1.5ft female to female serial null modem cable (7 wire type and full handshaking) connects your computer to device with COM port RS-232 compatible interface Wired as a 9 pin serial port Null-Modem cord that 2-3, 4-6, 7-8 line are cross linked (TX,RX,RTS, CTS, DTR,DSR wires are connected); standard shielded DE9 rs232 cable female to femalewith AL foil DB9 female to female connector on each end equipped with screws to ensure an easy and solid connection for stable serial cross data communication The wires inside are of 30AWG gauge and easy to solder to, and they connect to the pins in the order of the standard wire color code 1.5 feet short null serial adapter f/f for hooking up PC laptop to some old RS232C equipment like scanner, Modem, printer, plotter, camera, barcode / embroidery machine, touchscreen, microcontroller, factory test equipment Full Handshaking Signal RS-232 Cross over Cord (All Wire Connected) Note: 1. It’s a RS232 serial crossover cable female to female port, DO NOT perform straight through function. 2. It’s not a 15 pin VGA cable to connects computer to monitor, is only for RS 232 communication port to interface one system to anther system. 3. Shielded with standard Foil-Al layer shielding as most cables do, it fits for most of jobs. Transfer data between two devices using a RS-232C serial communication protocol If your equipment require full wire null modem cable (full handshaking signal), take this 1.5 foot 9 pin serial null modem cable wherever you need it, it allows you to add your RS232 peripherals to an application or replace your old cross-linked cables. The serial DB9 cable female to female chord is with gold plated pins for superior corrosion resistance ensuring a solid connection. The DB-9 connectors are equipped with a pair of thumbscrews for securing the plug to the male socket.
