Connecting Your MO-690 Digital Master Controller
The MO-690 Digital Master Controller comes ready to be connected
to your Märklin 6050 or 6051 Digital Interface. It is necessary
to install the 9 volt battery provided into the back of the transmitter.
Two other electrical connections must also be made.
First, plug the 6-pin plug into the receptacle on the Märklin
6050/51 Digital Interface on the right side. The cable supplied
should be long enough to allow you to conveniently position the
receiver where its indications can be seen by you most of the
time. It is not necessary to have the infra-red receiver in view
when transmitting signals as the infra-red signal will "bounce"
off most lightly colored walls. This allows you to stand behind
the receiver while bouncing commands off the walls on the far
side of the room. The MO-690 Digital Master Controller has demonstrated
reliable control at distances exceeding 40 feet.
The second connection is the power supply for the receiver. This
is the small transformer included which supplies 9 volts AC. This
transformer's output plugs into the rear panel of the receiver.
When power is applied to the receiver for the first time each
day, all LED's will illuminate along with indications of "8"
in each of the indicator windows as an internal testing measure.
After a short time delay, the unit extinguishes all indications
while waiting for your "power ON" command.
To allow proper operation the dip switches on the 6050/6051 must
be set with 1, 2, 3 ON. When using the 6050 Computer Interface,
the white CTS lead must be disconnected at either end of the furnished
cable. This is due to a bug which existed in the original 6050's.
Locomotive Operation
Upon initial system startup, locomotive "01" appears
in the receiver window. Locomotives are selected by depressing
the "L" button on the transmitter. Next, the locomotive
number (e.g."05") is selected using the numbered keypad
on the transmitter. Speed for all locomotives is initially zero
and functions initialize as OFF. As long as locomotive codes selected
fall within the range of 0-80, the transmitter will agree with
the code selected. When a number outside this range is selected,
an indication of "00" is displayed. At any time, after
"L" is depressed, the next 2 digits selected will be
accepted and displayed (0-80). Once the desired locomotive has
been selected, you are then able to modify the pre-existing function
status, speed and/or direction of travel.
Depressing the "FN" key toggles the locomotive function
between "ON" and "OFF".
Depressing the up or down arrow keys will increase and decrease
the locomotive speed in steps of 1 (one) in a speed range of 0-14.
Depressing the double ended arrow requests a speed of zero and
then reverses the locomotive. This is indicated by the direction
indication changing from ] to [ and an indicated speed of "0".
This is useful when making an "emergency stop" of ONLY
the selected locomotive.
Anytime a previously controlled locomotive is re-selected, the
receiver will indicate the last requested speed, direction and
function status. This results in a "bumpless" re-selection
of the locomotive.
