PMAC-Pack
56 PMACPack Custom Configuration
E86: Host Interrupt Signal Select
This jumper works together with E55-E65 and E76-E84 to set the mapping of PMAC information to host
PC bus interrupt lines. (It is of no relevance to PMAC-Pack operation.)

E87
F4 E87 should be removed for normal operation of PMAC-
Pack with internal opto-isolated supplies. Jump pin 1 to
pin 2 to allow GND to come from bus or PMAC-Lite’s
TB1 port (ties +5 logic and
)
15 analog power supplies
together. Defeats OPTO coupling.
Note:
If E87 is changed, E88 and E85 must also be
changed.
Also, see E90.
No jumper
E88
F4 E88 should be removed for normal operation of PMAC-
Pack with internal opto-isolated supplies. Jump pin 1 to
pin 2 to allow -14V to come from bus or PMAC-Lite’s
TB1 port (ties +5 logic and
)
15 analog power supplies
together. Defeats OPTO coupling.
Note:
If E88 is changed, E85 andE87 must also be
changed.
Also, see E90.

F3 Jump pin 1 to 2 to allow "A+15V/+V" on PMAC-LITE
J8 (JEQU) pin 9, to tie to "A+15V" on J11 (JMACH1)
pin 59.
This jumper must be installed to allow "A+15V" to
power the "OPTO" switch sensor inputs (including
limits) from the same OPTO-power supply that powers
the amplifier output stage.
Also see E90.

C11 Jump pin 1-2 to allow PMAC-Pack internal supplies to
power "OPTO" switch sensor inputs (including limits).
Jump pin 2 to 3 to allow "+12V" from PC bus
connector P1-pin B09 to power "OPTO" switch sensor
inputs (including limits). Optical isolation is then lost.
