Cable Spec 21 - Benderlink for Chiyoda KEINS - MQ85 Inner Bender Cable

This is the wiring schematic for Cable Spec 21 used in MQ85 benders.
This is a 15 foot cable.
Use yellow sheath if possible.
Use twisted pair Ethernet. Never use solid core cable.

The wire colors can vary from the diagram shown above. It is only important that the wires are connected to the correct points.
The A row in the Amp Mod U block (the black rectangular connector) is always on the KEY side of the connector.
Pin 1 is indicated with an arrow embedded in the plastic of the Amp Mod U block.
A wire from A1 to pin 6 is not required for this bender. Some cables will not include that wire.
The wire coming out of B3 indicates if the bender is ON or OFF. Pin B3 outputs between 5 and 10 volts DC when the bender is ON. If the bender control is switched on, the DSR signal at the Benderlink computer's COM port will also be active. The state of the incoming DSR signal can be tested with an RS-232 testing program, like WCom32.exe (You can download WCom32 from our website.)
