TurboPort/RA1 & TurboPort/RA2 Hardware Instruction SheetThe TurboPort/RA1 and the TurboPort/RA2 have two modes of operation: standard and enhanced. In standard mode, a TurboPort port can operate up to 115.2K baud as a standard COM1 through COM4 serial port with 32 byte buffers. If you operate the TurboPort in standard mode you will not need to install any software drivers or utilities, but can use the board as configured at the factory for most operating environments. If you wish to take advantage of any of the TurboPorts higher performance capabilities (up to 460.8K baud, automatic data flow control, or the use of nonstandard interrupts), then you will need to operate the board in the enhanced mode. Depending on the operating environment of your system, either a software utility or one of the device drivers that are supplied with the board will allow the TurboPort to use any or all of the features of enhanced mode. The following table shows which utility or device driver must be used for the particular operating environment you are using. Operating System Utility Driver DOS Turboport DOS Utility None Windows 3.1 None Windows 3.1 Driver WFW 3.11 None WFW 3.11 Driver Netware Client Turboport Dos Utility None OS/2 None OS/2 Device Driver Windows 95 None Windows 95 Driver Windows NT None Windows NT Driver Step 7 of this instruction sheet describes where to find installation instructions for these software utilities and drivers. Step 5 of this instruction sheet describes how to configure the TurboPort to operate at the enhanced mode baud rates without the use of a driver or a utility. You may need to make some adjustments to the DIP switches on the TurboPort/RA1 or TurboPort/RA2 before installing the board in your host PC. CAUTION The TurboPort/RA1 and the TurboPort/RA2 contain several components that can be permanently damaged if the boards are handled improperly. To avoid accidental damage, hold the boards only by their edges and follow these recommendations: Before handling the boards, touch a grounded object to discharge any static electricity that has built up on your body. Never insert or remove the boards while power is applied to the computer. Once the computer power switch is shut off, wait at least 10 seconds for the power supply to discharge before inserting or removing the boards. ³ ³ ÚÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ¿ ÚÄÄÄÄÄÄÄÄÄÄÄ¿ ÃÄÄÄÄÄÄÄÄÄÄÁÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÁÄÁÄÄÄÄÄÄÄÄÄÄÄÁÄÄÄÄÄÄÄÄ¿ ÚÄ´ ³ ³ ³ Port 2 Ú12345678¿ ³ ³ ³ Connector ³ ³ ³ ÀÄ´ ÀÄÄÄÄÄÄÄÄÙ ³ ³ ³ ³ ³ ÚÄ´ ³ ³ ³ Port 1 Ú12345678¿ ³ ³ ³ Connector ³ ³ ³ ÀÄ´ ÀÄÄÄÄÄÄÄÄÙ ³ ³ ³ ÃÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÙ ³ ÄÄÙ NOTES You can not set both ports of a TurboPort/RA2 to either IRQ3 or to IRQ4 with this interrupt assignment mode. The only way for both ports to share an interrupt is to assign a single IRQX line to both ports. See step 2b for instructions for doing this. If your system has built-in serial ports enabled for COM 1 and COM 2 which use IRQ3 and IRQ4, you may not be able to use this interrupt assignment mode for the TurboPort. Instead, follow the instructions in step 2b to assign an IRQX other than IRQ3 or IRQ4 to the TurboPort ports. When you have set the switches on SW1, then make sure all the switches on DIP switch SW2 are set to OFF, as illustrated for the default setting in the table in step 3. This interrupt assignment mode will work for most Windows, NetWare, and other applications. If you wish to select a single IRQX for a TurboPort/RA1 or for a TurboPort/RA2, the following table shows the address and interrupt selections for port 1 that are determined by the positions of switches 1, 2, 3, and 4 of DIP switch SW1. Com Port Address Interupt SW1 Pos 1 SW1 Pos 2 SW1 Pos 3 SW1 Pos 4 Selected Selected None N/A NONE N/A N/A N/A OFF COM 1 3F8-3FF IRQ4 ON ON ON ON COM 2 2F8-2FF IRQ3 OFF ON ON ON COM 3* 3E8-3EF IRQ4 ON ON OFF ON COM 4 2E8-2EF IRQ3 OFF OFF ON ON COM 1 3F8-3FF IRQX ON ON OFF ON COM 2 2F8-2FF IRQX OFF ON OFF ON COM 3 3E8-3EF IRQX ON OFF OFF ON COM 4 2E8-2EF IRQX OFF OFF OFF ON If you wish to select a single IRQX for a TurboPort/RA2, the following table shows the address and interrupt selections for port 2 that are determined by the positions of switches 5, 6, 7, and 8 of DIP switch SW1. (Note that switches 5 through 8 are not used for the TurboPort/RA1.) When you have set the switches on SW1, then set the switches on DIP switch SW2 to enable the desired IRQ signal for IRQX. Com Port Address Interupt SW1 Pos 5 SW1 Pos 6 SW1 Pos 7 SW1 Pos 8 Selected Selected None N/A NONE N/A N/A N/A OFF COM 1 3F8-3FF IRQ4 ON ON ON ON COM 2 2F8-2FF IRQ3 OFF ON ON ON COM 3 3E8-3EF IRQ4 ON OFF ON ON COM 4* 2E8-2EF IRQ3 OFF OFF ON ON COM 1 3F8-3FF IRQX ON ON OFF ON COM 2 2F8-2FF IRQX OFF ON OFF ON COM 3 3E8-3EF IRQX ON OFF OFF ON COM 4 2E8-2EF IRQX OFF OFF OFF ON CAUTION To prevent interrupt contention, make sure that no more than one position on SW2 is set to ON before you install and operate a TurboPort board. You can use both modes of interrupt assignment for a TurboPort/RA2 by setting SW1 position 3 to ON and SW1 position 7 to OFF (or vice versa). You then set DIP switch SW2 to assign an IRQ to the port whose SW1 switch you set to OFF. Note, however, that you can not use the same IRQ (either 3 or 4) that was assigned to the port whose SW1 switch you set to ON.4 Software-Select is the default mode for determining baud rate operation for the TurboPort. In this mode, the TurboPort will default to standard baud rates (75 to 115.2K) at power-up time, but fast baud rates (up to 460.8K) can be selected with the software (utility or driver) supplied with the controller. However, you can alternatively hard-wire the TurboPort/RA1 or port 1 of a TurboPort/RA2 to operate at either standard or fast baud rates by changing the jumper connection at jumper JMP1 from the Software-Select mode of operation. Jumper JMP2 determines the mode of operation for port 2 of a TurboPort/RA2.

When the TurboPort/RA1 or TurboPort/RA2 is properly configured, it may be installed in the computer. Refer to the computer manual for installation instructions. 6 Connect one serial peripheral device to the TurboPort/RA1 or up to two serial peripheral devices to the TurboPort/RA2.
