1. Each bit within the byte indicates whether the corresponding relay is operated or not If the bit is 1 then the relay is operated if the bit is 0 then the relay is released Eg R55 relays 1 3 5 7 ON all others OFF ROF relays 1 4 ON all others OFF Sx relay STATUS where x relay number A 0 zero is returned if the relay is released 1 if operated The command S0 returns the status of ALL relays In this case a hex byte is returned Each bit within the byte indicates the status of the corresponding relay Eg S3 returns the status of relay 3 SO returns the status of ALL relays Ix INPUT status where x input number A 1 is returned if the input is enabled 0 otherwise The command 10 returns the status of ALL inputs As with the S command a hex byte is returned Bits 0 3 indicate the status of inputs 1 4 Bits 4 7 are unused and are set to 0 Eg IL returns the status of input 1 I0 returns the status of ALL inputs A special command will print the software date Audon Electronics 123 High Road Chilwell Nottingham NG9 4AT UK Phone 44 0 115 925 8412 Fax 44 0 115 925 9757 email info audon co uk Page 42.

3. SPO RL8 BOT DaR Sa Port Relay ELECTRONICS and Opto Input boar The SPO RL8 provides 8 relay and 4 optically isolated inputs for control and sensing applications It is controlled via a serial port using a set of simple text commands Connection to the real world is via pluggable type screw terminal blocks Power can be supplied via a 9 12V DC power supply such as a wall adaptor rated at 5 00mA minimum The SPO RL8 comes with a simple Windows compatible program to set the state of the relays and to display input status Specifications Relays e 8 Form C change over relays e Contact rating resistive load 15A 24VDC 15A 120VAC 10A 240VAC e Contact rating inductive load 5A 24VDC 5A 120VAC 5A 240VAC Isolated Inputs 4 isolated inputs minimum voltage 5V DC 5mA maximum voltage 24V DC 25mA Isolation 2500V peak 1775 RMS 1 second General e Power 9 12V 500mA via 2 1mm DC power socket ii centre pin ve Data and Power LED s Dimensions 140mm x 110mm x 35mm excluded screw terminals Serial port 3 way pin 2 pin 2 pin 3 gt pin3 pin 5 pin 5 maximum cable length gt 100m Format 9600 baud 8 data 1 stop no parity Operation There are 3 ways to communicate with the SPO RL8 from your computer 1 Using a terminal emulator program such as Hyper Terminal 2 The supplied Windows Program 3 Writing your own software Audon Electronics 123 High Road Chilwell
4. commands are used to control the relays return their status or read the inputs Each command consists of a string of ASCII characters followed by carriage return Enter J The character is output as a prompt to indicate the SPO RL8 is waiting for a command Each character received is echoed back On completion of each command good or bad a carriage return line feed combination is output followed by the prompt If the command or parameter is invalid the command is ignored and a is output before the next prompt Note e Commands are not processed until the carriage return character is received e Commands can be in upper or lower case e Relays are numbered 1 to 8 Relay number 0 zero indicates ALL relays e Inputs are numbered 1 to 4 Input number 0 zero indicates ALL inputs e Where a hex byte is used each bit within the byte indicates its corresponding relay or input Bit 0 indicates relay or input 1 bit 1 indicates relay or input 2 etc Nx Turn a relay ON where x relay number Eg N3 turn on relay 3 NO turn on ALL relays Fx Turn a relay OFF where x relay number Eg F3 turn off relay 3 FO turn off ALL relays Tx TOGGLE a relay on off where x relay number Changes the state of a relay ON to OFF OFF to ON Eg T3 toggle relay 3 TO toggle ALL relays Rhh Set ALL relays directly hh is a hexadecimal byte
