CAMO ~ CAM2, CAM INT are the transport cam position detecting input pins and the
position is input at LOW level.
LM1 and LM2 are output pins for controlling the loading motor which rotates the cam.
When LM1 goes LOW, UI 4-10 goes to HIGH, and when UI 4-2 goes LOW, the loading
motor starts rotating. When LM2 goes LOW, the rotation will reverse. The motor will
stop when both LM1 and LM2 go to HIGH. When the STOP button is depressed during
loading of the transport, a LOW level is output from LM2 and the loading motor will
rotate. When the cam position detecting input CAM INT goes to LOW level, LM1 will go
to LOW to apply the brake on the cam. If the CAM INT input goes to HIGH, both LM1
and LM2 pins will go to LOW and the cam will stop.
5) STOP-O (U101-25), RWD-0 (U101-24), FF-0 (U101-23), PLAY-0 (U101-22)
These are tally output pins. LOW is output during the various modes.
6) LIFTER-I (U101-59), PLAY-I (U1O1-58), REC-I (U101-57), PLAY2-I (U101-56), FF-I
(U101-55), RWD-I (U101-54), STOP-I (U101-53), EDIT-I (U101-51), ERASE-I (UI 01-
50), SPOT-I (U101-49)
These are parallel input pins to the main unit switches. They are active at LOW level.
7) SHUT OFF (UI 01-60)
This is the shut off pulse input pin. A LOW level will be input when both left and right
tension arms are down. The transport will then be in the loading state.
8) TR-STOP-O (UI 01-21), SR-STOP-O (UI 01-20)
Outputs to switch off the takeup and supply reels.
Reel is stopped at HIGH level output.
9) PUNCH I/O-I (U101-18), LOC/PLAY-I (U101-19)
Foot switch input port. Active at LOW level.
10) 2.4K-I (U101-4), 4.8K-I (U101-3), PITCH-0 (UI 01-79)
HIGH level will be output when pitch control is switched on at PITCH-O. 2.4K-I and
4.8K-I are inputs for displaying of pitch by counting and displaying 4.8K-I using 2.4K-I
as the reference.
