1 General Information The Quatech, Inc. QSC(LP)-200/300 provides four RS-422 or RS-485 asynchronous serial communication interfaces for IBM-compatible personal computer systems using the PCI expansion bus. The QSC(LP)-200/300 uses Quatech's new Enhanced Serial Adapter design. Legacy serial port data rates are limited to a maximum of 115,200 bi[...]

2 Hardware Configuration The QSC(LP)-200/300 is automatically configured at boot time by the computer's BIOS or operating system. There are no required switches or jumpers to set for installation. This chapter lists a number of optional jumper settings that control various hardware features. These jumpers, located in a row along the top of the[...]

2.1.3 Force High-Speed UART Clock (X8, pins 17 and 18) This jumper forces an increase of the UART input clock frequency by a factor of eight. This feature can allow legacy software to use baud rates above 115,200 bits per second. It is also useful if the serial port device driver does not directly support setting the higher baud rates through the O[...]

3 Hardware Installation 1. Turn off the power of the computer system in which the QSC(LP)-200/300 is to be installed. 2. Remove the system cover according to the instructions provided by the computer manufacturer. 3. Make any desired optional jumper setting changes. 4. Install the QSC(LP)-200/300 in any empty PCI expansion slot. The board should be[...]

4.4 Windows 1995 Windows 95 maintains a registry of all known hardware installed in your computer. Inside this hardware registry Windows 95 keeps track of all of your system resources, such as I/O locations, IRQ levels, and DMA channels. The "Add New Hardware Wizard" utility in Windows 95 was designed to add new hardware and update this r[...]

NOTE : You may be able to skip this step if you are certain that your system has the latest version of these files installed. If you do not have your Windows 95 install disks immediately available, click "OK" anyway. A dialog box appears with an option to Skip the files. Click the Skip button and the files will not be installed. This is a[...]

4.6 Viewing Resources with Device Manager This discussion applies equally to Windows 95/98/ME and 2000/XP. Windows maintains a registry of all known hardware installed within the computer.

The X8 clock mode locks the ports hardware clock at eight times the standard rate. The baud rate the port runs at will always be eight times the rate requested by the application. This mode is useful for legacy applications which cannot request baud rates over 115.200. 921,600 X8 The X4 clock mode locks the ports hardware clock at four times the st[...]

Receivers are always enabled. In a Half Duplex mode, you will receive what you transmit (sometimes called echo). Always Receive Receive Control RTS routed to CTS, AUXIN routed to RCLK, and TCLK routed to AUXOUT. Used to connect ports transmitting at different baud rates. In order to function, all ports must have and use this feature. Clocks RTS rou[...]

Hardware automatically enables the transmitters when transmitting. Transmitters will turn off three bit-times after the last stop bit of the last character, regardless of baud rate. Used in two-wire communication. Auto Toggle DTR is set to enable the transmitters. Used in two-wire communication Half Duplex using DTR RTS is set to enable the transmi[...]
