APPENDIX A: Distances, Data Rates, and Cable Specifications
Appendix A: Distances, Data Rates,
and Cable Specifications
For the best performance, use 22- or 24-AWG
unshielded twisted-pair (UTP) cable with a mutual
capacitance of 15.7 pF/ft. (51.6 pF/m) or less with the
SHM-B Sync. The table below shows the distances and
data rates attainable with this type of cable.
CAUTION!
Most types of UTP cable can be used with the SHM-B Sync
without having much adverse effect on its performance.
But, because it has much higher capacitance, shielded
twisted-pair (STP) cable will reduce the distance you can
run between SHM-B Sync units to as little as one-third of
the normal values shown below.
Data rate in bps Distance in miles (km)

9600 0.9 (1.4)
4800 1 (1.6)
2400 2 (3.2)
1200 3.5 (5.6)
