The CON-485-PE9 Is A Bi-directional Port Powered RS232 To RS485 Converter Which Converts A Full-duplex RS232 Port To A Half-duplex Two-wire RS485 Port.

Ports Two separate terminal blocks, a rugged terminal block and a terminal block with built-in 120 Ohm termination are included with the product for maximum flexibility. The terminal blocks plugs into the RS485 port, providing screw-lug wire terminations for the port. CON-485-PE9 RS232 to RS485 Converter plus block The CON-485-PE9 is a bi-directional port powered RS232 to RS485 converter which converts a full-duplex RS232 port to a half-duplex two-wire RS485 port. A built-in data direction auto-turnaround feature automatically enables the RS485 driver when data is present from the RS232 port, eliminating the need for software drivers, and making the device fully plug-and-play. Plug-and-Play (Device is Hot-pluggable) Two Terminal Blocks Included, One Rugged and the Other With Optional 120 Ohm Termination Data Direction, Auto-turnaround, No Flow Control is Necessary Both terminal blocks include fastening hardware. Rugged Sealed Terminal Block This is a rugged terminal block which is sealed to provide protection from the elements and vibration.
