Installation

To prepare your card for installation the following user-settable hardware option should be checked:

Item

Switch S1

How to set

S1-1 8 (hex)

S1-2 10 (hex)

S1-3 20 (hex)

S1-4 40 (hex)

S1-5 80 (hex)

S1-6 100 (hex)

S1-7 200 (hex)

S1-8 400 (hex)

300 (hex) is the

default base

Description

Switch S1 sets the card address on the PC/104 bus. The selected card address

is the additive value of the switch settings indicated to the left. Moving the

switch to the ‘off ’ position adds that value to the final base address. For

example, to select a base address of 340 (hex), the following switch settings

would be selected:

S1-1

on

S1-2

on

S1-3

on

S1-4 off

S1-5

on

S1-6 off

S1-7 off

S1-8

on

The card address selected using S1 must match the address expected by your

software. In addition, this address must not be used by other cards. From the

base address selected, 8 addresses are used by the Navigator-PC/104 card. For

example, if 300 (hex) is selected, then locations 300 - 307 will be used by the

card, and cannot be used by other cards on the bus.

If you are using differential connections leave these resistor packs installed. See

section 2.4.2, QuadA, QuadB, Index, page 32, for more information on encoder

inputs.

If you are using single-ended encoder connections, remove the resistor packs.

See section 2.4.2, QuadA, QuadB, Index, page 32, for more information on

encoder inputs.

1.7 Connection Summary

for Navigator-PC/104 Cards

The following sections summarize the connections you should make for various motor types.

Generally, the motor type you will install is specified by the card type purchased. See table, page 7.

However with the mixed-motor cards (part number MB802820, MB802840) both brushless DC, DC

brush and microstepping motors can be connected to the same card.
