The Black Pear can replace or work in parallel with a Toshiba central controller. Each refrigerant system must have a separate line address and the network address (Configuration Item 03) must be set between 1 and 64.

1 to 24. The Base Slave Address can be adjusted from 1 up to 200. A setting of 200 means the Black Pear will respond to msgs for slaves 200 to 223. This is useful to prevent address clashing when the Black Pear unit is attached to a serial communications network containing multiple Modbus devices. -

Page 22: Trend Interface (Tt-64X Only)
TT-64x Fig. 7 Trend System Example The Black Pear connects via Ethernet to a CNC or the virtual CNC port of a Trend IQ outstation, and uses sensors, switches and knobs defined in the IQx memory to mirror a range of HVAC parameters, making them available on a Trend network. -
Page 23: Trend Process Description
Some Trend systems will generate ‘network alarms’ due to the repeated connection and disconnection of the Black Pear to the CNC. Setting the CNC Usage = 0 will allow a single Black Pear to remain connected to the CNC, thus preventing these alarms from being generated. -
Page 24: Trend Iqx Outstation Configuration
298 to 301 302 to 305 The Black Pear can be configured to enable only those objects of interest to the user, therefore reducing the memory overhead required in the IQ outstation. Any objects enabled in the Black Pear which aren’t defined in the Trend outstation will simply be ignored during the polling sequence. -
Page 25: Parameter Settings
8.3 Parameter Settings See the table in Section 7.4 for a list of valid parameter settings. Notes: As of firmware v2.29, the return air sensor and the setpoint knob will contain temperatures valid to 1 dp (with 0.5 C resolution). Setting the setpoint to 1 dp is reliant on the HVAC unit accepting setpoint commands to this resolution. -
