Quatech QSC-100 - Manual

1 General Information The Quatech, Inc. QSC-100 provides four RS-232 asynchronous serial communication interfaces for IBM-compatible personal computer systems using the PCI expansion bus. TheQSC-100 uses Quatech's new Enhanced Serial Adapter design. Legacy serial port data rates arelimited to a maxi...

1.1 Features The standard QSC-100 implements each of its communication channels with a 16750 UART and uses standard line driver and receiver components. For improved performance andindustrial-grade reliability. 1.1.1 "IND" Option --- Surge Suppression Upgrade The "IND" upgrade provid...

2 Hardware Configuration The QSC-100 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. Jumpers J3-J6 a...

3 Hardware Installation 1. Turn off the power of the computer system in which the QSC-100 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-100 in any empty PCI e...

4 Address Map and Special Registers This chapter explains how the four UARTs and special registers are addressed, as well as the layout of those registers. This material will be of interest to programmers writing driversoftware for the QSC-100. 4.1 Base Address and Interrupt Level (IRQ) The base add...

4.4 Options Register The Options Register allows software to identify the QSC-100 as a Quatech Enhanced Serial Adapter. It also allows software to set the UART clock rate multiplier. Figure 8 showsthe structure of the Options Register. The powerup default of the Options Register is all bits zero. Cl...

5 Windows Configuration 5.1 Windows Millennium 1. After inserting the QSC 100 for the first time the "Add New Hardware Wizard" willbegin. Select "Search for the best driver for your device.". Check the "Removable media" and"Specify location" box. Click the "Next&#...

5. Again select the radio button for "Driver from disk provided by hardware manufacturer." Click the "OK" button to continue. 6. Another "Install From Disk" dialog box will pop up. The path should already be pointing to the Quatech CD. Click the "OK" button to continu...

2. Click the "Device Manager" tab located along the top of the System Properties box. This lists all hardware devices registered inside the Windows 95 registry. Additionalinformation is available on any of these devices by click on the device name and thenselecting the "Properties" b...

6 DOS and Other Operating Systems The QSC-100 is not a direct drop-in replacement for a legacy serial port because its base address and IRQ 3 (COM2), etc. Rather, the system BIOS assigns the address and the IRQ in aplug-and-play fashion at boot time. Software which is to use the QSC-100 must be able...

8 External Connections RS-232-C devices are classified by their function as either Data Terminal Equipment (DTE) or Data Communication Equipment (DCE). Generally, data terminal equipment isdefined as the communication source and data communication equipment is defined as the devicethat provides a co...

The QSC-100 is a DTE device which connects to peripheral equipment through a single female D-37 connector, or using the adapter cable, four male D-25 connectors. The standardserial port connections are listed in Figure 17. 7 35 7 12 7 26 7 3 GND 22 15 22 29 22 6 22 20 RI 8 34 8 11 8 25 8 2 DCD 6 17 ...
