BUILDING YOUR SYSTEM WITH MULTIPLE VOR-

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.
