ONYX Series Direct Panel Interface DPI 232 Direct Panel Interface is a specialized modem extending EIA 232 serial data links to remotely located con panels and or peripherals DPI 232 is used with ONYX Series NFS 320 NFS2 and NFS2 640 intelligent Fire Alarm Control Panels and NCA 2 Network Control Annunciator Please refer to the DPI 232 Manual PN 51499 for sup legacy products include extending distance between FACP and peripheral device CRT printer FACP and NOTI connection module Network annunciator and NOTI connection diagrams of applications and connections charts are in the DPI 232 Manual Utilizes two copper unshielded twisted pairs of 16 to AWG 1.3 to 0.13 mm wire Capable of carrying full duplex transmission with data rates up to 57.6 Kbaud in each direction over a distance of up 10,000 feet 3048 m Each full duplex transmission link requires one DPI 232 on end of the two pairs Each wire pair is connected to transmitter terminals TX of the DPI 232 on one end and to the receiver terminals of the DPI 232 on the other end Each DPI 232 supervises for ground faults on the wire pair to TX and terminals The ground fault has an LED indicator as well as Form C trouble Panel peripheral terminals are electrically isolated from the pair terminals Equipped with a power saving switch that allows power at the lower data rates of up to 9,600 baud data rates than 9,600 baud require setting switch to Plugs into a 120 VAC wall outlet and supplies 24 VDC to the DPI 232 modem This power supply must be when the modem is not being powered directly from a or other UL Listed
