Up to eight (8) downstream (RS-485) boards (reader interface modules and/or input/output panels) and up to 16 off-board readers if eight (8) LNL-1320 boards are configured. -Reader port 1 supports up to eight (8) 2-wire RS-485 downstream devices. If this configuration is used, reader port 2 may be used to support one (1) on-board reader. Reader port 1 can also support multiple 2-wire RS-485 devices using OSDP protocol.Important: When powering any remote device(s) by the LNL-2210 SDC, care must be takennot to exceed the maximum current available. Cable gauge must also be evaluated. See the specifications section for details.24.1.3Input Circuit WiringTypically, these inputs are used to monitor door position, request to exit, or alarm contacts. Input circuits can be configured as unsupervised or supervised. When unsupervised, reporting consists of only the open or closed states.
