Selecting the Base I/O Space Address Location

The

host addresses I/O devices on the card by using their I/O space address. The

host addresses individual devices through registers that have addresses based on

the I/O space base address. The registers are 2 bytes long.

The card comes set to base I/O space address 220. Y

ou may find that this

selected address has been allocated to other interface cards or expansion memory

cards you have installed in your computer system. If this occurs, change the

switch settings to an open address.

Important: When selecting configuration settings, check for conflicts with

other interface cards and system memory. If there is a conflict, the

system will not operate properly.

o select a new base I/O space address:

1. Pick an available address from the I/O map area of the host computer’s

memory

. Be sure to choose a block that is 2 bytes long.

Important: Each card requires 2 bytes of I/O space.

Use W

orksheet D to select a new base I/O space address for the card

(i.e., to determine the switch settings for the new address).

Follow this guide to properly set your switches:

Interpreting the Status Indicators on the KTCX15

The status indicators on the card give you information about the card and the

network when you’re connected via the BNC connectors. T

able B outlines the

states and explains what each state means to you and the action you should take,

if any, to correct that state.

status interpretation

• steady – indicator

is on continuously in the defined state.

• alternating – the

two indicators alternate between the two defined states at the same time (applies to

both indicators

viewed together

). The two indicators are always in opposite states, out of phase.

• flashing – the

indicator alternates between the two defined states (applies to each indicator

viewed

independent

of the other). If both indicators are flashing, they must flash together

, in phase.

configuration keeper node is the node responsible for distributing ControlNet configuration data to all nodes on the

network.

Important: When

you have a cable connected to the network access port

(NAP), the LEDs are meaningless.
