Configuring the Serial Card

Once the Serial Card has been inserted, the PCMCIA socket must be configured for serial port operation. All PCMCIA input/output devices must be configured by software before they can be used. This configuring/enabling process must be repeated (that is, the enabling program must be run again) whenever the Card is powered off, then on again. A PCMCIA Serial Card will be powered off when the user removes it from the laptop and then re- inserts it. It may also be powered off, when the laptop goes into a "sleep" mode to conserve power.

There are two kinds of PCMCIA enabling software: Card and Socket Services, and Point Enablers. You must choose which software enabling method you will use to activate your Serial Card. Each method has its advantages and disadvantages. (See Card and Socket Service Users section or Point Enabler Users section for more information.)

Most laptops and desktops, that come equipped with PCMCIA slots, come with Card and Socket Services (CSS) software. This software manages the PCMCIA ports. If Card and Socket Services are running on your machine, your Serial Card will be set up and configured for you automatically when you insert the card into the PCMCIA slot. This is usually the easiest and best way to configure your Card. In most cases all you will need to do is plug in your Serial Card and access the assigned COM port. (Refer to your PC documentation for information concerning the Card and Socket Services provided with your system.)

Software Setup

Once your card is configured, it can be accessed through your application software by choosing the appropriate COM port. (Refer to the users manual associated with the software you are using for information on how to assign COM ports.)

Card and Socket Service Users

Card and Socket Services is a set of programs which are installed so that they are executed when the laptop is turned on. The Card and Socket Service programs then stay resident - they remain in memory all of the time. Card and Socket Services are designed to detect when a PCMCIA device has been inserted or powered off and then it automatically re-enables the device. This allows "hot swapping" - you can pull a PCMCIA card out and put in a different one and the new card is automatically enabled. Card and Socket Services also "know" how to enable a variety of devices from different manufacturers and attempt to prevent all conflicts between different PCMCIA cards.

This transition is essential for extending communication distances, allowing for transmission over significantly longer cables without degradation of the signal. While standard RS-232 communication is typically limited to 50 feet, the 232HSPCC reduces susceptibility to noise and enables distances of up to 4000 feet, making it ideal for factory automation, remote monitoring, and SCADA systems.

One of the standout features of the 232HSPCC is its robust design. This device is built to withstand harsh environmental conditions, ensuring reliable performance in areas with high levels of electromagnetic interference. It operates efficiently over a wide temperature range, accommodating diverse application settings while maintaining stability.

The 232HSPCC supports data rates of up to 115.2 kbps, ensuring high-speed communication that meets the demands of modern industrial networks. Its compatibility with various protocols adds to its flexibility, allowing it to be integrated seamlessly with existing systems. With its simple dip-switch configuration and automatic RTS/CTS handshaking, setup is straightforward, reducing downtime during implementation.

Additionally, this device features built-in isolation, which protects connected devices from voltage spikes and surges, thereby enhancing reliability and longevity. The 232HSPCC is also equipped with diagnostic LED indicators that provide real-time feedback on the status of communication and power, facilitating easier troubleshooting.

The compact design of the 232HSPCC allows for easy installation in confined spaces, while its sturdy housing provides durability and protection. This makes it suitable for both panel mounting and standalone applications.

In summary, B&B Electronics 232HSPCC is a powerful, versatile, and reliable solution for serial communication needs. Its ability to convert RS-232 to RS-422/485, combined with robust environmental resilience, high data rates, and built-in isolation, makes it an invaluable tool for professionals seeking efficiency and reliability in their operations.
