Step 2: Configure the DaughterBoard

There are two configuration options that must be set

on the daughterboard; the interface port and the CSU/

DSU powerup configuration.

SYNC/570i-56 daughterboard

Configure the Interface Port

The selectable interface port is hardware-configurable

using two jumper sets on the daughterboard.

Note: When disconnecting the daughterboard use

adequate precautions (such as a grounding

wrist strap that is connected to earth ground)

to prevent electrostatic damage.

a. From the host side, remove the metal screws

which secure the daughterboard to the mother-

board.

b. Separate the daughterboard from the mother-

board.

Note: There is one connector holding the daugh-

terboard. Do not pull with a twisting

motion.

c. Install the jumpers for the correct interface.

When the jumpers are on the top two rows, the

interface port is set to V.35. When the jumpers

are on the bottom two rows, the interface port

is set to EIA-232.

d. Reconnect the daughterboard to the mother-

board by matching the connectors and screw

wells. Push the daughterboard onto the moth-

erboard and replace the screws.

CSU/DSU Powerup Configuration

The DIP switch that configures the initial powerup

configuration of the CSU/DSU can be changed with

the daughterboard connected to the motherboard.

The initial powerup configuration of the CSU/DSU is

determined by the DIP switch settings. This configu-

ration can be overwritten by AT commands.

This switch can be changed without separating the

daughterboard from the motherboard. With the boards

connected, the OFF label on the switch block is not

visible. OFF is away from the base of the daughter-

board, toward the motherboard.

Step 3. Install the adapter in the Computer

Before you Begin

• Record the serial number of the adapter (located

under the part number label). This will enable Digi

to provide you with better service, should the need

arise.

• Shutdown and unplug power from the computer.

• Put a ground strap on to ground yourself. If one is

not available, ground yourself by touching an

unpainted metal surface, such as the computer’s

chassis.

Installation Procedure

1. Remove the computer cover.

2. Locate an available 16-bit slot in your computer

and remove the slot plate.

3. Remove the hold-down screw at the top of the

slot. Remove the slot bracket.

4. Insert the adapter into the slot and screw the end-

plate to the computer chassis. The endplate must

be screwed into the computer chassis to remain in

compliance with Part 15 of FCC rules.

5. Replace the computer cover.

6. Reboot the computer. The LED indicator will dis-

play a steady red light indicating there are no

lines connected.

Step 5. Verify the Installation

The User Diagnostics diskette and the loopback con-

nector are designed to verify correct installation of the

SYNC/570i-56 adapter. When running the diagnostic

program, make sure no devices are connected to the

adapter ports.

1. Boot the system from a DOS-bootable diskette or

partition. The

prompt should display on your

screen.

2. Insert the User Diagnostics diskette.

3. Install the Telco (RJ-45) and EIA-232 loopback

connectors on the adapter.

4. Type

A:\SYNC570

to start the diagnostic pro-

gram.

5. Follow the instructions on the screen.

The diagnostic program displays the current the IRQ,

base memory address, and the base I/O address. You

may modify the address and IRQ selections from the

diagnostic program to test the adapter. The IRQ must

be active and you must select a non-zero address.

Note: For ISA adapters, the following I/O

addresses are not allowed when running

the user diagnostic program; 0x000

through 0x100, 0x1F0, 0x230, 0x240,

0x250, 0x260, 0x270, 0x2e0, 0x2F0,

0x330, and 0x360 through 0x3FF.

The diagnostic tests will fail if there is a memory

address (base I/O address or 16KB memory window)

or interrupt conflict. If the diagnostic program cannot

determine your switch settings, there may be a con-

flict as well. Try changing the memory addresses and

IRQ if the diagnostic program fails.

Other Settings

IRQ and Memory

The memory address and interrupt line (IRQ) are soft-

ware-configurable via either your operating system or

an installable driver. The memory address consists of

a 16KB window.

Fast Select

Jumper JP1 on the ISA SYNC/570i-56 adapter con-

trols the Fast Select circuitry on board. The adapter is

shipped with a jumper connecting pin 2 and pin 3 of

JP1. This option allows the adapter to function with

any combination of 8, 16, or 32 bit video and/or net-

work cards supporting Fast Select.When pins 1 and 2

are jumpered, the adapter must be installed in a

128KB paragraph which contains only 16 or 32 bit

cards. The default setting (pins 2 and 3 jumpered)

works in most computers and should not be changed

without verification from Digi Technical Support.

What Next?

Install and configure the driver for your SYNC/

570i-56 adapter. Consult the DataFire Access

Resource CD for driver installation and configura-

tion procedures. The DataFire Access Resource CD

also contains cabling information, diagnostic and

troubleshooting information, and product features

and specifications.
