| - | ====== Description ====== | ||
| - | With the available high power bridges, it was obvious to start doing something with it.\\ | ||
| - | This booster will put all previous boosters from GCA in the background.\\ | ||
| - | It is very small, only 70 x 60 x 50 mm, and can be used from 1 to Z scale.\\ | ||
| - | The base of this booster is an IBT-2 bridge unit.\\ | ||
| - | This unit has a maximum power option to 42 Amp, but this booster is designed not to handle more than 25 Amp.\\ | ||
| - | Short circuit shut off is handled on-board and maximum current is selectable by dip switch. (See below)\\ | ||
| - | On top of IBT-2 unit a board is situated that has all the necessary equipment for booster function.\\ | ||
| - | This board contains two small processors and various opto-couplers for isolated input and output.\\ | ||
| - | Booster also has so-called cut-out for use with Railcom\\ | ||
| - | Th ebooster starts automaticaly, | ||
| - | Processor IC1 is controlling the output pulses, and will switch off when pulses are incorrect or not available.\\ | ||
| - | Processor IC1 also handles the cut-out for Railcom.\\ | ||
| - | Processor IC5 handles the maximum selected current.\\ | ||
| - | When the output exceeds the selected value, booster is shut off, and will try to start again every second.\\ | ||
| - | Inputs for LocoNet Railsync, DCC232 (direct drive inside Rocrail) and CDE (lenz).\\ | ||
| - | Also any central station can be used to drive this booster.\\ | ||
| - | Power for this booster should be a DC output power supply, and the maximum Amp output of this power supply should be \\ | ||
| - | ALWAYS slightly more than the selected Amp on booster.\\ | ||
| - | The long run test proves that it is absolutely necessary to use a small fan for cooling , when the booster does more than 10 Amps.\\ | ||
| - | So a small fan was added, | ||
| - | But on the maximum load of 25 Amp, a larger fan is undoubtedly needed.\\ | ||
| - | Also, the position of the unit, where air can freely stream in upside direction through the cooling grid is essential.\\ | ||
| - | |||
| - | \\ | ||
| - | |||
| - | ====== Features ====== | ||
| - | * Useable for Railcom | ||
| - | * Easy selectable maximum output current. | ||
| - | * Input for Railsync (LocNet) | ||
| - | * Input for DCC232 (inside Rocrail, no central station needed. | ||
| - | * With extra adapter also useable for DCC232 via USB. | ||
| - | * Input for CDE (Lenz) | ||
| - | * Only extra cooling needed, if continuous output is more that 16 Amp.(Can be done by small 40x40 mm fan,) | ||
| - | * All signal inputs are isolated. | ||
| - | * Absolute maximum power input 24Vdc. | ||
| - | * also available without Railcom.(with additional firmware in IC1) | ||
| - | * also available for DDX with Motorola/ | ||
| - | * opto_isolated output for short_circuit indication. | ||

| - | ===== Mounting instructions ===== | ||
| - | The ORD-VC-12 board is mounted on top of IBT-2.\\ | ||
| - | The 1st edition of this board needed a small wire to +V of the IBT-2, for supply.\\ | ||
| - | In the presented edition, this is changed.\\ | ||
| - | The elco located besides the screw terminals on IBT-2, needs to be removed, to make place for 3-pins header (with middle pin removed).\\ | ||
| - | C1 on ORD-VC-1 board is connected to these pins, replacing the removed elco.\\ | ||
| - | On ORD-VC-1 board a 3-pin female header (middle pin removed.) is used two connect together.\\ | ||

| - | The kits will have mounting supports, which need to be used in the way as shown here {{: | ||

| - | ====== Selection of Volts for Power supply ====== | ||
| - | The choice of power supply depends of the used scale.\\ | ||
| - | |< >| | ||
| - | ^ Scale ^ Volt ^ | ||
| - | | N | 12..15 | ||
| - | | H0 | 15..19 | ||
| - | | 0 | 18..22 | ||
| - | | G | 18..24 | ||
| - | | 1 | 18..24 | ||
| - | |||
| - | \\ | ||
| - | \\ | ||
| - | | ||
| - | Since this unit can handle a large current , it is necessary to select the maximum current output.\\ | ||
| - | For example: If you use a power supply of 18V 4 Amp, the selection should be maximum 3 Amp on the booster.\\ | ||
| - | When power supply can not handle the maximum selected current, the booster will not be able to shut off when a short \\ | ||
| - | circuit occurrs.\\ | ||
| - | This can cause much damage to your materials, and maybe fire hazard.\\ | ||
| - | A special remark is to be stated for current versus wires, both between Booster and rails and also between booster and power supply.\\ | ||
| - | Do NEVER use wire that cannot handle the selected maximum current.\\ | ||

| - | ====== Using multiple boosters.====== | ||
| - | It might be a bit overdone, but if the need for multiple boosters is there, be sure not to mix different type of boosters with ORD-VC-1.\\ | ||
| - | **With any multi-booster combination on the same track, it is extremely advised to use only 100% equal boosters !** | ||

| - | ===== LED indicator. ===== | ||
| - | L1 just shows that 5 Volt power is available.\\ | ||
| - | L2 is On when booster is in normal function.\\ | ||
| - | L2 flashes fast (8 /sec) when short circuit is found (booster is off).\\ | ||
| - | L2 flashes slower (3/sec) when no pulses are coming in.\\ | ||
| - | \\ | ||
| - | ===== Signal input connections.===== | ||
| - | This booster needs a digital signal (DCC or Motorola) from any central unit.\\ | ||
| - | These can be connected in different ways.\\ | ||
| - | ==== LN1 (RJ12 connector) ==== | ||
| - | This connector is mainly used for LocoNet\\ | ||
| - | The signals in LocoNet (called Railsync) are connected to Pin 1 and 6.\]\ | ||
| - | ==== RS1 Serial connector (possible usb) ==== | ||
| - | Here a signal directly from Rocrail can be used\\ | ||
| - | In Rocrail this can be the internal command station DDX or DCC232.\\ | ||
| - | Used pin in the SUB-D9 connector are pin 3&5.\\ | ||
| - | ==== CDE1 connector ==== | ||
| - | Rail connections from any digital central unit can be connected to PIN C & D\\ | ||
| - | Here also a galvanic free output is available which will indicate a short circuit situation.\\ | ||
| - | These pins E and GND can be connected to any input port, for your own convenience.\\ | ||
| - | It is not much used, the booster controls its own short circuit protections, | ||
| - | but if you like it could be used to report back to the controlling pc program, that booster is off.\\ | ||
