A straightforward USB to RS232 cable for connecting serial equipment to PCs. 1.8 metre length gives convenient reach for most setups.
Reliable serial translation – thanks to PL-2303 chipset
PL-2303 chipset converts USB signals to RS-232 levels and supports a wide range of host operating systems. Driver packages for older Windows, MacOS and Linux kernels allow the serial COM port to appear to host software.
Stable serial links reduce connection errors when programming routers, modems or configuring industrial kit. Fewer dropped sessions means less time troubleshooting communication problems.
Broad device compatibility – with full-size DB9 female connector
Standard 9-pin DB9 female wiring preserves the original RS-232 pinout so existing serial cables and peripherals remain compatible. The USB Type A male interface plugs into typical PC USB ports.
Works with a wide range of serial equipment such as barcode scanners, label writers and legacy handhelds without rewiring. Keeps existing cable stock usable, avoiding additional adaptors.
Flexible installation – thanks to 1.8 metre cable length
A 1.8 metre (6ft) lead provides distance between host and peripheral while maintaining signal integrity over short runs typical for RS-232. Standard connectors keep mechanical connections secure.
Gives room to position equipment away from cramped PC locations and server racks. Reduces the need for rearranging furniture or buying extension leads.
