Hardware Installation
Installing the BlueStorm/LP into your system
Turn the power off to your computer and open it to expose the expansion slots (consult your
system’s documentation for more information about this procedure).
Choose an available PCI expansion slot, remove the expansion slot cover and insert the
BlueStorm/LP adapter, pushing down gently until the board seats fully in the slot. Secure the
BlueStorm/LP to the computer chassis.
Hardware Configuration
Interrupts and Memory Address Selection
The BlueStorm/LP is a PCI card, so the host computer’s BIOS will automatically set interrupts
and memory addresses when you reboot after installation.
Electrical Interfaces
RS-422/485 Electrical Interface
The BlueStorm/LP RS-232/422/485 adapter supports three modes of RS-422/485
communication, as outlined below. (See
Figure 1 and Figure 2 for jumper block locations.)
Full Duplex Mode
In this mode, TxD+/- & RxD+/- are being driven to a known level all the time. This mode is
typically used in point-to-point situations much like RS-232. It is the default setting.
Half Duplex Mode
In this mode the TxD+/- line driver is enabled only when data is transmitted and RxD+/- is
disabled when data is being transmitted. This mode is typically used in either point-to-point 2-
wire connections OR in multi-drop 2-wire bus connections. This mode requires software setup
in
Control Panel – System – Hardware – Device Manager – Ports – CTI PCI UART. Click on Advanced under
Port Settings after the driver is installed. (See Multi-drop Slave below)
