DKSC-16 Extended Loop LengthModification
For longer station loop lengths (up to 154 ohms/3000
ft.), if necessary, an optional external power supply
with the following characteristics can be connected to
the DKSC-16 termination block:
•36VDC
•120mA per keyset (1.92A for all 16 circuits)
This option is available only on DKSC-16s that are at
revision level “2.0” or later or that have been modified
andlabeled with FSM100995. The exte rnal power sup-
plyis connected to pins 50 (+36V, V/SL) and 25 (GND,
SL/V) on the terminationblock. In addition, the strap
onjumper JP1 must be placed over pins 1 and 2 to en-
able the external power supply.
New Voice Processing Card (VPC)Models
The 4-Port and 8-Port VPCsdescribed in the Issue 4
manual have been superseded by newer “mini-size”
models. Otherthan their smaller size, these new mini-
size cards install and function the same as the original

CPU020/PCM Card Software InstallationInformation
Thefollowing information will be useful when loading
CPU 512 Master and Slave software.
New Warning Message: A warning message will now
appearif you attempt to load CPU 512 Master software
withouta CPU 512 Slave Card installed andcommuni-
cating.The message says, “WARNING, the SlaveCPU
is off-line. Uploading code without a Slave CPU may
causeserious system problems. Do you wish to contin-
ue with the upload?” You can continue the upload by
selecting Yes or abort the upload by selecting No.(If
you select Yes,you must install software on the CPU
512 Slave Card before it will function. Refer to page
3–73 in the manual for details.)
Checking Validity of Software On A Slave CPU:
You can use the following procedure to check the
validity of software on your CPU 512 Slave Card:
(1) Attach a terminal (or a PC using terminal emu-
lation software) to the serial porton the secon-
dary CPU in slot24. (Communication parame-
tersa re: 9600 baud, no parity, 8 bits, 1 stop bit.)
(2) Turn off the secondary cabinets (slots 17–31).
(3) Turn on the secondary cabinets whilewatching
the power-up messages on the terminal. You
should see:

to the appropriate 16-bit (full-size)slot, and
set the bracket and screw aside. (Refer to
Figure3–57 on page 3–111 in the manualfor
a sample card slot arrangement.)
b. Check to make sure that a jumper strap is
placed over the middle two pins (IRQ9) of
interrupt jumper J503 (refer to drawing on
page 40).
c. Ensure that the eight address selection DIP
switches (SW1) are set to 320 hex: 1–3 &
5–6 = ON (down); 4 & 7–8 = OFF (up).
d. Check to make sure the two MVIPclock ter-
mination DIPswitches (SW2) are set in the
OFF (up) position.
