Specifications

Features

• Utilizes two “dry copper” unshielded twisted-pairs of 16 to 26 AWG (1.3 to 0.13 mm²) wire.
• Capable of carrying full duplex transmission with data rates of up to 57.6 Kbaud in each direction over a distance of up to 10,000 feet (3048 m).
• Each full duplex transmission link requires one DPI-232 on each end of the two pairs.
• Each wire pair is connected to transmitter terminals (+TX, – TX) of the DPI-232 on one end and to the receiver terminals (+RX, –RX) of the DPI-232 on the other end.
• Each DPI-232 supervises for ground faults on the wire pair connected to +TX and –TX terminals. The ground fault detector has an LED indicator as well as Form-C trouble contacts.
• Panel/peripheral terminals are electrically isolated from the twisted pair terminals.
• Equipped with a power-saving switch that allows power conservation at the lower data rates of up to 9,600 baud. Higher data rates than 9,600 baud require setting switch position to “57.6”.
• Plugs into a 120 VAC wall outlet and supplies +24 VDC to power the DPI-232 modem. This power supply must be used when the modem is not being powered directly from a FACP or other UL-Listed power-limited power supply. Listed for fire protective signaling.
