Different models of Echo adapters may reside in a host
computer offering up to 32 ports per system.
ST16C554 UARTs control each port.
An addressable status control register to improve
performance.
Each port on an Echo has independent baud rate selection
offering baud rates from 50 – 115.2 Kpbs with 5, 6, 7 or 8
data bits and 1, 1.5, 2 stop bits, odd or even parity.
On board DIP switch allows the selection of ports 1 & 2 as
COM1 and COM2. It provides 8 predefined I/O address sets
and 8 predefined status port addresses.
Jumpers on the board give the user a choice of 8 IRQ lines to
run the board at. The on board DIP switch also provides the
choice of running the Echo on 1 or 2 or no hardware
interrupts.
System requirements are one ISA bus compatible slot; one
available IRQ line.

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.
Configuration
You must configure various settings and options before installing
your Echo adapter in your computer. In order to insure a
successful installation, please follow the steps in the order
specified below.
1.
Selection of I/O port addresses.
2. Selection of the status port address.
3. Selection of IRQs.
4. Installing the Echo adapter in your computer.
Your Echo adapter is very sensitive to static electricity. Make
sure you wear an anti-static wrist-band before you remove the
card from the anti-static shipping bag. When you remove the
board from the anti-static bag, handle it only by the edges and
place it on the anti-static bag or an anti-static mat.
Echo User's Manual, ver. 0.00
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. Please refer to Figure 2 for a description of
switch block SW1, while Tables 1and 2 provide the switch
settings for the various port address sets
However many other devices may require port addresses in your
computer's I/O address space. In most cases the factory setting is
sufficient, but when there is a conflict, SW1 may require a
different setting. Table 1 summarizes typical I/O port address
usage.
WARNING
Do not use a pencil to set the DIP switches as the lead graphite
may short-circuit the switch.

Echo User's Manual, ver. 0.00
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. DIP switch 7, combined with the selection
of the port addresses on DIP switches 3, 4 and 5, determines the
status port address. Tables 1 and 2 indicate the relationship.
Custom Status Port Addresses
Custom status port addresses are available with the Echo/ISA.
Please contact Connect Tech Customer Support for more details.
Echo User's Manual, ver. 0.00
Chapter 2: Hardware Installation 2.5
A
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.
IRQ jumper block J1 allows the assignment of IRQ lines to both
the A and B channels. If your application requires no interrupts
then you can remove both jumpers from jumper block J1. To
assign interrupts to either channel, go to the posts under the
selected IRQ line number and install the jumper(s) between the
centre post and the A post (A channel), and/or between the centre
post and the B post (B channel).
COM1 and COM2 normally use IRQ 4 and IRQ 3 respectively.
If you use the first two ports as COM1 and COM2, set switch 8
on SW1 to the off position and install a jumper between the
centre post and the A post on J1 under IRQ 4 (COM1). You
should install the other jumper between the centre post and the B
post on J1 under IRQ 3 (COM2). If you configure only one of
the two ports as a standard COM1 or COM2, then you can
relocate or remove the other jumper according to the
requirements of the controlling software. Please refer to Figure 3
for an explanation of IRQ jumper block J1.

Note: this example of shows J1 selected for IRQ 3 and 4 on
channels B and A respectively.
Echo User's Manual, ver. 0.00
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.
Table 3: Typical IRQ assignments

0 Timer output
1 Keyboard
2 Reserved
3 COM2, COM4, SDLC
4 COM1, COM3, SDLC
5 Unassigned (typically)

9 Reserved
10 Unassigned (typically)
11 Unassigned (typically)
12 Unassigned (typically)
13 Co-processor
14 Primary fixed disk controller
15 Secondary fixed disk controller
In most cases the default IRQ setting for your Echo adapter is
satisfactory. If an IRQ conflict exists between the Echo adapter
and another expansion device, you must choose another IRQ. To
select an IRQ simply install the jumper across the corresponding
pins for that IRQ on J1.

maximum of 32 serial ports. The standard COM driver and BIOS
will only support up to four ports. If your total number of
installed ports is four or less, use
COMSET to set the port address
to allow standard software access. To access more ports, you will
need to mount the
DFLEX.SYS device driver.
COMSET.EXE
As mentioned earlier,
COMSET allows you to set the port addresses
for standard software access (up to four ports). The syntax for
COMSET
is:
COMSET [[COM]n HHHH]
COMSET
COMSET COM2 2f8
COMSET COM3 0
will display up to four non-zero com
address settings
will set COM2 to 2f8 (hex)
will set COM3 off

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
file:
DEVICE = DFLEX.SYS [options]
Where
[options] are:
specifies the I/O address of the ST16C554
P=hhh
N=d
D=name
hhh
UART.
this parameter specifies an offset for the
communication port numbers to start at.
this parameter changes the name of the ports to
something other than COM.
CONFIG.SYS
Note: You must specify at least one option
Example 1:
( com1 .. com8 )
DEVICE=DFLEX.SYS P=3f8 P=2f8 P=210 P=218 P=220 P=228 P=230 P=238
Example 2:
( com3 .. com10 )
DEVICE= DFLEX.SYS P=200 P=208 P=210 P=218 P=220 P=228 P=230

CTIMODE
The
CTIMODE command allows you to configure the extra serial
ports. It is used with the
CTIMODE COMn:baud,parity,databits,stopbits
COM name:
Accessing Ports
You can access the ST16C554 UARTS from DOS through the
driver
DLFEX.SYS. We provide two methods of access; character
device access and software interrupt 14h access.
Echo User's Manual, ver. 0.00
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
names will be COM2 and COM3.
Some programming languages will assume that access to COMn is
limited to the number of communication ports supported by the
computers BIOS. To avoid this problem, the name can be
changed. If two ports are installed with the parameters
the names will be
SERIAL1 and SERIAL2. In this case, the N=
parameter is not added to the number of the name.
INT 14h Access
The DFlex DOS driver provides the standard four INT 14h
functions for the additional ports supported. To interface to these
functions, DX is set to the port number minus 1. If the
parameter has been specified, this value must be added into the
DX to skip the standard ports.
N=2, then the device

