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