Note: When there is only one RS-485 MTX-15 terminal in the
system, DIP Switch 1 must be in the ON position to enable the
termination resistor.
Note: If the distance between the terminal and the host PC is more
than 50 feet, two junction boxes will be required (see the next
page), or you can use an RJ-11 coupler with a RJ-11
extension cable, not to exceed 3,950 feet.
Multi-terminal (maximum of 31) applications require the DIP Switches to
be OFF in all but the last terminal on the communications line. DIP
Switch 1 of the last terminal must be set to ON to enable the termination
resistor so that all the terminals can properly communicate with the Host
PC. The terminal settings and connections between the PC and
terminals for this application are as follows:
