USB to 4-Port RS232 Serial Adapter Cable
$3.80 – $8.00 / pc · MOQ 500 pcs
A USB to 4-port RS232 serial adapter cable, 1.2 m: turn one USB connection into four DB9 serial ports for modems, POS gear, barcode readers and more.
- Description
A four-port serial adapter for the PC that has to talk to several RS232 devices at once. One USB connection fans out to four serial ports, so a modem, a barcode reader, a POS device and a label printer can all run from a single spare USB socket rather than needing four separate adapters and four ports.
It is plug and play for outside peripherals, fully compliant with USB Spec Rev 1.1 and compatible with USB 2.0 ports, and it ships with the driver CD. The 1.2 m cable keeps the breakout close to the machine.

A word on what it connects: RS232 peripherals such as modems, ISDN adapters, digital cameras, serial mice, barcode and card readers, PDAs, POS terminals, drawing tablets, label writers, fingerprint readers and security systems.
