1 OPENCOCKPITS IOCard USBRELAYS INSTALLATION AND USER S MANUAL

2 INTRODUCTION The USBRelays card is designed to manage up to 7 power relays. We also have in it 5 analogic inputs, to connect up to 5 potentiometers. The connection to the PC is through the USB port and when is connected will auto install as HID device and is controlled by the IOCP protocol. As interesting option, the card can be connected directly to the Master card and run through the outputs of this card. There is also a variant with the option to connect directly to the Master card and not through the USB port, that is disconnected in this version. COMPONENTS LIST - C1 = CAPACITOR 220nf - C2, C3 = CAPACITORS 22Pf - C4, C5 = CAPACITORS 0.1Mf - D1 D8 = LED DIODES - IC1 = MICROCHIP 16C745 - IC2 = INTEGRATED CIRCUIT ULN2003A - J0 = CONNECTOR +5V - J1 = CONNECTOR USB - J2 = JUMPER TO SELECT EXTERNAL/INTERNAL POWER SOURCE - J3, J4, J5, J6, J7 = CONNECTORS 3 PINS - P2 = CONNECTOR DB9 - Q1 = QUARTZ CRYSTAL 6MHZ - REL1 REL7 = RELAYS OMRON G5LE 1 - R1 = RESISTOR 1K5 - R2 = RESISTOR 10K - R3 = RESISTOR 100R - R4 = NOT USED (FUTURE OPTIONS) - R5 R12 = RESISTORS 470R - T1, T2, T3, T4 = SCREW CONNECTORS INSTALLATION AND USER S MANUAL 2

3 PRINCIPAL MEASURES: CONNECTORS DESCRIPTION: J0 = Power connector +5V. J1 = Allows to connect to the PC directly though the USB port. At this moment the PC recognizes the card and automatically install the driver for HID devices. J2 = This jumper allows us to select the power source, if the jumper is closed the feed goes from internal source, and i fis open goes from an external source. J3 a J7 = Analogic inputs connectors. P2 = Type DB9 connector, to connect the card thorugh the Master outputs directly, without use the USB port (never will be connected the two port at the same time) WIRING DIAGRAM The wiring is very simple, having each relay 3 correlative outputs on the fast screw connectors T1 to T4, corresponding in this order to the common pin (1), normally closed (2) and normally open (3). When the relay is deactivated the circuit from pin 2 is always closed, and the 3 is open, so, when the relay is activated, then the circuit 2 is open and the 3 is closed. INSTALLATION AND USER S MANUAL 3

4 Use example: We want to turn on the maps lamp, that is a 220V lamp and also want that automatically turns off the ambient light lamp that also is a 220V lamp, which is ALWAYS on, then we can use the card USBRelays, we must connect a side of the ambient light lamp to the pin COM and the other side to the pin2 (NC normally closed) and in other way a side of the map lamp to the COM pin, and the other side to the pin3 (NO normally open), without forgetting to feed the lamp from the electric net (see picture below) and, by connecting the card the ambient light goes on automatically and the maps light will remain off, but when we active the relay, the ambient lamp turns off and the maps turn on, also, when we deactive the relay the effect is opposite. INSTALLATION AND USER S MANUAL 4

5 USING SIOC Make sure you have installed version 3.46 or higher, if not you can download the latest version here: Once you have the correct version, the first thing to do is set the parameters on the sioc.ini file to make sure that the card is correctly identified with the Device number as corresponds. We will edit the entry in the sioc.ini file, so we assign an index of device to each card that we will install, create an entry in the file per connected card, and would be in following format: USBRelays=XX,YY Where XX indicates the index number, within our system and YY is the number of device from the USB port where is connected. For example, if we connect two USBRelays cards with the device numbers 35 and 42 (these numbers can be easily find in the SIOC.exe program itself, since it will provide us information on the card) then would declare the sioc.ini as folows: USBRelays=1,35 USBRelays=2,42 Isn t a problem to have more IOCards connected in this computer, while they are correctly defined, nor to have Opencockpits modules also connected. RELAYS: To refer to the number of relay accurately, we must consider the index number we have assigned to each card USBRelays. Now in SIOC, we must define the output in standard form: Var VVVV, name NNNNNNNNNNNNNN, Link USB_RELAYS, device DD, Output S VVVV= offset number NNNNNNNNNNNNNN = offest name (optional) DD = Index number as defined in ini (optional, if we have defined the card as number 0 no matter refer to the number of device) S = relay number 1 7 Definition example: Var 0001, name rele_maps, Link USB_RELAYS, Device 1, Output 5 ANALOGIC INPUTS: To read the analogic inputs we should use the following format: Var VVVV, name NNNNNNNNNNNN, Link USB_ANALOGIC, Device DD, Input# EE, posl LLL, posc CCC, posr RRR INSTALLATION AND USER S MANUAL 5

6 EE = analogic input number 1 5 LLL = maximum position to the left. CCC = center position of device RRR = maximum position to the right. The rest of parameters will use as on relays definition. Analogic definition example: Var 1506, name pot_flaps, Link USB_ANALOGIC, Device 1, Input# 2, posl 1, posc 128, posr 255 EJEMPLO SCRIPT DE SIOC Connect to the USBRelays two lamps on the number 4 relay, as we can see on the above image, we also have connected to the Master card input a toggle switch. Run SIOC (in this case doesn t need the FS running, because the lighting of these lamps have no real interaction with the simulator, and mostly in all purposes of this card) with the script loaded we can see that the ambient light is on and the map one is off, if we toggle the switch to the ON position, then the map lamp will turn on and the ambient one will turn off. Var 0001, name rele, Link USB_RELAYS, Device 1, Output 4 Var 0002, name map_switch, Link IOCARD_SW, Input 11 { IF &map_switch = 1 { &rele = 1 } ELSE { &rele = 0 } } Note: Software programs, circuits and content published in this paper and on our website are copyrighted by their developers, who doesn't consent to their use for commercial gain, unless authorized in writing.
