Appendix 10 – AVIDdirector Jumper Settings
The jumper settings on the AVIDdirector main board vary between revisions. Please check your AVIDdirector's
revision letter to correspond the correct jumper settings. The 3rd letter of the serial number indicates the revision.
Example, A0C17QC00014 is a Revision C board.
In the descriptions, Vin refers to the input voltage to the AVIDdirector, which is between 8 to 18 VDC and normally
12 VDC. VRail is the output on pin 12 of the 12-pin Phoenix Connector and pin 20 of the DB-37.
Note: The default setting for Revs C, D, and F are DB-37, pin 20 is Vin. DB-9 pin 9 is +5V.
The settings according to revision letter are:
Rev A: 12-pin Phoenix connector
has VRail on pin 12. Inserting JP1
connects Vin to VRail, which also
drives the High Voltage / Current
(HVC) outputs. With JP1 removed,
the VRail (maximum voltage for the
HVC was SUPPLIED by VRail pin
12).
DB-9 pin 9 connects to Ring Indicator
input.
Rev B: 12-pin Phoenix connector. JP1 on 1-2 provides Vin on the
VRail connection. JP1 2-3 provides +5V on VRail. Removing JP1
allows external VRail to power the HVC (like on Rev B). DB-9 pin 9
provides +5V at 200ma.
Rev C: JP1 is the DB37 pin 20 jumper
that supplies the VRail output voltage
with maximum current of 0.5A. JP1 1-2
connects VRail to Vin (nominally
12VDC), JP1 2-3 connects VRail to
+5V.
DB-9 pin 9 connects to +5V at 200ma.
