Chapter 2: Hardware Installation 2-1 Introduction Hardware installation involves configuration of the DFlex-4/104 adapter. The following sections detail how to change the field configurable parameters. The setting of these will depend on both the number of boards you are installing and the existing configuration of your system. Note: Please refer to Chapter 3: Software Installation for installation of your DFlex-4/104 board under certain operating systems.
2-2 Chapter 2: Hardware Installation Port Addresses Port addresses are configured with the DIP switch block SW1 situated near the PC/104 bus connector on the DFlex-4/104 adapter. DIP switches 1, 2, and 3 select a set of port addresses for the ports while DIP switch 6 enables or disables a specific status port address for that set of addresses. Please refer to Figure 4 for a description and location of the switch block, while Table 2 provides the switch settings for the various port address sets.
Chapter 2: Hardware Installation 2-3 Status Port Addresses Some operating system device drivers can utilize an Interrupt Status Port, for example Windows NT offers it as an option and for SCO Unix it is mandatory. This can improve your system’s efficiency. The DFlex-4/104 offers a status port and this port is enabled and disabled using DIP switch 6 on switch block SW1. When DIP switch 6 is in the on position the status port is enabled and when it is in the off position it is disabled.
2-4 Chapter 2: Hardware Installation Custom Port Addresses You can generate other port addresses by making changes to the PALs found on the DFlex-4/104 adapter. If you require specific port addresses not listed in Table 2 please contact the Connect Tech sales department for further information. 10 11 Port address switches 9/2 Figure 4: Port address (SW1) Status Port switch ON SW1 1 DFlex-4/104 User's Manual, ver. 0.

2-6 Chapter 2: Hardware Installation Interrupt Selection You can configure an interrupt request line (IRQ) with the jumper block J2 and DIP switches 4 and 5 on switch block SW1 situated near the PC/104 bus connector on the DFlex-4/104 adapter. Please refer to Figure 5 for a description and location of the jumper block J2 and switch block SW1.
Chapter 2: Hardware Installation 2-7 You are able to configure the DFlex-4/104 adapter for three different IRQ modes. ■ ■ ■ Mode 1 (one IRQ): all ports interrupting on one IRQ Mode 2 (two IRQs): odd ports (ports 1 and 3) interrupt on one IRQ and even ports (ports 2 and 4) interrupt on another IRQ Mode 3 (four IRQs): each port interrupts on it’s own interrupt Mode 1 (one IRQ) Mode 1 allows you to select one IRQ for all ports. This mode is recommended for most installations.
2-8 Chapter 2: Hardware Installation Examples: 1. The following example shows the settings on J2 and SW1 so that all ports will interrupt on the factory setting of IRQ 4. IRQ D B C A J2 IRQ jumper block 15 14 12 11 10 9/2 7 6 5 4 3 IRQ switches ON SW1 1 2 3 4 5 Port address switch block 6 Off 2. The following example shows the settings on J2 and SW1 so that all ports will interrupt on IRQ 10.
Chapter 2: Hardware Installation 2-9 Mode 2 (two IRQs) Mode 2 allows you to select one IRQ for ports 1 and 3, and another IRQ for ports 2 and 4. Please follow these steps to choose this mode: 1. 2. 3. 4. Choose an available IRQ for ports 1 and 3 and an available interrupt for ports 2 and 4 . Make sure that switch block SW1 has DIP switch 4 in the on position and DIP switch 5 in the off position.
2-10 Chapter 2: Hardware Installation Examples: 1. The following example shows the settings on J2 and SW1so that ports 1 and 3 will interrupt on IRQ 7 and ports 2 and 4 will interrupt on IRQ 12. IRQ D B IRQ jumper block J2 A C 15 14 12 11 10 9/2 7 6 5 4 3 IRQ switches ON SW1 Port address switch block 1 2 4 3 5 6 Off 2. The following example shows the settings on J2 and SW1so that ports 1 and 3 will interrupt on IRQ 10 and ports 2 and 4 will interrupt on IRQ 15.
Chapter 2: Hardware Installation 2-11 Mode 3 (four IRQs) Mode 3 allows you to select a unique IRQ for each port. Please follow these steps to choose this mode: 1. 2. 3. 4. 5. 6. 7. 8. Choose available and unique IRQs for ports 1, 2, 3 and 4. Make sure that switch block SW1 has DIP switch 4 in the off position and DIP switch 5 in the on position. Please take note of the two solid white lines just above jumper block J2. These lines mark the A, B, C and D portions of the corresponding row of jumper pins.
2-12 Chapter 2: Hardware Installation Examples: 1. The following example shows the settings on J2 and SW1so that port 1 interrupts on IRQ 5, port 2 interrupts on IRQ 7, port 3 interrupts on IRQ 10 and port 4 interupts on IRQ 15. IRQ D B IRQ jumper block J2 A C 15 14 12 11 10 9/2 7 6 5 4 3 IRQ switches ON SW1 Port address switch block 1 2 4 3 5 6 Off 2.
Chapter 2: Hardware Installation 2-13 The DFlex4/104 is capable of baud rates up to 460.8 kbps (4X oscillator) or 115.2 kbps (1X oscillator) depending on the position of jumper J1. If the jumper is in the off position (default) during a hardware reset, the maximum baud rate will be 115.2 kbps. However if the jumper is in the on position during a hardware reset the maximum baud rate will be 460.8 kbps. Please refer to Figure 6 for a description and location of the jumper block J1.
2-14 Chapter 2: Hardware Installation The purpose of the jumper is to provide compatability with device drivers that won't select the desired baud rates if the DFlex4/104 is set for 460.8 kbps. For example most serial drivers expect a maximum baud rate of 115.2 kbps (or a 1X oscillator), however if you set the DFlex4/104 at 460.8kbps (4X oscillator) then you have selected a baud rate that is FOUR TIMES FASTER! Please refer to Table 3 for a list of standard and extended baud rates for the DFlex-4/104.
Chapter 2: Hardware Installation 2-15 Serial Line Interface Modules (SLIM) The DFlex-4/104 adapter accepts interchangeable electrical line interfaces. These Serial Line Interface Modules (SLIM) provide the electrical interface for two asynchronous communication ports. If you order RS-232 or RS-232/Fast modules please refer to Appendix E: RS-232 Option for more technical information. If you order RS-485/422 modules please refer to Appendix F: RS-485/422 Option for more technical information.

