Micro-USB port is reserved for FW upgrading (USB cable is not included
in the kit).
Only Control Rooms are allowed to perform this operation.
K:
TTL 3V type Serial port (‘K’).
Reserved for XT-KPAD wired keypad connection.
Alternatively it is possible to connect i-Button accessory through ‘1-wire’ serial,
or OEM customized accessories following predefined X-10 communication
protocol.
S:
RS-485 type Serial port (‘S’).
Reserved for
Input 5 (Positive)
connection.
Alternatively, by setting dip-switches shown in the figure, it is possible to
connect XT-HUB multifunctional accessory.
Note:
Upon request, it is also possible to covert Serial port 'S' from default
RS-485 to TTL 3V format for connecting XT-MINI HUB I/O expansion box (HW
modification on X-10 PCB is required).
Power/Inputs/Outputs ports connection:
P/I/O:
10 pins connector combining Power, Inputs and Outputs signals. Up to
4 Inputs (1 Positive/ 3 settable to Positive/Analog or to Negative),
and up to 4 digital Outputs (all Negatives) can be managed through this port.

IG Function:
By connecting Red and Black wires to Positive and Negative
signals of the vehicle main battery the devices can detect “Engine On” &
“Engine Off” status avoiding to connect White wire (Input 1) to
ACC/Ignition
Key
signal. After enabling IG function, Input 1 becomes available for other
purposes.
In order to enable this function please contact your reference Control Room
providing the exactly voltage levels measured on vehicle main battery when
“Engine On” and “Engine Off” conditions.
