1-3-1		Serial Communications Board

	Device name			Serial Communications Board

	Model number			CQM1H-SCB41

	Classification			CQM1H-series Inner Board

	Supporting CPU Units			CQM1H-CPU51/61

	Number of mountable Boards/PC and			One Board per PC maximum, must be in Inner Board slot 1
	mounting location
	Serial communications		Port 1	RS-232C
	ports
			Port 2	RS-422A/485


	Protocols		Port 1	Host Link, protocol macro, no-protocol, 1:1 Data Link, 1:N-mode NT Link
				or 1:1-mode NT Link can be selected for each port.
			Port 2


	Software interface with CPU Unit			IR 200 to IR 207 (words for Inner Board slot 1)

	PC Setup settings			DM 6550 to DM 6559 (in read-only DM area in CPU Unit)
				Set from Programming Device

	Current consumption (see note)			200 mA max. at 5 V DC

	Dimensions			25 ⋅ 110 ⋅ 107 (mm) (W ⋅ H ⋅ D)

	Weight			90 g max.

	Standard accessories			Socket: XM2SA-0901 (OMRON) (two included)
				Hood: XM2SA-0911-E (OMRON) (two included, ESD compatible)

Note The current consumption is for one Serial Communications Board. Power is sup- plied from the CQM1H

When an NT-AL001-E Link Adapter is connected to the Serial Communications Board, power is supplied to the Link Adapter from the Board. A current consump- tion of 150 mA must be added for each Link Adapter that is connected. In the above specifications, “x” indicates that 150 mA must be added for each port to which an NT-AL001-E Link Adapter is connected to provide the required 5-V power supply.

1-3-2 General Specifications

Conform to SYSMAC CQM1H-series CPU Unit specifications.

1-4 Basic Operating Procedure

An overview of the basic operating procedure is provided here. Details are pro- vided in sections 4 to 8 of this manual according to the serial communications mode.

1, 2, 3... 1. Turn OFF the power supply to the PC.

2.Mount the Board.

3.Connect the Board and the external device(s).

4.Turn ON the power supply to the PC.

5.Set the PC Setup settings from a Programming Device (e.g., Programming Console or CX-Protocol).

6.Execute communications.

Use the control bits, flags, and words allocated in the IR area in the ladder program to control communications.
