In the Offline position, this switch logically

disconnects the DCM from the network (just as

if you pulled the cable from the connector.)

Once this switch is moved to the Offline

position, the DCM will not communicate with

the network.

If you move the switch to the Online position,

the DCM will communicate with the network,

but not until the master sends another request

for communication. This does not operate like

the reset switch on many personal computers.

The DCM station address is set by the two

rotary switches located on the front of the unit.

Addresses are in hexadecimal format with

valid addresses from 0 (only used for the

master station) to hexadecimal 5A. The

addresses do not have to be sequential, but

each station must have a unique address.

The top rotary switch is used to set the most

significant digit of the HEX address. The

bottom switch is used to set the least

significant digit the HEX address. For

example, to set a DCM address of HEX 10

(decimal 16), set the top rotary switch to 1 and

the bottom rotary switch to 0.

NOTE: The DCM address switch settings are

only read at power up. If you’ve want to

change the address and the DCM is already

running, you’ll have to cycle the system power

for the base containing the DCM to initialize

the change.

Even though the DCM address is set in hexadecimal, it’s a good idea to remember

the decimal equivalent. This is because the communications program and the

DirectSOFT package use the decimal equivalent of the HEX address. It’s easy to

convert from HEX to decimal.
