Cradlepoint USB to RS232 Extensibility Cable, Screw-Lock USB-A to DB9, for R920

Vehicles still speak serial - OBD-II readers, dispatch terminals, industrial sensors - and the 170873-000 is how the R920 joins the conversation: an extensibility cable converting the router's USB 2.0 Type A port to a 9-pin DB9 RS-232 female connector. The USB end secures with a robust thumb-screw lock so vibration cannot back it out, the DB9/RS232 side needs no external power, and the 400 mm (1.31 ft) length keeps the adapter tight to the router instead of dangling slack in the cab. With the OBD-II cable on an R920 it enables vehicle diagnostics support, and it carries GPS data over the serial interface at USB 2.0's 480 Mbit/s ceiling. Vibration is what kills USB serial adapters in vehicles - the screw-lock shell is the difference between a diagnostic port and an intermittent mystery. Thread the locking USB-A into the R920, torque the thumb screw finger-tight, and mate the DB9 to the serial device. Configure the serial passthrough in NetCloud and the legacy equipment is on the network. Cloud Care Networks stocks the Cradlepoint 170873-000 alongside the gateways and routers it supports, so IT and field-service teams can consolidate antennas, spares, and replacement hardware on a single order.
