The J-202-XPR series controller accepts
only one (1) option card, where ports for
the NPB-2X-485 are COM7 and COM8.
For other JACE models (JACE-200/600,
SEC-J-x01) up to 2 RS-485 option cards
may be installed, where:
•If single RS-485 option in Option Slot 1,
ports are COM3, COM4.
•If two RS-485 options, ports are
COM3, COM4 for Option Slot 1,
and COM5, COM6 for Option Slot 2.
•If single RS-485 option in Option Slot 2,
ports are COM3, COM4, unless one of
the following are in Option Slot 1:
• NPB-232: ports are COM4, COM5.
• NPB-GPRS: ports are COM5, COM6.
