12 Xtreme/104 Installation Overview
Before you begin, take a moment to ensure your package includes the components shipped with your product. These components should include:
One Xtreme/104 adapter One CD containing software and documentation DB-9 male fan-out cable or DB9 male cables (optional)
If any of these components are missing, contact Connect Tech (see more Contact Details) or your reseller.
There are three stages to installing your Xtreme/104:
1. Hardware Configuration
Interrupts and Memory selection will be set by the host computer‟s BIOS. This section outlines jumper settings and the ID selection process.
2. Hardware Installation
Installation involves the physical connection of the Xtreme/104-Plus or Xtreme/104 Express within your computer‟s PC/104-Plus stack. (Please note that you should configure any jumper settings, such as ID or electrical interface, if required, prior to installing the board.)
3. Software/driver installation
Load the appropriate driver for your Operating System, as found on the accompanying CD. Installation guides are also available on the CD to aid you in this process.
13 Hardware Installation
13.1 ESD Warning
Electronic components and circuits are sensitive to ElectroStatic Discharge (ESD). When handling any circuit boards including Connect Tech PC/104 boards, 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.

14 Hardware Configuration
14.1 Interrupts and Memory Address Selection
Xtreme/104 boards are PCI and PCI Express cards, so the host computer‟s BIOS or Operating System will automatically set interrupts and memory addresses when you reboot after installation.
14.2 Xtreme/104 Plus and Xtreme/PCI-104 ID Selection
Up to four PC/104-Plus or PCI-104 boards can reside within a single PC/104 module stack. Each card within the stack must have a unique ID ranging from zero to three.
(this section does not apply to PCIe/104 cards )
Depending on the model of your Xtreme/104-Plus adapter, you will be required to set either a pair of jumpers or a rotary switch to specify where your card is located within the stack. (Ensure that no two boards share an ID number.)
In systems designed prior to the PC/104-Plus 2.0 specification, the fourth ID was reserved for target only devices and did not support bus mastering. Since the Xtreme/104-Plus is not a bus mastering device, we would recommend an assignment of ID 3. This leaves three of the IDs in the PC/104-Plus stack available for bus mastering devices.
In systems designed post PC/104-Plus 2.0 specification, all four IDs support bus mastering, so there is no advantage to setting the Xtreme/104-Plus ID to 3. Regardless of which PC/104-Plus specification version the system is using, , the Xtreme/104-Plus will work with any ID selected as long as no other device in the system is using the same ID.
14.2.1 Xtreme/104 Plus ID Selection Using the Rotary Switch
If your Xtreme/104-Plus or Xtreme/104-Plus Opto is equipped with a rotary switch, turn the knob on the switch so that the arrow points at the ID you would like to use. (See Figure 6 for the location of the rotary switch on the board). Use the following settings to set your adapter‟s location (or ID) within the stack:

14.2.2 Xtreme/104 Plus and /PCI-104 ID Selection Using the Jumper Block
If your Xtreme/104-Plus or Xtreme/PCI-104 card is equipped with a jumper block for ID
selection, set your board‟s location by changing jumper positions. Figure 7 depicts the jumper settings required for each ID.
The jumpers remain unpopulated for an ID of zero. Populate the left jumper for an ID of one, the right jumper for an ID of two or populate both for an ID of three.

15 Electrical Interfaces Xtreme/104 Plus and Express
(RS-232/422/485 and RS-423 Models)
15.1 RS-232 Electrical Interface
This is the default setting for the interface selectable Xtreme/104-Plus and Xtreme/104-Plus Opto. To operate a port in RS-232 mode, no jumpers are set on the corresponding jumper block.
15.2 RS-422/485 Electrical Interface
Xtreme/104 Express, Xtreme/104-Plus and Xtreme/104-Plus Opto RS-232/422/485 adapters support three modes of RS-422/485 communication, as outlined below. (See Figure 8 to see examples of jumper settings.)
15.2.1 Full Duplex 4-Wire Mode
In this mode, TxD+/- and 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. This is sometimes called RS-422 mode.
15.2.2 Half Duplex 2-Wire Mode
In Half Duplex 2-wire mode during transmission the TxD+/- line driver is enabled and the RxD+/- is disabled. When the not transmitting, the TxD+/- is disabled and the RxD+/- is enabled. The TxD+/- is disabled by tri-stating the output driver pins.
This mode is used in both point-to-point 2-wire connections and in multi-drop 2-wire bus type connections. Special software setup is required so that the Xtreme/104 hardware automatically performs the TxD and RxD enabled and disabling.
See the Driver Software Configuration section for software setup.
15.2.3 Multi-drop 4-Wire Mode
In this mode the TxD+/- line driver is enabled only when data is transmitted and RxD+/- is enabled all of the time. This mode is used in multi-drop 4-wire connections. This mode is also called “Multi-drop” slave.
See the Driver Software Configuration section for software setup.
15.2.4 Line Bias and Termination
The RS-422/485 transceivers, both transmit and receive can be optionally biased to produce a line level mark condition through jumper selectable resistors. These options are typically used in multi-drop 4-wire and 2-wire connections.
The RxD+/- features a combined Bias and Termination network.
The TxD+/- feature a single Termination resistor.
See the Jumper Block settings in the next section for more details.

