The N-485-API-2 (Access Control Panel Interface) provides an RS485 communication interface to your existing N-1000-II. The N-485-API-2 interface N-485 converts the 20mA current loop supplied by the N-1000-II to an RS485 signal which can be used on the multi-drop line. Northern's RS485 multi-drop line can support up to 31 RS485 nodes per system COM port. The N-485-PCI-2 and N-485-HUB-2 interfaces convert RS485 to RS232, and both come with plug-in power supply. The N-485-PCI-2 is used at the computer N-485-API-2 for a direct connect system. The N-485-HUB-2 is utilized with an auto-dial modem at a remote location. The N485PCI2L is used to connect the LANSRL100 (Ethernet to 232) to the N-1000 RS-485.
