Description
The PCMCIA-232 is a PC-based Serial interface device, specifically designed for applications requiring RS232 and RS485 connections. It features a 1-port configuration, ensuring a straightforward and efficient serial communication setup. The device is identified by its part numbers, 183884B-01 (Primary) and 777379-01, making it easily recognizable for procurement and support purposes.
This serial interface device is compatible with a 1-connector DB-9 interface cable, which connects via a DB-9 male connector. This compatibility ensures a wide range of applications can be supported, from industrial equipment to networking systems. The PCMCIA-232 operates as a Type II PC Card, drawing power directly from the PCMCIA slot, which eliminates the need for an external power supply. This feature significantly enhances its ease of use and integration into existing systems.
One of the key technical specifications of the PCMCIA-232 is its maximum communication distance of up to 50 ft, combined with a maximum transfer rate of up to 921.6 kb/s. These capabilities ensure that the device can handle demanding serial communication tasks with ease. Moreover, it has a current requirement of 40 mA at +5 VDC, making it an energy-efficient option for many applications.
The device incorporates 16550-compatible receiver/transmitter functionality along with 16 B FIFO buffers for both the transmitter and receiver. This setup guarantees smooth and reliable data transmission, even in high-traffic environments. Despite its advanced features, the PCMCIA-232 has been announced as obsolete by National Instruments. However, it remains available for purchase and repairs through Apex Waves, ensuring continued support for users who rely on this critical piece of hardware for their serial communication needs.
