CAS24-B9FSPS - Code Activated Switch for Async RS232 to RS485 (Bidirectional) or RS232 to RS422 (Bidirectional) Networks


Product Description

Code Activated Switch for Async RS232 to RS485 (Bidirectional) or RS232 to RS422 (Bidirectional) networks w/ 12V Power Supply & DB9F Adapter w/ 7ft. cable in Boxed Enclosure. 

  • Code activated switch for RS485 (2-wire, half-duplex) or RS485/RS422 (4-wire, full-duplex) multi-drop networks, using non-addressable RS232 target/remote devices. 
  • Network multiple RS232 devices over either RS485 (2-wire) or RS485/RS422 (4-wire), at distances up to 4000 ft. and data rates up to 115.2Kbps. 

  • Software/hardware configuration of "Node address," Data rate, Parity, "Attention character," Unit address, time-out value, and operating modes. 

  • Think of the CAS24 as an addressable interface converter that can communicate with RS232 devices using the same and/or different protocols/command structures.

  • Other CAS models available with multiple ports - please call for information 513-874-4796 or 513-638-0228

The CAS24 "Code activated switch" allows RS232 devices that are normally non-addressable and only usable in point-to-point applications to be added to new or existing RS485 and/or RS422 networks. User programmable settings allow the CAS24 to be used as a versatile tool for constructing networks of almost any size (2-1000+ nodes).

The unit has jumpers for bias, termination, RS232 DTE/DCE selection, mode control, and "external/hardware" unit address (see manual and schematic).The unit has edge mounted LED indicators, a removable screw terminal connector, and SN75LBC184P limited slew rate transceivers (1/2 unit load) with built-in transient protection.

The CAS24 is designed for office and/or industrial applications (non-isolated), and provides superior characteristics/features normally found only on more expensive units. The CAS24 can also be used as a flexible interface converter. A host/remote network can be constructed using only 3 units (One converter and two addressable nodes).