15.3.3 Jumper Details
RS-485 Selection: Install this jumper to configure a port for RS-422/485 mode. If the jumper is not installed, the port will function in RS-232 mode.
TxD Control: Install this jumper to only enable the RS-485 transmitter when sending data. This mode is useful for half-duplex operation when only one device is allowed to send data at a time. If the jumper is not installed, the transmitter will always drive the line to an idle state when not sending data.
RxD Control: Install this jumper to enable the RS-485 receiver only when NOT transmitting data. This is useful for half-duplex operation to prevent the transmitting device from receiving its own data as it sends. If this jumper is not installed, the receiver is always enabled and ready to receive data.
RxD ± Termination/Bias: Install this pair of jumpers to enable a 150 ohm terminator across the RxD+ and RxD- pins for the corresponding port. A biasing network is also enabled that drives the receiver to an inactive or safe mode. The receiver can still receive data from another device and the biasing helps to prevent the reception of data generated by noise on the transmission line. The two jumpers for RxD termination/bias must be installed and removed as a pair.
TxD ± Termination: Install this jumper to enable a 150 ohm resistor across the TxD+ and TxD­pins of the corresponding port.
Important Port Numbering Note for some Xtreme/104 Plus models:
Due to differences between the quad and octal UARTS, the port numbering for eight port models differs from the numbering for four port models.
Jumper blocks JA through JD control ports 1 through 4, respectively, on four port models.
On eight port models, jumper blocks JA through JD control the odd numbered ports and JE through JH control the even numbered ports, as follows: JA = Port 1, JB = Port 3, JC = Port 5, JD = Port 7 JE = Port 2, JF = Port 4, JG = Port 6, JH = Port 8.
Note: this does not apply to Xtreme/104 Express and Xtreme/104 Plus 16 port models
Half Duplex and 4-wire Multi-drop modes require you to select the appropriate
mode via software. Please refer to the readme.txt files found in the appropriate directories on the Xtreme/104-Plus/Express CD.

15.4 Power-on RS485 Tri-state for multidrop networks.
Xtreme/104- Opto models offer a power-on tri-state feature to ensure glitch-free power-up on multi-drop networks. When enabled, the Xtreme/104- Opto will hold the RS-485 transmitter in tri-state at power up. This feature is available on ports configured as RS-485 half duplex or RS­485 4-wire multi-drop.
Note: Enabling this feature on ports configured in RS-232 or RS-422 (RS-485 full duplex) modes will alter the operation of the RTS signal.
15.4.1 Xtreme/104-Plus Opto and Xtreme/104 Express Opto models:
Jumper J1 (Xtreme/104 Plus) and J19 (Xtreme/104 Express) control the power-on tri­state functionality. Install a jumper on the first location of J1 or J19, and configure Port 1 in RS-485 half duplex or multi-drop slave in order to tri-state Port 1 at power-on; install a jumper on the second position of J1 to control Port 2, etc. Ports will not come out of tri­state until the driver has loaded and transmission begins on the associated port.
Though J1 is a five position jumper, only the first four have connections to the ports on the card. The fifth has no function.
15.4.2 16 Port Models
Jumper G485 in J18 controls the power-on tri-state functionality. Install a jumper on this jumper to enable the Power on Tri-State function. This is a single jumper that applies to all ports.

