10)	Memory card loading			Connector used to load the memory card to the CPU module.
	connector
				Connector for connection with USB-compatible peripheral device. (Connector type B)
11) USB connector 1				Can be connected by USB-dedicated cable.
				Not available for Q02CPU.
12) RS-232 connector			1	Connector for RS-232 connection
				Can be connected by RS-232 connection cable (QC30R2).
				Used to set the items for operation of the CPU module.
				For system protection and parameter-valid drive functions, refer to the High
				Performance model QCPU (Q mode) User's Manual (Function Explanation, Program
	DIP switches			Fundamentals).
				SW1 : Used to set system protection. Batch-inhibits write and control directives to the
				CPU module. (Shipped in OFF position)
		ON SW
				OFF : No protection

1ON : Protection

13)		2	SW2, SW3: Used to specify parameter-valid drive.
						(Both SW2 and SW3 are shipped in OFF position)
		3		SW2			SW3	Parameter Drive
		4		OFF			OFF	Program memory (Drive 0)
					ON		OFF	SRAM card (Drive 1)
		5		OFF			ON	Flash card/ATA card (Drive 2)
					ON		ON	Standard ROM (Drive 4)
			Note: Parameters cannot be stored in standard RAM (Drive 3).
			SW4 : Must not be used. Normally OFF. (Shipped in OFF position)
			SW5 : Must not be used. Normally OFF. (Shipped in OFF position)
14)	RUN/STOP switch		RUN		: Executes sequence program operation.
			STOP		: Stops sequence program operation.
			RESET : Used to perform hardware reset, operation fault rest, operation initialization,
					etc.
					If this switch is left in the RESET position, the whole system will be reset and
15)	RESET/L.CLR switch				the system will not operate properly.
					After performing reset, always return this switch to the neutral position.
			L.CLR		: Used to turn "OFF" or "zero" all data in the parameter-set latch area.
					Used to clear the sampling trace and status latch registration.
16)	Module fixing screw hole		Hole for the screw used to fix to the base unit. (M3 12 screw)
17)	Module fixing latch		Hook used to fix to the base unit.
			For connection of battery lead wires.
18)	Battery connector pin		(When shipped from the factory, the lead wires are disconnected from the connector to
			prevent the battery from consuming.)
19)	Battery		Backup battery for use of program memory, standard RAM and power failure
			compensation function.

1 : When normally connecting a cable to the USB connector or RS-232 connector, clamp the cable to prevent it from coming off due to the dangling, moving or carelessly pulling of the cable.

Q6HLD-R2 type RS-232 Connector Disconnection Prevention Holder is available as a clamp for RS-232 connector.
