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)

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.
