Connecting the
Vortex with Other
EchoFree Devices
If you are linking multiple Vortexes, you must use the EF bus to link the Vortexes to
each other. If you are linking a Vortex to other EchoFree devices, such as the EF200
Phone Add, for RS-232 control, use the ASPI bus. See Figure 4 below. The ASPI
Bus does not need to be terminated.
