Tap Specifications
Overview Modicon MA-0185-100 Taps connect the drop cables to the main trunk cable and
isolate the RIO drop adapter from the rest of the network. This tap is nondirec-
tional—it allows signals to be propagated in both directions along the trunk cable.
An MA-0185-100 tap has one drop port and two trunk ports.
An MA-0185-100 tap is supplied with a plastic isolator on its back. The tap isolates
the drop adapter from the trunk cable by 14 dB.
Unused ports on the taps must be terminated with a Modicon 52-0402-000 Port
Terminator, and the last (trunk-out) port of the last tap on the network must be
terminated with a Modicon 52-0422-000 Trunk Terminator (see Network
Terminators, p. 83).
Note: Although the trunk ports are labeled IN and OUT, these labels can be
ignored—i.e., the tap is not directional.