Place the SLIM into the socket almost vertically (about a 75 degree angle), making sure to align it properly before inserting it into the socket.
Chapter 2: Hardware Installation 2-17 To remove a SLIM from its connector follow these steps: 1. 2. Using both hands, place your thumbs on the clips that hold the SLIM into the socket, and place your index fingers on the edge of the SLIM. Push outwards (with your thumbs) on the clips until you release the SLIM from the clips. Your index fingers can then raise the SLIM past the clips. You can then remove the SLIM from the DFlex-4/104 adapter.
2-18 Chapter 2: Hardware Installation SLIM compatibility Some of the standard SLIM modules cannot take advantage of the faster baud rates available with a DFlex-4/104 is set for 460.8 Kbps.

Chapter 4: Appendix H - 20mA Current Loop 4-27 Appendix H: 20mA Current Loop Option You may order DFlex-4/104 adapter with 20mA current loop Serial Line Interface Modules. The 20mA current loop electrical interface provides a reliable high speed serial link over long distances that offers superior noise immunity and multi-drop network connectivity. WARNING You must insert Serial Line Interface Modules into all of the SLIM sockets to attain the communications functionality of your DFlex-4/104 adapter.
4-28 Chapter 4: Appendix H - 20mA Current Loop 20mA Current Loop SLIM The 20mA current loop module provides optically isolated 20mA active or passive current loop interfaces for two ports. For each port there is an isolated receiver, an optically isolated transmitter and two 20mA current sources. See Figure 20 for the schematic of the 20mA current loop module. Note:. The current source uses a compliance voltage of 24 volts, and the transmitter will withstand a 27 volt drop.
Chapter 4: Appendix H - 20mA Current Loop 4-29 To implement a passive interface, wire the transmitter and the receiver, while leaving the current sources unconnected. An external current source is required to implement a passive interface. To implement an active interface, connect a 20mA current source in series with the transmitter and another 20mA current source in series with the receiver.

Chapter 4: Appendix H - 20mA Current Loop 4-31 Current Loop Cable Wiring You can wire DFlex-4/104 adapters with the 20mA Current Loop option in various ways to communicate with 20mA Current Loop peripherals. This section will descibe a few examples of current loop cabling schemes. Figure 21 describes a 4 wire cabling scheme between a port on the DFlex-4/104 adapter to another port on the DFlex-4/104 adapter.
