Synchronous Communication Protocol & Auto ID Setup
This function allows the auto setup of communication protocol in extension module DTC2000 and DTC2001 following the communication
protocol set in the DTE main unit. The station IDs of DTC decrease. See below for the steps.
1. Set the auto communication ID of DTE as “1” (communication address: H10F8).
2. Switch off DTE. Connect DTE with extension module DTC2000, DTC2001 and switch on DTE again.
3. Default communication protocol: 9,600bps, 7 bits, Even, 1 stop bit, communication address = 01.
4. This function will consume 3 ~ 5 seconds more when you switch on DTE.
PV value adjustment

CT and adjustment (Current Transformer)
Function:
DTE10T offers maximum 4 channels of CT (CT1 ~ CT4), responsible for monitoring the current in INA.
Each CT group can be set up independently. With alarm outputs, when the detected current value is
beyond the allowed range, the corresponding alarm will be enabled.
Slot INA offers 4 channels of input, and CH1 ~ CH4 correspond to the current detected at CT1 ~ CT4.
Hardware requirement: Accessory DTE2CT inserted in the slot AUX.
How to operate:
1. Enable the CT function: Write 1234H into the address 47F1H and then 0004H into address 4824H.

Notes:
The flag to enable CT is at bit2 of 4824H. Write 0004H to bit2 to set it on.
If the “multistate” function is enabled, for example, writing in 0024H means enabling bit5 and bit2 at the same time.
You can only choose to use either the CT or EVENT function.
If there is already a set value in 4824H and you would like to modify it, reset it to 0 before you set up a new value.
CT auto adjustment: Insert CT card without terminal first, write 1234H into the address 47F1H and then write 1234H into address
482CH.
Reading address 482C, if response 0000H means adjustment finish, if response 0001H means in adjustment status not finish.
