Connecting The Equipment
Connect the cabling to the ATI-D-1PT as shown in the diagram on the next page.
Be careful when connecting the wiring between the common equipment and the ATI-D-1PT. Be sure to
connect the digital station port to the COMMON EQUIPMENT (KSU) jack on the ATI-D-1PT. Damage
to the ATI-D-1PT could occur if this wiring is connected to the IST jack.
While a grounding wire is not required for operation, one is desirable for decreasing radio frequency interference
and electrostatic discharge susceptibility. The ATI-D-1PT has a grounding stud for this purpose. Connect a #10 or
#12, insulated, solid copper wire between this ground stud and an earth ground.
Checking The Installation
Use a voltmeter to check for the presence of voltage on the ATI-D-1PT IST jack.
1. Be sure the wiring between the ATI-D-1PT and the common equipment station ports is properly installed.
2. Measure for DC voltage on the IST jack:
•
Measure between TIP leads and common equipment grounding stud.
•
Measure between RING leads and common equipment grounding stud.
•
Measure between TIP leads and RING leads.
The measured voltage must be within following limits (with the IST device on-hook):

Tip to Ground
Ring to Ground

CAUTION
-1 to +1 VDC
-27 to -38 VDC
+28 to +37 VDC
(The TIP lead is positive with respect to the RING lead.)
