    1 nl100/105 network link interface 1. Introduction the nl100 and nl105 network link interfaces are devices used to communicate with campbell scientific dataloggers using an ethernet 10 base- t communications link. The nl100 includes a cs i/o port (see appendix a) and an rs-232 port for communication...
