215IF Module
This section describes how to connect cables inside the control panel of the 215IF Module
mounted in an MP900-Series Machine Controller.
Fig. D.1 215IF Transmission Line Connection Example (JC215-01)
• For connections between Communications Interface Modules, connect the MR-8LM(G)
terminals with the same number using in-panel cables.
Connect pins 8 and 1 of the MR-8LM(G) connector to SRD+ and SRD-, respectively.
• Install the JC215-01 on the input and output sides of the control panel, and connect the
in-panel and panel-to-panel cables to the JC215-01.
• JC215-01 signal terminals: Both input and output are possible between terminals 1 and 2
or between terminals 3 and 4.
• Where the JC215-01 is installed at the end of the transmission line, always install a termi-
nating resistance (75 Ω) between JC215-01 terminals 1 and 2 or between terminals 3 and
4.
• Connect only one end of each in-panel cable or panel-to-panel cable shield to terminal S
of input JC215-01 or output JC215-01, and connect terminal E to terminal Es in the con-
trol panel using a 1.25 mm
2
ground wire.
