Chapter 3: Option Selection FILTER RESPONSE SWITCH Jumpers are used to select input filtering on a channel-by-channel basis. W hen jumper FLT0 is installed, additional filtering is introduced for input bit 0, FLT1 for bit 1, etc. This additional filtering must be used whe n AC inputs are a pplied. -

Connections The signal assignment to each of the screw terminal board’s pins are as follows: ‘Isolated Input’ Signal ‘Relay Outp ut’ Signal Terminal Block PCB Terminal Block PCB Relay 7 - normally closed Relay 7 - comm on +PWR* Relay 7 - normally open +PWR* Relay 6 - normally closed Relay 6 - comm on... - Page 10 +PW R*: Power is power from a local power supply. The voltage can be anywhere from 7.5 VDC to 16 VDC. Higher local power, 24 VDC for example, can be used if an external zener diode is used to reduce the voltage applied to RIOD24.

Page 11: Chapter 4: Software
Chapter 4: Software General You received ASII-based software on CD for use with W M-IIRO-8. ASCII programm ing permits you to write app lications in any high level language that supp orts A SC II string fu nction s. The comm unication protocol has two forms: addressed and non-addressed. Non-addressed protocol can be used when only one W M-IIRO-8 is in use. -

The pod can set a change-of-s tate flag for any input th at has been configured to do so. This comm and will read then reset that bit. Therefore, this comm and will always return "N[CR]" unless the T c om m and has first been u sed to enable cha nge -of-s tate detec t for an y given b it.

Error Codes The following error codes can be returned from the pod: Invalid channel number (too large, or n ot a num ber. All channel numbers m ust be between 00 and 17 , in hex. (0-24 decima l)) Im prop er Syntax. (Not enough para m eters is the usua l culprit) Channel number is invalid for this task (For example, if you try to output to a bit that is set as an input bit, this error code will occur) Parity error. -
