TV REMOTE HO SWITCH CONTROLLER

There would be a high controller

and a low controller. Select the

high or low controller using the

Channel + or Channel –buttons

respectively.

The TV Remote HO Switch

Controller (TVHOSC) system uses

a universal TV remote to control

10 HO turnouts or switches. The

universal TV remote is pictured

below. Press one button to close

the switch and a second button to

open the switch. It is that easy!

The unit is fairly compact and is

pictured to the right. It is mounted

on a small block of wood and will

easily mount on a train layout. A

quarter coin is also shown.

If you want to control more than

10 switches, two controllers can

used together. That is use one

remote to control the two

controllers.

USING THE REMOTE

The remote is a universal type which has

to be configured for a Sony TV. This

means the remote transmits the codes

that a Sony TV would use.

Instructions are included with the remote

to program it for a Sony TV.

To use the remote point it towards the

TVHOSC unit. There is an IR receiver

mounted on the unit. If you examine the

remote you will notice that there are ten

number buttons 0 to 9. Theses ten

buttons are used to first select a switch.

Press a number button to select a switch

first. Then using the Volume buttons.

Press Vol + to open the switch and Vol –

to close the switch.

The Chan + and Chan – are used to

switch the controller between two

systems

Make sure

the remote’s TV button is pressed too.

The included remote is a universal type which has to be configured for a Sony

TV. You can in fact use any universal remote programmed for a Sony TV. You

must also have the TV button pressed to tell the remote to use TV codes. Most

universal remotes can control several devices such as a TV, VCR, and DVD.

You want to set the remote for a TV.

To use the remote point it towards the TVHOSC unit. There is an IR receiver

mounted in the center, on one end, on the unit (See below). You will soon

discover that the remote signals will bounce off the ceiling and walls and will

easily find their target (the TVHOSC unit).

SETTING the TIME DELAY

A variable resistor control is located on the main circuit board. This blue control

sets the time delay or the amount of time that power gets applied to a switch.

If power is applied to aswitch for too long then the switch gets hot and may even

eventually start to melt. If power isn’t applied long enough the switch will not

operate correctly. You want to find the mid-point.

RECEIVER

You want to apply power to a switch for just long enough so the switch switches.

Once this blue control has been set, the unit will keep using this setting in

applying power to all switches connected to the unit.

The unit comes with the blue dial of the pot, set in its center position. The term

potis short for potentiometer. It is a variable resistor. Looking at the picture

above, turning the blue dial clockwise decreases the time and counterclockwise

increases the time.

You will discover that there is a screwdriver slot in the center of the control. A

small 1/8 inch flat blade screwdriver is best to use when adjusting this blue dial.

Care must be taken not to turn the blue control too far. It will notturn or rotate

continuously. The unit is shipped with the control in it mid position.

Whenever you make an adjustment to the blue control you must also press the

reset button to cause this new setting to be read by the unit. Adjusting the pot is

largely trial and error. Rotate the pot slightly, press reset and try to control a

switch. When you have found a setting where the switch operates correctly, you

are done.

WIRING THE TVHOSC UNIT

The unit can control 10 switches. Looking at the unit there are two rows of 10

terminals making 20 screw terminals total. If you examine a switch you will see

3screws. There is a center common terminal with the other two screws being

attached to the two switch coils. Here is a wiring diagram:

This table shows the connections:

SWITCHES

The lengths of wire used to connect the switches should be kept as short as

possible. Use at least 22 gauge wire. The local train club has such a large

layout that they use 14 gauge wire to connect their switches. As the wire gauge

number gets smaller, the wire gets larger.

Current, Current, Current….

Switches (or turn-outs as they are called) consume an enormous amount of

current. A typical Atlas switch consumes 2 amps of current when switching. At a

local train club where they use switch machines,the current was measured and

found to be 3 amps!

With this much current flowing it is no wonder why these switches get hot if the

power is applied too long.

EXPANSION

If you want to control more than 10 switches, two controllers can used together.

That is use one remote to control the two controller boards.

There would be a high controller and a low controller. Select the high controller

using the Channel + button and low controller using the Channel -button.
