The PIU functions as an interface between the host application (irrigation SW and HW) and the Piccolo–XR units. The PIU and Piccolo-XR are portable devices, which are used in fixed installations. The PIU uses one of its communication ports to link to the host application and radio communication to link to the Piccolo–XR units.
Unit RS485 Piccolo RS232 Interface Unit Piccolo-XR Units I/O's Figure 1 DIOS –General System View The battery-operated Piccolo–XR unit is available in various models with different options of Inputs and Outputs. The Piccolo–XR unit can operate DC latch solenoids (outputs), read status and calculate flow of dry contact meters (inputs).
Introduction PIU - Piccolo Interface Unit The Piccolo Interface Unit (PIU; see Figure 2) is connected to the IRRInet Field Unit (FU) via RS232 or RS485 serial ports. Each PIU supports up to 256 Piccolo–XR units, with any available I/O combination, limited by the capacity of the IRRInet software only.
Introduction Figure 2 PIU – General View Piccolo–XR The Piccolo–XR is an intelligent, microprocessor based unit that can be used to monitor and control local units in a multi unit communication network. Piccolo–XR units communicate data to a PIU while functioning as intelligent nodes in Distributed I/O monitor and control systems.
For safety handling instructions, see the Product Safety and RF Energy Exposure Booklet for PIU and Piccolo XR Units, Motorola publication no. 6802974C70, which is distributed with the devices. The radio frequency band used by the DIOS system has not been harmonized throughout the entire European Economic Area (EEA).

INSTALLATION General SAFETY SUMMARY The PIU and Piccolo–XR must be installed by qualified and authorized technicians, specifically qualified to handle high voltage if the installation C a u t i o n involves high-voltage connections/installations. If the PIU will be installed outdoors, an outdoor plastic housing complying with UL60950 standard clause 6 is required.
Installation Before installing the PIU, verify that there is sufficient space around the unit according to the specific installation. Mounting the PIU On A Wall Using Screws 1. Secure two screws (not supplied) of maximum 0.37" (9.5 mm) head size to the wall, 3.256" (82.7 mm) apart. The wall-mounting template in Appendix D can be used to determine the space between both screws.
Installation Mounting the PIU Using a Bracket 1. Using four M3x6 or M3x8 screws, attach a bracket (not supplied) to the back of the PIU. The upper two bracket holes must be 3.19" (81 mm) apart, and the lower two bracket holes must be 2.40" (61 mm) apart and 2.13"...

ON/OFF switch, and the unit cannot be powered on...
The PIU can be powered by various types of supply sources: Internal (9VDC) battery; External 6V or 12V DC battery; Motorola power supplies – controllers. For example: IRRInet XL, IRRInet XM, IRRIcom, MOSCAD; 24VAC. The unit DC voltage range is 6 to 16 volts. NOTE!
Installation Installation of an Internal Battery 1. Release the screw at the top of the battery chamber door, and slide the door out, as shown in Figure 10. 2. Connect the 9V battery cable (FKN8204B) to the DC power input connector on the back of the unit. 3.
Installation External Battery Power Connections The unit must be powered by a limited power source (12V DC) in accordance with standard UL/IEC 60950-1. See Power in Appendix A below. C a u t i o n This connection is used for normal operation of the PIU, when radio communication is required, or when RS485 or RS232 ports are used.
Installation External Power Supply Connections Use the applicable cable from the V152AH PIU installation kit to connect the PIU to Motorola standard controller power supply. 1. Release the screw at the top of the battery chamber door and slide the door out, as shown in Figure 10.
Installation 24VAC Power Connections The PIU must be connected to a power source equivalent to one or more of the following: a. A listed Direct plug-in unit. C a u t i o n b. A Class II power source (defined by the National Electrical Code (NEC) and the Canadian Electrical Code (CEC).
Installation PIU Antenna Connection Flexible Antenna: Attach the flexible monopole antenna to the antenna connector at the top of the unit. See Appendix C for detailed information. Pole Antenna: Attach the FKN8258B antenna cable to the antenna connector at the top of the unit. Connect the other end of the antenna cable to a customer-supplied pole antenna.
Installation The Piccolo–XR unit can be attached to any vertical or horizontal surface using screws. Before mounting the Piccolo– XR, verify that sufficient clearance is left around the unit. Allow 8" (20 cm) clearance off the bottom of the Piccolo–XR case for the user cable and 6.3"...
