Point Enabler Users

The main disadvantage of using Card and Socket Services are that they permanently occupy a certain amount of laptop or desktop memory, which could be used by other programs.

Most Card and Socket Service programs are loaded from the CONFIG.SYS file and use from 40K to 85K of memory space. If Card and Socket Services is running properly on your machine, then your Serial Card will be recognized and configured properly by simply inserting the card into one of the PCMCIA slots.

Point Enablers are programs that run, enable a specific device (such as your B&B Electronics Serial Card), and exit. Point Enabler commands are typically installed in the AUTOEXEC.BAT file so that they will be executed once each time the laptop or desktop is turned on. The advantage of a Point Enabler, is that it uses system memory only while it runs. The disadvantage is that when the PCMCIA device is powered off, the user must remember to execute the Point Enabler command to re-enable the Serial Card. Another disadvantage in using Point Enablers is that you need a different one for each manufacturer's PCMCIA device. One manufacturer's Point Enabler may conflict with another's Point Enabler. A Point Enabler program may also conflict with an already running Card and Socket Service program. It is best NOT to run a Point Enabler if Card and Socket Services have already been loaded on your PC.

Using the Point Enabler Program

B&B Electronics has supplied a Point Enabler program called ENABLE.EXE. To use this program perform the following:

1.Copy the file “ENABLE.EXE” from the supplied diskette onto your root directory. (Typing ENABLE /? on the command line will bring up a program help screen.)

2.Use a text editor to add the following line to your AUTOEXEC.BAT file:

ENABLE /com2 /sA /MD000

232HSPCC specifications

B&B Electronics 232HSPCC is a highly regarded serial communication device known for its efficiency and versatility. This product is especially recognized for facilitating reliable data transfer in various industrial applications, making it a favorite among engineers and technicians.

At the heart of the 232HSPCC is its ability to convert RS-232 signals to RS-422/485. 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.
