AES/EBU Output

		Figure 2-10AES/EBU output.
	Connect the positive (+) side of the line to pin 2 of the 3-pin
	female XLR connector and the negative (-) side of the line to pin
	3 of the connector. In keeping with standard wiring practices, the
	shield should be connected at this end; it should not be
	connected to pin 1 of the male 3-pin XLR connector or ground of
	the receiving end. The cable used should be 110Ω AES/EBU
	compliant cable such as MOGAMI 3080. See Figure 2-10 for
	more information.
	SPDIF Output
	The ISP-100 is not capable of providing SPDIF outputs.
Serial Communications
Serial communications with the ISP-100 can be accomplished either
through the DB-9 connector located under the front panel security
cover or through the RJ-45 connector located on the rear panel. The
computer connected to the ISP-100 must have a free COM port			When tuning the
(1-4). Communications with the ISP-100 will not work properly if the			system with a
COM port is shared with another device such as a TEF™ analyzer. It			computer controled
is important to set the serial port selection switch located under the			analyzer use a
front panel security cover to the serial port used. The cable used			separate computer
should be of low capacitance and suited to data communications.			for the analyzer.

The serial port selector switch should be set in the down position. If the PC’s COM port is a DB-25 connector, wire the cable according to Figure 2-11. If the PC’s COM port is a DB-9 connector, wire the cable according to Figure 2-12. A snap-on
