Assembly hints

1. Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 Make sure you have the right tools: • A good quality soldering iron (25-40W) with a

small tip. • Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to

the tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and enables you to make good connections. When solder rolls off the tip, it needs cleaning.

• Thin raisin-core solder. Do not use any flux or grease. • A diagonal cutter to trim excess wires. To avoid injury when cutting

excess leads, hold the lead so they cannot fly towards the eyes. • Needle nose pliers, for bending leads, or to hold compo-

nents in place. • Small blade and Phillips screwdrivers. A basic range

is fine.

For some projects, a basic multi-meter is required, or might

be handy 1.2 Assembly Hints : ⇒ Make sure the skill level matches your experience, to avoid disappointments. ⇒ Follow the instructions carefully. Read and understand the entire step before

you perform each operation. ⇒ Perform the assembly in the correct order as stated in this manual ⇒ Position all parts on the PCB (Printed Circuit Board) as shown on the draw-

ings. ⇒ Values on the circuit diagram are subject to changes. ⇒ Values in this assembly guide are correct*

⇒ Use the check-boxes to mark your progress. ⇒ Please read the included information on safety and customer service * Typographical inaccuracies excluded. Always look for possible last minute manual updates, indicated as ‘NOTE’ on a separate leaflet. 1.3 Soldering Hints :

1- Mount the component against the PCB sur-face and carefully solder the leads

2- Make sure the solder joints are cone-shaped and shiny

3- Trim excess leads as close as possible to the solder joint

REMOVE THEM FROM THE TAPE ONE AT A TIME !

1) RS232 cable :

Do not use a null-modem cable !! Jumper setting : Place JP1 in ON position Place JP2 in RS232 mode, see fig 1.0. Choose the impedance, high or low with JP3. Define the impedance on experimental use. The impedance depends on the length of RS232 cable you’re using.

Normally the impedance is 10Kohm => select normal. If you use current loop (long cable), select current. The impedance will be 1Kohm.

2) Wireless link :

It is possible to use the K8056 together with a remote control (e.g. our K8058). In this case an optional receiver module type RX433 is available.

The receiver module is mounted on the left hand side of the K8056 board. Watch the position, the coil point to the relays of the K8056. If you choose wire-less operation, make sure to set jumper JP1 & JP2 in right position.

Transmission quality depends on your environment. Other RF sources might interfere with your signal.

Jumper setting : Place JP2 in RF mode. Place now JP1 in ON position (see fig. 2.0)

Put JP1 in OFF mode if you don't use a remote control (RS232 or wireless link)

Note: A Test program can be downloaded from our web site. The source code (VB) is also available. (English only)

1) Instructions for software design :

As the instructions consist of a string of ASCII characters, it is easy to design software which transmits the instructions via the serial port of the PC.

Port settings are: 2400/8/N/1

For wired operation, the instruction sequence needs to be sent at least twice.

For wireless operation, we recommend to send the instruction string at least 5 times in a row to ensure proper reception under all conditions. For improved reliability, add a pause of a least 300ms between two different instructions.

Please note that environmental conditions can interfere with the signal. Therefore, the unit is not suited for use as or as part of any kind of equipment which might cause harm to people or property if a malfunction should occur.

2) Instruction sequence :

To execute a command, the correct sequence needs to be sent to the K8056. Basically, a command sequence looks like this : 1. CHR$(13) 2. card address (1..255) 3. instruction 4. address (1..255) or relay# ('1'..'9' ASCII) 5. checksum (2-complement of the sum of the 4 previous bytes + 1) 3) Instructions : 'E' : Emergency stop all cards, regardless of address. Carefull, relays turned

on by open collector inputs will not be turned off by this command).

'D' : Display address. All cards show their current address in a binary fashion. (LD1 : MSB , LD8 : LSB)

'S' : Set a relay. 'S'-instruction should be followed by relay # '1' to '8'. ('9' sets all relays at once).

'C' : Clear a relay. 'C'-instruction should be followed by a relay # '1' to '8'. ('9' clears all relays at once.)

'T' : Toggle a relay. 'T'-instruction should be followed by a relay # '1' to '8'.

20. Addressing the K8056 card through RS232 commands.

Addressing

11

Addressing

'A' : Change the current address of a card. 'A'-instruction should be followed by the new address (1..255)

'F' : Force all cards to address 1 (default) 'B' : Send a byte. Allows to control the status of all relays in one instruction, by

sending a byte containing the relay status for each relay. (MSB : relay1, LSB : relay8)

Note : You can download software from our website www.velleman.be which makes it very easy to control your relay card(s). A. Operating modes: The K8056 features 4 operating modes : 1. Set all outputs active / non-active 2. Eight toggle buttons 3. Eight momentary buttons 4. One button is reserved as 'emergency' function Momentary : Hold the key to activate the output and release the key to deactivate it. Toggle : Operates according to the principal of a classic switch, i.e. press a key once to activate and press again to deactivate. Emergency function : Deactivate all the outputs on the same time. B. Address selection: 1. Select the address of the relay card you want to control. 2. Confirm the selection by clicking the "show addr." button.

NOTE : Make sure that you have selected the correct serial port! C. Changing address : Choose the address you want to allocate to the relay card and confirm it by clicking the "Chang addr." button.
