Figure 10. Format of Outcut Word to Universal Keyset from Digital Output Multiplexer
(a) Field C is a message selection code for a particular PRO
and shall be in the storage location allotted to that PRO. There are nine Field A codes required
for this purpose.
(c) Field C contains illumination control data for a particular
group of four computer Monofunction switches and shall be stored in the appropriate register.
There are two Field A codes required for this purpose since there is a total of eight computer lit
Monofunction switches.
(d) Field C contains data for the illumination control of the
colored background messages on a particular group of four Matrix Switches and shall be stored in the
appropriate register. There are two Field A codes required for this purpose since there is a total of
eight Matrix switches.
(e) Reset the storage flip-flops for PRO's 7-9.
In addition to one of the operations described above, Field A shall
enable or disable (depending upon Field B) one of the test loops in the UKL.
(2) Field B - A logical "l" shall enable the test loop specified by
Field A. A logical "0" shall disable the test loop specified by Field A; this bit is stored in the same
register as the Field C bits.
(3) Field C- The interpretation and storage location of Field C de-
pends upon Field A.
Universal Keyset Logic to Digital Input Multiplexer - Communi-

cations between the UKL and the DIM shall be In accordance with 3.5.1.4.1.
Digital Output Multiplexer to Universal Keyset Logic - Communi-
3.5.1.4.4.5.4
cations between the UKL and the DOM shall be in accordance with 3.5.1.4.2.
Clock Signal From Maintenance Control Panel Logic to Universal
3.5.1.4.4.5.5
Keyset Logic- - A 10 millisecond clock signal for the UKL shall be generated in the MCPL.
Enter Signal from Universal Keyset Logic to Digital Input Multi-
3.5.1.4.4.5.6
plexer - An Enter signal shall be generated within the UKL when the subunit has data for transmission
to the computer. This Enter signal shall be transmitted to the DIM.
