8.6.5 PROPER DSAI INSTALLATIONS

Here are some examples of DSAi installations that will work reliably, both avoiding loops and keeping EIA- 485 running well. These can be used as a basis for larger and more complex installations.

PC

DSA

PILOT

485	CM1	SLink
	DSA "A"
	PLink

485	CM1	SLink
	DSA "B"
	PLink

485	CM1	SLink
	DSA "C"
	PLink

485	CM1	SLink
	DSA "D"
	PLink

EXAMPLE 1:

This is a simple EIA-485 network connected directly from the PC, which runs DSAPilot, to DSAi "A" and then daisy- chain fashion to "C". Because they are in close physical proximity, Link cables are used to connect the control data and audio to "B" and "D". The termination switch for "C" is on. The termination switch should be off on all the other modules.

EXAMPLE 2:

This is a standard CobraNet connection. Just like computers connected using Ethernet, each module, whether used singly or in a cluster, requires its own a connection to a network switch. No Link cables are used. The DSAPilot PC communicates to all DSAi modules through the serial bridge in the CobraNet Unit.
