105U-G Wireless Gateway User Manual
Page 49 © August 2003
These clock registers are used by the 105G for the real-time clock trigger. The host device
can read these registers.
Item Read Location Set Location
Days 4330 4340
Hours 4331 4341
Minutes 4332 4342
Seconds 4333 4343
The host device can also set the 105G clock at any time by writing to another set of registers
4340 – 4343. These registers are normally zero. When a value is written into one of these
registers, the 105G copies the value into the corresponding clock register, and then sets the
“Set” register back to zero. For example, if the host device writes a value of 7 into Reg 4341,
the 105G will write 7 into 4331 and set 4341 back to zero.
4.4.5 Change-of-State
If a value in the block changes by more than the sensitivity amount, then the block message
will be sent. The sensitivity values are set under the “Sensitivity” option as per section 4.5.
This can only occur for Write mappings.
A delay time can be entered to reduce the number of change triggers in active systems. For
example, if 20 seconds is selected in the “Delay” window, then the change message will be
sent 20 seconds after the change-of-state occurs - if other changes occur during the 20
second period, all of these changes are sent in the one message.
The delay time can be set from 0 – 254 seconds.
