Roalan Ltd is the source for professional computer adapter products.

Dear Sirs
For the past 18 months I have made an average of two to three online
purchases every week from a large number of suppliers and I am writing to say that your Company has provided the most efficient service I have ever
received.
The order was placed in the early hours of Friday morning on July 4th with
the item scheduled for delivery by 9.30 am on Saturday July 5th. The
delivery company InterlinkExpress fulfilled their commitment and the PCI
board that you supplied was installed by 9.35 am.
It was a delight to do business with your Company.
Thank you.

PCI-X 3.3v 3.3 volt serial

Attach up to 64 serial devices to a single bus slot in your server

These intelligent serial I/O adapters use less than 1% system load so servers won't slow down as you run more applications, attach more devices or service more users. They do not use an interrupt (IRQ)

Expandable Serial RS232 Communication Adapters provide an easy, manageable and cost-effective way to attach up to 128 serial devices to a single PCI/PCI-X 64 bit 3.3 volt (3.3V) or 5V bus slot in your server. These Expandable adapters are available in 64 and 128-port models. For local or clustered connections, mix and match any combination of port modules, RS-232 or RS-422 with either DB-25 or RJ-45 connectors. You can also daisy chain Port Modules to your server via a Host Controller.

These Expandable Serial Adapters provide an easy, manageable and cost-effective way to attach up to 64  serial devices to a single bus slot in your server.

Universal adapters support a 3.3Volt (3.3V PCI-X 64 bit) or 5V PCI bus
