New RS-422/485
Low Profile PCI Serial Adapter with Power on Connector
Now available, the SIO-485.LPCI is a low-cost
RS-422/485 low profile PCI serial adapter that can be field configured
for RS-422, four-wire RS-485, or two-wire RS-485 communications.
RS-485 network termination, critical to robust multi-drop communication,
is selectable via an on-board switch. Additionally, the board
features an industry standard connector that will accept +5V
or +12V from any standard PC power supply hard drive or floppy
connector. The supplied power is passed through to pin 9 of the
board’s connector. This allows easy connection to Sealevel
RS-485 SeaI/O
modules, RS-422/485 POS (Point of Sale) systems,
or any other real world device that expects power from the serial
connection.
The SIO-485.LPCI utilizes an Oxford 16C950 UART with 128-byte
FIFO, eight times larger than boards with 16C550 compatible UARTs,
and supports standard PC data rates with a top speed of 921.6K
bps. The larger buffer allows error free operation even in high-speed
serial applications, and the 16C950 UART supports features including
isochronous mode, 9-bit protocol, and a baud rate prescalar.

Sealevel Systems
Announces The First Internal USB Box Header to RS-232 Serial
Adapters
Sealevel Systems, Inc. has launched the first
internal USB to RS-232 serial adapters, available in both one-port
and two-port models. These devices are intended for mounting
directly to a PC's chassis, eliminating the need for external
converters and providing a clean, professional installation.
All models are USB bus powered, are capable of data rates to
460K bps, and install inside the computer in a spare bracket
location or in a DB-9 "punch-out".
The SeaLINK+232.PC single port serial adapter is available with
either a low profile PC bracket (Item# 2108) or standard PC bracket
(Item# 2108S) while the two-port model ships with a standard
PC bracket (Item# 2208). Sealevel includes a 14" cable (Item#
CA260) that connects the SeaLINK devices to most motherboard
USB box header connectors and uses only one USB port per serial
port. Other cable options are available on a custom basis.

Sealevel Application Notebook
Control Discrete I/O Through a Wireless Network!
SeaI/O M-series modules offer a variety of I/O configurations
and interface via RS-485 (Modbus/RTU). In many cases where
the host controller is not located near the I/O, long runs
of cabling are impractical. To facilitate wireless control
of the I/O, now Sealevel offers three RF serial modem choices
for the host connection and an RF to RS-485 serial modem to
interface SeaI/O devices.
Sample configuration
Use
a USB wireless RF serial modem (Item# 9X9CU) to connect to a
USB port of the host PC, laptop, or mobile computer.
