    Otherwise you run the risk of damaging the RTS-424. If the same power source is used for more than one RTS-424, ensure that the transformer is properly sized for the rated VA and ensure that the same polarity is observed from device to device. Each RTS-424 is rated for 1.5 VA Document Edition 1.1...

  • Page 6: Power

    Toshiba based Application Controllers loaded with V2 firmware The RTS-424 requires a 24 VAC or 24 VDC @ 1.5 VA power supply, typically an isolated Class II transformer. Up to 8 RTS-424s may be connected to the same transformer, providing the transformer is properly sized, including line losses, and polarity is observed between devices (in regards to 24~ and GND).

    • Nominal velocity of propagation of 66% or higher *RTS-424 networks have also been tested to a limited degree on unshielded 18 AWG wire with no ill effects. For new installations it is recommended to use the better cabling mentioned above as this will help to avoid any potential network communication problems and allow for future upgrades to V3 MS/TP BACstat networks.
