Chapter 2: Hardware Installation 2-1 Introduction Hardware installation involves configuration of the Echo adapter. Note: Please refer to Chapter 3: Software Installation for installation of your Echo board under certain operating systems. The following sections detail how to change the field configurable parameters. The setting of these will depend on the number of boards installed and the existing configuration of your PC.
2-2 Chapter 2: Hardware Installation Port Addresses You configure port addresses with DIP switches 1 to 5 on SW1. Switches 3 to 5 select a set of port addresses for the ports, while you can override the setting for port 1 and 2 with switch 1 and 2 respectively. When DIP switch 1 is on, then port 1 is COM1 at 3F8 hex. If DIP switch 2 is on then port 2 is COM2 at 2F8 hex. These settings will override the addresses specified by DIP switches 3, 4 and 5.
Chapter 2: Hardware Installation 2-3 Custom Port Addresses You can generate other port addresses by making changes to the programmable logic found on the Echo adapters. If you require specific port addresses not listed please contact the Connect Tech sales department for further information.
2-4 Chapter 2: Hardware Installation Status Port Address The Echo board provides a status port that indicates which ports, if any, are causing the interrupts. When read, the port will indicate a one (1) if the corresponding port has an interrupt request pending and a zero (0) if not. The least significant data bit (D0) represents the status of port 1. In multi-card installations the address for the status port on each card must be unique.
Chapter 2: Hardware Installation 2.5 Interrupt Selection You can configure Echo boards to use one, two or no interrupt request lines. To select the appropriate configuration, you must program DIP switch 8 on SW1 and the IRQ jumper block J1. When DIP switch 8 is on, all Echo communication ports will interrupt on the A channel. When switch 8 is off, the odd numbered Echo ports will interrupt on the A channel, while the even numbered Echo ports will interrupt on the B channel.
2-6 Chapter 2: Hardware Installation Many other devices such as the keyboard and disk drives also require an IRQ. Table 3 shows some typical IRQ assignments.
Chapter 2: Hardware Installation 2-7 Installing the Echo Adapter in your System To install your Echo adapter in your computer follow these steps: Computer components are very sensitive to static electricity. Make sure that you wear an anti-static wrist-band when installing adapters in your computer. Handle the adapter by its edges and place it on the anti-static bag or an anti-static mat. 1. 2. 3. 4. 5. Turn the power off to your computer.

Chapter 3: Software Installation 3-1 Introduction Echo boards are standard multi-port serial adapters that utilize ST16C554 UARTS. In many cases, users have software that will interface directly to the Echo boards. This section covers configurations for the following operating systems: DOS 3.XX - 6.XX Linux Multiuser DOS QNX 2.XX QNX 4.XX QNX 6.XX SCO Unix Solaris Windows 95 Windows NT Technical Tips: 1. Your Echo adapter may ship with diskettes that include README files.
3-2 Chapter 3: Software Installation - DOS DOS 3.XX - 6.XX Many DOS applications are designed to directly control the hardware of an 8250 style UART. For some applications, the DOS device driver provided with the Echo will help to integrate the extra communication ports quickly and easily into the system. Technical Tip 1. You can run under DOS the DOS programs porttest.exe and portfind.exe to verify your settings and assure you have no hardware conflicts.
Chapter 3: Software Installation - DOS 3-3 DFLEX.SYS DLEX.SYS is a device driver that allows you to set port addresses for software access of up to 32 ports . To install the device driver, add the following command to your CONFIG.SYS file: DEVICE = DFLEX.SYS [options] Where [options] are: P=hhh hhh specifies the I/O address of the ST16C554 N=d this parameter specifies an offset for the communication port numbers to start at.
3-4 Chapter 3: Software Installation - DOS Character Device Access Character device access provides a "high level" interface which is appropriate for simple applications and tests. Each port is given a device name which you can access similar to a file. The device name is formed by concatenating the port number to the name ( COM if not specified by the D= command ). For example, if two ports are installed with the parameter N=2, then the device names will be COM2 and COM3.
Chapter 3: Software Installation - DOS 3-5 Function 0 - Initialize the port Input: ah = 0 al = baud, parity, length dx = channel ( 0 = com1, 1 = com2, ...
3-6 Chapter 3: Software Installation - DOS Function 2 - Receive character Input: ah = 2 dx = port number Return: ah = port status ( timeout if bit 7 is set ) al = character received Function 3 - Return port status Input: ah = 3 dx = port number Return: ah = port status bit 7 = timeout bit 6 = trans shift reg empty bit 5 = trans hold reg empty bit 4 = break detected bit 3 = framing error bit 2 = parity error bit 1 = over run error bit 0 = data ready al = modem status bit 7 = data carrier detect bit 6 = r
Chapter 3: Software Installation - Linux 3-7 Linux Linux is a leading multi-user, multi-tasking operating system for Intel based personal computers. The Linux serial device driver provides an interface between the Linux kernel v.2.2.X or v.2.4.X and an Echo adapter. Technical Tip 1.
