connectors RS 232 Straight-through Cable. Cisco provides this cable with the 600, 800, 16 Series Routers. They have molded connectors, are fully shielded, and are lead-free for RoHS compliance (and all-around environmental friendliness). RJ-45 to DB-9 Female RJ-45 to DB-9 Female This cable is also known as Management Cable. We have found a source of genuine standard straight-through serial cables and selected these 15 foot cables as the most universally appropriate. Other serial cable types cross or reverse some of the wires making communication with your mount impossible. On PC’s, DB-9 connectors are typically used for RS-232 serial ports. The DB9 connector is commonly found on computers, electronic devices, DAQ equipment, and industrial controls. These connectors mate with any other standard DB-9 connectors. Straight-through cables are wired with the corresponding numbered pins of the connector wired to each other: pin #1 on the male end to hole #1 on the female end #2 to #2 and so on. D-SUB DB9 9 Pin Female Connector To IDC Female Connector With 10 Pin Flat Cable 30CM. Your mount MUST be connected with a straight-through cable. And the flunky at the big box computer store is no help. (Maybe it isn't considered politically correct!) It is simply ridiculous. Many are not even labeled as to their orientation. ![]() Then there is every possible configuration of male / female plug - with locking screw or nut, without locking screw or nut. Terminal Block Connector Converts the DB9 Male input connected to the Female DB-9 serial port to a terminal block connection for fast easy wiring applications. ![]() The low profile design reduces leverage strain on overstressed computer ports and is fully shielded for electrically noisy environments. The reversing cables are also called crossover cables, null cables, modem cables, and null modem cables just to add to the confusion. Description Dual-purpose slimline gender changers allow mismatched D-sub connectors to mate and are panel mountable to pass cables through a bulkhead (See panel mount tips). The most common source of computer / mount communication failure is the wrong cable! There are straight-through cables and reversing cables. You would think that a serial cable would be a straight-forward simple device that would be confusion- and mistake-proof. ![]()
