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 110

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
(1-4). Communications with the ISP-100 will not work properly if the
COM port is shared with another device such as a TEF™ analyzer. It
is important to set the serial port selection switch located under the
front panel security cover to the serial port used. The cable used
should be of low capacitance and suited to data communications.
Front Panel RS-232
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
