RocketPort Plus

A Faster PCI Serial Card--921 Kbps Across All Ports

While most serial cards run at or around 230 Kbps on each port, Comtrol's RocketPort Plus is different. It runs at speeds up to 921 Kbps simultaneously across all eight ports. The installation is easy because there is no shared memory to configure. The RocketPort Plus serial controller card quickly installs into the PCI slot of a personal computer. And once installed, the port looks like standard COM ports. The RocketPort Plus uses two 44 MHz processors specifically designed to process asynchronous serial communications in order to maximize performance and eliminate bottlenecks. This sets the RocketPort Plus card apart from all other cards of its kind. That means a 44 MHz processor for each of the four ports. So, the RocketPort Plus is not only faster, but reliable.

Fully Integrated ASICs

Other serial cards use numerous components to accomplish their tasks. Each of these components and its mounting on the card means an increased risk of failure.

The RocketPort Plus multiport serial card is equipped with fully integrated ASICs (Application Specific Integrated Circuits). Comtrol's ASIC was designed to serve functions that usually require multiple components. Integration not only reduces the component count by 80%, which means a significantly reduced risk of failure, but also reduces RocketPort Plus' power consumption considerably. The result is the most reliable and economical serial port card available.

Unique Transguard™ Surge Protection on All Ports

Most multiport cards are not able to withstand electrostatic discharge and power surges up to 25 Kv ESD. Comtrol's RocketPort Plus is designed to withstand such conditions. The RocketPort Plus power surge/ESD protection is an advanced feature not commonly found on other 921 Kbps cards.

Larger Transmit and Receive FIFOs Speed Data Transfer

The large FIFOs on the RockePort Plus ensure sustained transfer rates by buffering data when the CPU is busy. Many serial cards have very small FIFOs, or buffers, used for transmitting and receiving data. With smaller buffers, a card must stop each time the buffer fills and wait for the data to clear. This continual starting and stopping increases the load on the CPU and reduces the overall performance of the card. The large buffers help ensure consistent, high throughput even on heavily loaded servers.

Maximized Throughput, Minimized Cost

The ASIC design and larger FIFO buffers, combined with two dedicated 44 MHz processors for each of the four ports, gives RocketPort Plus the power to sustain throughput at speeds of up to 921 Kbps on each port simultaneously. That's more throughput for a lower price than most conventional multiport serial cards!
