RS232 D-Sub 9 pin normal density connectors. They can even be used for monochrome or CGA/EGA monitor cable extension. DB9 or DE9 female Solder Type Connector, D-SUB Solder Type Connector. EMI/RFI shielding blocks out noise and interference. Connect your computer equipment, match cable genders, and protect your I/O board or motherboard. They also employ gold-plated contacts for superior data retention and corrosion resistance. Please Note: Once ordered, this product cannot be cancelled or returned for credit. They have molded connectors, are fully shielded, and are lead-free for RoHS compliance (and all-around environmental friendliness). 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. 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. Your mount MUST be connected with a straight-through cable. This cable can be used for converting your DB9 RS-232 port to DB25 RS-232 port. 1 x DB9 female 1 x DB9 male RS-232 (TIA/EIA) specification Suitable for indoor use LED indicator: 9 x bicolour, red (V+), green (V-) Plug & Play. 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. Unfortunately, I need to change the system to accommodate new instrumentation and software. And the flunky at the big box computer store is no help. The CBL-DB9FDB25M-1 is a 10ft (3m) long DB9 female to DB25 male conversion cable. Hi all, I built a circuit with an Arduino board that integrated a pH and pressure sensor. (Maybe it isn't considered politically correct!) It is simply ridiculous. Many are not even labeled as to their orientation. DTECH DB9 serial cable female to female connects your computer to device with RS-232 compatible (COM port) interface RS232c cable 9 pin connector on each. Then there is every possible configuration of male / female plug - with locking screw or nut, without locking screw or nut. The reversing cables are also called crossover cables, null cables, modem cables, and null modem cables just to add to the confusion. 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.
