Use it in conjunction with our COM210, NL100 or RF400s
The MD485 RS-485 Multidrop Interface is replacing our MD9 Multidrop Interface. The MD485 is an intelligent RS-485 interface that is configurable to use any two of its three communication ports (RS-485, RS-232 and CS I/O) at a time. The MD485 device's primary function is to provide a connection to an RS-485 network using CS I/O or RS-232 ports. It can also provide an RS-232 connection to a datalogger's CS I/O port (CSDC or ME).
The MD485 is easily configured to handle multiple RS-485 protocols and all CSI communication modes. It can be set up to provide PakBus™ networking, MD9 emulation or transparent communication. PakBus networking incorporates collision New power supplies create more customer options The PS100 is a 12 Vdc, 7 Ahr power supply that can be recharged by solar panel or ac transformer. MD485 RS-485 Multidrop Interface: two ports at once avoidance and allows concurrent use of the CS I/O port. The MD485 can be used in conjunction with our COM210 phone modem, NL100 network link, or RF400 spread spectrum radios. Datalogger-to-datalogger communication is possible using MD485s, as is callback from a remote datalogger.
Connection between RS-485 links is made with inexpensive twisted pair cable. The MD485 communicates at 1200 bps to 115.2 kbps. It has a current drain of 1.4 mA in standby mode and 2 to 7 mA when communicating. Up to 4000 feet of cable can be run in an MD485 network.
Although the MD485s cannot be added to existing MD9 networks, the MD9 and accessories will continue to be available for our customers who have these systems.
