ESD Warning
Electronic components and circuits are sensitive to
ElectroStatic Discharge (ESD). When handling any circuit
board assemblies including Connect Tech COM Express
carrier assemblies, it is recommended that ESD safety
precautions be observed. ESD safe best practices include,
but are not limited to:
Leaving circuit boards in their antistatic packaging
until they are ready to be installed.
Using a grounded wrist strap when handling circuit
boards, at a minimum you should touch a grounded
metal object to dissipate any static charge that may be
present on you.
Only handling circuit boards in ESD safe areas, which
may include ESD floor and table mats, wrist strap
stations and ESD safe lab coats.
Avoiding handling circuit boards in carpeted areas.
Try to handle the board by the edges, avoiding contact
with components.

Detailed Feature Description
Port Mode Jumper Block Settings
Description
The following jumper block diagram depicts typical settings on an interface-selectable Xtreme/104-Express. (See
Figure 1 for location of jumper blocks.). Jumper blocks are labeled JA (Port1) to JH (Port8).
Jumper blocks appear on the board as follows. JA through JD are on one side of the board, and JE through JH are on
the other side of the board. The positions are A through G on each jumper block, as indicated here.
Figure 2: Jumper Clock Diagram
NOTE: You must configure your jumper block settings before installing the Xtreme/104-Express
board into your system.
Jumper positions A, B and C work together to establish the Line interface mode.

Electrical Interfaces Descriptions
RS-232 Electrical Interface
This is the default setting for the selectable interface of the Xtreme/104-Express. To operate a port in RS-232 mode,
no jumpers are installed on the corresponding jumper block.
RS-422/485 Electrical Interface
Xtreme/104-Express models offer three modes of RS-422/485 communication, as outlined here…
Full Duplex Mode
In this mode, TxD+/- signals are actively is being driven all the time. This mode is typically used in point-
to-point situations much like RS-232. It is the default setting for RS-422/485 mode.
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 Xtreme/104 PCI Express UART Serial Port.
Multi-drop Mode
In this mode the TxD+/- line Driver is enabled only when data is transmitted and RxD+/- is enabled all the
time. This mode is typically used in multi-drop 4-wire connections. This mode requires software setup in
Control Panel –System Properties –Hardware –Device Manager –Ports –CTI Xtreme/104 PCI Express
UART Serial Port.
Line Bias/Termination
The RS-422/485 transceivers can be configured to terminate and produce a line level mark condition on the
receiver, and/or terminate the transmitter. These options are enabled through on-board jumper selectable
resistors. These options are typically used in multi-drop 4-wire or half duplex 2-wire connections.
Tri-State Operation
Xtreme/104-Express models offer a power-on Tri-State option to ensure glitch-free network operation while the
system is powering up. If enabled (via JAJH, positon G), the Xtreme/104-Express will Tri-State the Transmitter
until the Driver opens the port. This operation is configurable for any port configured as RS-422/485, regardless of
the RS-422/485 mode selected.
Auto-485 Mode Jumper
Jumper location J2 has a position labeled “Auto-485” which, if installed, enables RS485 mode for all ports, at
power-up. This is useful for situations where there is no Software Driver to setup RS485 mode of operation.
