• Fast auto TX-enable Isolated Async RS232 ó RS485 (2-wire, half-duplex) interface converter, powered by PC ISA bus card slot.
• Isolated fast auto TX-enable RS232 to RS485 interface converter for 2-wire, half-duplex communications, multi-drop communications, at distances up to 4000 ft. and data rates up to 115.2Kbps. Internal ISA bus powered unit.
• Galvanic (Opto/Xformer) Isolation helps eliminate noise, and protects equipment from destructive transients found in industrial applications.
GENERAL DESCRIPTION and TYPICAL APPLICATIONS:
The IPC24 is a fast Async bi-directional RS232 to RS485 interface converter for 2-wire, half-duplex applications, with an automatic TX enable circuit, that will operate at data rates up to 115.2Kbps. The unit has jumpers for bias, termination, and loop-back-test/normal operation. The unit has two LED indicators for TX-RS485(RED) data/RX-RS485(GRN) data, two DB9F connectors, and built-in transient protection. Galvanic isolation between the RS232 and RS485 helps to eliminate a wide variety of problems encountered in industrial and/or real world applications.
The IPC24 is designed for office and/or industrial applications, and provides an internal conversion from RS232 ó RS485 by obtaining power form an ISA bus card slot on a PC mother board. By connecting a cable from an existing RS232 port a conversion is made to Isolated RS485 and is available from a DB9F connector at the rear of the computer. The IPC24 can be used in outdoor applications; however, many factors can affect reliable operations. Please call for additional information and/or peruse our Fiber Optic product line (compatible with our "copper" converters).
