2. Product Overview
The Black Pear TXIO enables third party equipment to be controlled and monitored with the
Smart Touch central controller and Toshiba versions of the Black Pear BMS interface.
Each TXIO can be given a TCC-Link central address and will then appear on the Smart
Touch or Black Pear interface as a simple unit with On/Off, Error and Return Air parameters.
On/Off is provided as a relay output rated at 230v 1A
Adigital input provides an error monitoring facility with the error being reported as a C12. The
polarity of the input is selectable.
Return air may be monitored by connecting a 10K301 thermistor.

3.1 Power Supply
The TXIO requires a 100-240v AC supply and has a consumption not exceeding 2VA. The
internal fuse is rated T630mA.
THIS EQUIPMENT MUST BE EARTHED
3.2 HVAC Communications Network ( TCC-LINK )
Can be connected to either U1/U2 or U3/U4 networks.
These are non-polarized.
Do not connect to the remote controller network.
3.3 Relay Output
The relay output is rated at 230V 1A. Normally-open and normally-closed terminals are
provided.
3.4 Error Input
This input accepts a volt-free contact. The polarity of the ‘active’ state is selectable via a
shorting link. See section 4.2.
3.5 Thermistor Input
Connecting a 10K301 thermistor to this input allows a temperature to be monitored by the
central controller or BMS interface.

4. Configuration
4.1 S1 Bitswitch Function
S1-1 On = 100 ohm terminator connected across the TCC-Link lines
Off = No terminating resistor.
Note:- Only one terminating resistor should be enabled per network
S1-2 On = Auto Restart (retain the I/O state as it was at power down)
Off = Start in the OFF condition

The address set by S1-3 to S1-8 is used for both the central TCC-Link address and also
for the Unit address in the Line/Unit addressing mode.
The Line address for the TXIO interface is always 29.
4.2 S2 Link Function
S2 controls the polarity of the ‘Error’ input signal.
Normally open signal (Closed=Error) Link S2-1 to S2-2 (bottom pair of pins)
Normally closed signal (Open = Error) Link S2-2 to S2-3 (top pair of pins)
