-
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
General Description:
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).
Need something special? Please contact us. We have additional isolated and non-isolated converters, repeaters, and repeater hubs. Units are generally stock to 2-3 business days for shipment. We design and manufacturer our entire product line, and offer technical support for our units, and can offer system recommendations for your application. Please give us a call: 513-874-4796
