Introduction
The Sealevel Ultra 530.LPCIe (Item# 7106e) is a PCI Express 2.0 Gen 1 compliant interface adapter with
one field selectable RS-232/422/485/530 asynchronous serial port supporting data rates up to 921.6K bps
for industrial automation and control applications.
Configure the serial port as RS232 for standard serial COM port requirements. Choose the RS-422 mode
for long distance device connections up to 4000ft. where noise immunity and high data integrity are
essential. Select RS-485 and capture data from multiple peripherals in an RS485 multi-drop network. Up to
31 RS-485 devices can be connected to each port to automate your data collection.
In RS-485 mode, the transmitter is automatically enabled in hardware, eliminating the need for application
software control. This allows the 7106e to be used with standard serial communications applications and
removes the risk of bus contention and data corruption. In RS-232 mode, all modem control signals are
implemented for maximum compatibility with a wide range of serial peripherals. The Sealevel SeaCOM
software driver and utilities make installation and operation easy in Windows 7/8.1/10 and Linux operating
systems.
The Ultra 530.LPCIe ships with a Low Profile PCIe bracket that will only work in a Low Profile PCIe slot. If
you need a standard size PCIe bracket, please order Item# 7106eS. The product is RoHS compliant and
meets the requirements of RoHS (2011/65/EU) directive.
