Note

1. The NT-AL001-E must be supplied externally with 5 V DC. When an NT-

AL001-E is connected to a CPM2B PC, pin 6 of the CPM2B’s RS-232C port
supplies +5 V DC and an external power supply is not necessary. When the
NT-AL001-E is connected to a host computer, it is necessary to supply 5 V
DC from an external power supply.

If an NT-AL001-E is connected to the CPM2B’s RS-232C port, only one Ex-
pansion I/O Board can be connected to the CPU Board because the NT-
AL001-E draws its 5-V DC power from the CPU Board.

Use an XW2Z-070T-1 (0.7 m) or XW2Z-200T-1 (2 m) cable to connect the
NT-AL001-E to the CPM2B’s RS-232C port.

2. The 3G2A9-AL004-E requires an external AC power supply (110 V AC or

220 V AC).

3. The CPM1-CIF11 is supplied +5 V DC from the peripheral port so an exter-

nal power supply is not necessary.
