AST RESEARCH TECHNICAL BULLETIN TB-0025 7-9-84
PCNET II TERMINATOR ALTERNATIVE
At times it may be desirable to move nodes (network workstations)
to different locations along the trunk cable. If a terminated
node (jumper block T in position 2) is exchanged for a non-
terminated node (jumper block T in position 1) both PCs would
have to be opened to change these jumpers. The alternative is
to terminate the ends of the trunk cable and leave all the PCNet
II boards non-terminating. The termination must be done at the
two very end tap boxes using a 120 ohm resistor wired as seen in
figure 1. Type and wattage of the resistor is not important
although larger wattage resistors may not fit inside the tap box.
The resistors are not supplied by AST, but are available from
most electronic part suppliers.
