RSCOM2A: Async RS232 to RS485 / RS422 fast automatic bidirectional converter with removable connectors and LED indicators w/ 12V Power Supply & DB9F Adapter w/ 7ft. Cable in Boxed Enclosure
Fast auto TX-enable RS485 (2-wire, half-duplex) or RS485/RS422 (4-wire, full-duplex, fixed enable or auto TX-enable) for multi-drop, and/or point-to-point networks
Fast auto TX-enable RS232 to RS485 bidirectional interface converter for 2-wire, half-duplex communications, or fixed/auto TX-enable RS232 to RS485/RS422 bidirectional interface converter for 4-wire, full-duplex, point-to-point or multi-drop communications, at distances up to 4000 ft. and data rates up to 115.2Kbps
The RSCOM2A is a fast Async bi-directional RS232 ↔ 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 can also be used in 4-wire RS485/RS422 application (point-to-point or multi-drop, full-duplex). The unit has jumpers for bias, termination, RS232 DTE/DCE selection, and operating mode settings. The unit has edge mounted LED indicators, a removable screw terminal connector, and uses SN75LBC184P limited slew rate transceivers (1/2 unit load) with built-in transient protection.
The RSCOM2A is designed for office and/or industrial applications (non-isolated), and provides superior characteristics/features normally found only on more expensive units.
