Synchronization Input/Synchronization Output for DIO Synchronization Configuration. The DIO1
of BCD2 is also set as Digital Output for I/O Configuration and Synchronization
Input/Synchronization Output for DIO Synchronization Configuration. When DIO1 status of BCD1
changes, DIO1 status of BCD2 is synchronized as to DIO1 status of BCD1. In same way, DIO1
status of BCD1 is synchronized with DIO1 status of BCD2, too. In case of Output/Output
Synchronization, of two Parani-BCD110V3s connected on I/O profile, when one device changes
in DIO status by AT command, the other device is automatically synchronized.
* Each 5 DIO pin separately works. That means, each DIO pin can be set as Input/Output
Synchronization or Output/Output Synchronization.
Table 5-4 and Figure 5-3 below describes how both Parani-BCD110V3s of the I/O profile
connection works according to I/O Configuration and DIO Synchronization Configuration.
