3-1 Data Processing and Operation Modes

 OR mode

This mode is used when reading BCD output from multiple DL-RB1A units with one external device.

Set the external device so that there at least 2 ms before turning DRQ input on and after

turning DRQ input off.

 Sample wiring

When sending BCD output from two DL-RB1A units to one external device.

- Perform OR wiring from the two BCD outputs to the external device input.

- Perform OR wiring from the two strobe outputs to the external device input or wire each input

independently.

- Wire both of the DRQ inputs independently from the two outputs on the external device (OR

wiring cannot be performed with the DRQ).
