A66L–0001–0298: Oki Electric Cable Co., Ltd. (#24AWG pair x 2, #24AWG x 10, external cable diameter: 8.5 mm), or
A66L–0001–0284#10P: Oki Electric Cable Co., Ltd., Hitachi Cable, Ltd. (#28AWG pair, external cable diameter: 6.2 mm,
Conductor registance: 88.9Ω/km)
Cable connection (J129)
(NOTE 1) ATCH1
(NOTE 1) ATCH2
1 ATCH1, ATCH2, *SELn
ATCH1 and ATCH2 can be used as DI signals for detecting whether a detachable LCD/MDI is
attached to the connection panel (See Subsec. 8.5.5). ATCH1 and ATCH2, when unused,
need not be connected.
Connect only necessary signals out of *SEL0 to *SEL7 according to the number of devices.
The A66L–0001–0298 cable cannot be used if seven or more signals are being input from
ATCH1, ATCH2, and *SEL0 to *SEL7. In such a case, use cable A66L–0001–0284#10P.
2 The external diameter of the cable used with connector CA50 is 8.5 mm. If the external
diameter of the cable is less than 8.5 mm, increase the diameter to 8.5 mm by using
heat–shrinkable tube or taping at the connector joint to ensure a dustproof connection.
Using a drain wire, connect CA50 (05) to the FG terminal of the connection panel.
Connect the FG terminal of the connector panel to the frame ground by using a twisted–pair
cable, 100 to 300 mm long and with a cross–sectional area of at least 2 mm
