(1)When using the CRT sharing function, mount the device No. selection
switches on the cabinet.
(2)The total length of the cables (J129, J130, J126, J45 x n) between the
detachable LCD/MDI and Power Mate units must not exceed 50 m.
(3)Cables J129, J130, and J132 also serve as a 24 VDC power supply line
for the detachable LCD/MDI. The 24 VDC power is subject to a
voltage drop corresponding to the total resistance of the 24V and 0V
lines. Taking this voltage drop into consideration, determine the cable
length so that 24 VDC "10% is available at connector CA50 of the
(4)Connect the display link to a terminating resistor in the last display
link adapter (see Section 8.1.9).
(5)The connections from Power Mate #0 to Power Mate #15 are the same
as those for the CRT/MDI unit.
(6)While the power is on, cables can be attached/detached to/from those
connectors on the connector panel that are shaded (
) in the above
figure. For the other connectors (such as CA50 and JD41), cables can
neither be attached nor detached while the power is on.
