APPLICATION NOTES
It is possible to make serial communications operate without following all the recommendations in this section;
however, the recommendations will promote greater reliability.
Host Computer
If possible, avoid using host computers which take their transmitter to a high impedance state (tri-state) when idling.
If it is unavoidable, then it is essential to use properly screened cable, such as suggested below.
Terminations
The drive farthest from the host computer should have a terminating resistor. The terminating resistor should be
changed to match the characteristic impedance of the cable, typically 100 to 150
W
. The resistors on all other drives
should be removed.
Cable Routing
Daisy chain one drive to the next; avoid spurs. Connect the host computer at one end of the daisy-chain. The host
computer's TX+ terminal connects to all the RX+ terminals along the daisy chain. Its RX+ terminal connects to all the
drive's TX+ terminals in the chain. This same pattern is followed for the TX- and RX- terminals. See Figure
H.6 for an illustration of the wiring scheme.
Grounding
Connect the screens of both pairs of wires to ground at the host computer. If possible, connect the host computer's
transmitter/receiver zero volts reference to ground.
