This device complies with Part 15 of the FCC Rules provided the enclosed instructions are followed to the letter. Use of the device is subject to the following conditions: (1) this device must not cause harmful interference and (2) the operation of this device should not be influenced by unwanted interference. More information about FCC can be look at http://www.fcc.gov This relay card can be used in several ways: Stand alone card, addressed by switches or open collector outputs.
Features & specifications Features : Eight high quality relay contacts, 5A/230VAC max. Relay outputs are transient suppressed using VDR’s. LED confirmation on each relay contact. Eight drive inputs to use with open collectors or regular switches. RS232 input to drive the card with computer or terminal. High or low impendant selection (10K or 1K). Optional RF driving possibility using RX433 type module(*). Together with K8058 eight channel RF remote control.
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.
Assembly hints ⇒ 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.

Control options 19. Control options 1) RS232 cable : TxD 3 GND 5 53 5 3 9 pole 3 : TxD 5 : GND 25 pole 2 : TxD 7 : GND 0 IN TO PC SUBD 9 pole female TO K8056 10 meter max. Do not use a null-modem cable !! Jumper setting : Place JP1 in ON position Fig 1.0 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.
Addressing 20. Addressing the K8056 card through RS232 commands. 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.
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) 4.

Diagnostic / Test software 21. DIAGNOSTIC / TEST SOFTWARE 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 X 2. Eight toggle buttons Y 3. Eight momentary buttons Z 4. One button is reserved as 'emergency' function [ Momentary : Hold the key to activate the output and release the key to deactivate it.