16 Electrical Interfaces (RS-232/422/485/TTL Models)
16.1 RS-232/TTL Electrical Interface
The following control signals are available to ports configured for RS-232 and TTL mode: TxD, RxD, RTS, CTS, RI, DTR, DSR, DCD, SG (Signal Ground) and +5V. See Figure 3 for the location of Px1 RS-232/TTL port headers. See Figure 13 for information on configuring ports for RS-232 or TTL mode. (Note: Current draw on +5V pins of all ports must not exceed 1 Amp).
16.2 RS-422/485 Electrical Interface
In this mode, the port will communicate in RS-422 and RS-485 full duplex using the vertical Px2 headers. (See Figure 3 for the location of Px2 headers). The following control signals are available: TxD+/, RxD+/ and SR (Signal Reference). See Figure 13 for information on configuring ports for RS-422/485 mode.
16.3 Jumper Block Settings
The following jumper blocks correspond to the following ports: JA = Port 1 JE = Port 5 JB = Port 2 JF = Port 6 JC = Port 3 JG = Port 7 JD = Port 4 JH = Port 8
The pin functions are outlined in the following diagram:
Figure 12: Examples of Various Jumper Block Settings for RS-232/422/485/TTL Models
In the example in Figure 2, port 1 (JA) is configured for RS-422/485 full duplex, port 2 (JB) is configured for RS-232, port 3 (JC) is configured for TTL, and ports 4 to 8 (JD to JH) are disabled.
When all jumpers are removed, the corresponding ports are completely disabled. The UART will receive no data from these ports, even if an external source is driving the headers.
Note: There are eight solder jumpers on the back of the board that correspond to the vertical (Px2) headers on the front of the board. (See Figure 3 for location of Px2 headers). If necessary, you can ensure TxD+/- pins on specified vertical headers

17 Electrical Interfaces Xtreme/PCI-104 12 Port Opto
17.1 I/O Port Power for the Xtreme/PCI-104 Opto 12 Port
Jumpers J2A, J2B and J2C provide the ability to power on or off the I/O section of a port in groups of four. Removing the jumpers will remove power from the DC-DC converter and all components in the isolated section of the product.
This mode can be used in cases where power is in short supply and the group of ports is unused.
The factory default is to have all three jumpers installed to enable all three banks of ports.
Note about Fusing: Each bank is protected by a resettable fuse from damage due to circuit failure or overload. To reset the fuse, the power should be removed for a minimum of one minute.
17.2 Line Modes
17.2.1 Low Power Shutdown
This is the default mode when no mode configuration jumpers are installed. In this mode the SP336 line transceiver is shutdown and the I/O section port consumes a minimum of current. The current reduction is as much as 50ma for shutting down of a RS232 port and 70mA for shutting down a RS485 port.
17.2.2 RS-232 Electrical Interface
Standard RS-232 mode.
17.2.3 Full Duplex 4-Wire RS485
In this mode, TxD+/- and 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, where long distances are required.
17.2.4 Multi-drop 4-WireRS485
In this mode the TxD+/- line driver is enabled only when data is transmitted and RxD+/- is enabled all of the time. This mode is typically used in multi-drop 4-wire connections.
See the Driver Software Configuration section for software setup.
17.2.5 Half Duplex 2-Wire RS485
In Half Duplex mode the TxD+/- line driver is enabled only when data is transmitted, whereas, the 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.
See the Driver Software Configuration section for software setup.

17.4 Bias and Termination Resistors
Revision 0.09
The (B&T) Bias and Termination resistors are use in RS485 communications. All other modes these jumpers should be removed.
The B&T resistors are selected using jumpers Jx.1E/Jx.1F and Jx.2A/Jx.2B.
RXD and TXD/RXD Termination/Bias: Install this pair of jumpers to enable a 150 ohm terminator across the RxD+ and RxD- or TxD+ and TxD- pins for the corresponding port. A biasing network is also enabled that drives the receiver to an inactive or safe mode. The receiver can still receive data from another device and the biasing helps to prevent the reception of data generated by noise on the transmission line. The two jumpers for the termination/bias must be installed and removed as a pair.
Bias and Termination Notes:
For 2-wire and 4-wire multidrop wiring networks the B&T resistors are only installed when the Xtreme/PCI-104 12 Port Opto is the first or last device in the wiring network.