Chapter 3: Software Installation - QNX 2.XX 3-11
QNX 2.XX
When installing Echo boards under the QNX 2.XX operating
system, it is important to note the following:
Note:
1. After booting, QNX looks for serial ports at the following
addresses: 3F8, 2F8, 280, 288, 290, 2A0, 2A8, 2B0, 2B8,
3E8, 2E8 hex.
2. If QNX finds ports at these addresses, QNX assigns the
names $tty3 ($mdm), $tty4 ($term1), etc.
Technical Tip: You can use
osconfig to alter or add to these
addresses.
Configuration
Many computers include both COM1 and COM2 directly on the
motherboard. With this in mind, check your computer to see if it
has either or both of these ports as standard equipment or as
options. To avoid possible conficts with COM1 and COM2,
Figure 6 describes a recommended DIP switch setting for port
addresses. See Figures 1, 2, and 3 in Chapter 1: Introduction
for the location of switch block SW1.
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. You will find these programs on the
DFlex DOS Driver diskette (p/n: DISK306)

In choosing an interrupt request line, you should note that QNX
vectors interrupt 3 and 4 to the serial handler. However, QNX
enables interrupt 4 only. If you are using interrupt 3, you will
have to use the following command to enable interrupt 3:
Example
stty inton=3
If you use an interrupt other than 3 or 4 you will need to use the
following commands:
Example
stty intcp=4,nn
stty inton=nn
where nn is the interrupt number to be used
Note:
Due to limitations in QNX 2.XX, only interrupts less than or
equal to IRQ 7 will work with standard serial port boards.
Echo User's Manual, ver. 0.00
Chapter 3: Software Installation - QNX 2.XX 3-13
Use the stty intcp command to vector the selected interrupt to the
serial handler and the stty inton command to enable that interrupt.
Note: You can find more information on these commands by
referring to the stty command in your QNX Operating System
Manual.

You now must make an entry for the Echo adapter in the file
space.c. This entry tells the operating system about the Echo
adapter:
1. Change to
space.c.
2. Open the file
/etc/conf/pack.d/sio directory and backup the file
space.c with your editor. You will find listings
for many different serial adapters so search the list until you
find an entry for a Stargate adapter. The Stargate entries are
essentially compatible with the Echo adapter. This entry
should look like the following:
{2,STARGATE,8,4,8,(sd)0x280,0x280+STAR_POLL,8,
MCRBIT3},/*AT-Stargate*/
We can describe the parameters for this entry as follows:

Where:
[COM]
This parameter allows you to assign a
COM to the serial adapter. There are
four available COM assignments
under SCO Unix.:
0 = COM1 1 = COM2
2 = COM3 3 = COM4
Note:
COM refers to a serial board and
not a specific port. There is no
relation between COM1, COM2

file and make the following choices:
- Enter the default baud rate, i.e. 9600
- Enter m for 9600,n,8,1.
The system will now prompt you with a number of yes or no
questions about rebuilding the kernel. Answer yes to all of these
to build the kernel with the new Echo settings. This will take
about two minutes to complete.
Step 5
With the Echo installed you can reboot the system by typing:
sync;sync;reboot
If you still need to install the hardware you can shutdown the
system by typing:
sync;sync;shutdown
or
sync;sync;haltsys
You should see the additional Echo ports in the list of
installed/found devices displayed at bootup. If you miss this
message, you can find it in the file
/usr/adm/messages by typing

Other Configurations
It is possible to run your Echo board using I/O addresses and
interrupts other than those listed above. In order to do this, it will
be necessary to modify certain system files. Consult the "Release
Notes" section of your operating system manuals or contact
Connect Tech's Customer Support for more information.
Technical Tips
If you experience difficulties installing your Echo adapter try the
following steps:
1. Check to see if you have followed the above procedures
closely.
2. Check for conflicting devices in your system. It is possible
that there is a conflict between the Echo adapter and
another board in the system. This could be an IRQ or I/O
port conflict. Try using the porttest.exe and portfind.exe
found on the DFlex DOS Driver diskette (p/n: DISK306) to
find the hardware conflicts.
3. If you use a system with a Plug and Play(PnP) BIOS or PCI
bus, you might have to configure the CMOS setup for nonPnP devices like the Echo adapter.
4. If you need to remove/un-install the Echo, you should use
the mkdev serial utility and follow the options for (r) remove
a board. If you decide that the Echo adapter is not working
due to a conflict, you should remove the board with mkdev
serial, reboot and then run mkdev serial to install the Echo at
some alternate settings.

Technical Tip:
Please ensure that you terminate the DCD or CTS signals if your
application does not use them. The common way to do this is to
connect DCD to DTR and/or to connect CTS to RTS. Failure to
do so may result in a loss of a performance on your Echo
adapter.

Connector Box /Pinouts
You may order the Echo with an external I/O Box option. The
I/O Box option comes with a metal bracket that can be mounted
on a wall or other surface. When you receive the I/O Box, this
bracket is clipped on to the back of the connector box. If you
wish to attach the I/O Box to a wall or other surface, just remove
the bracket, fasten it in place, and then re-attach the connector
box. If you wish to set the I/O Box on its rubber feet only, just
remove the bracket from the back. See Figure 18 for the
orientation of the I/O Box and Table 7 for the DB9 pinouts on
the connector box.
