Olivetti RS232C multiport adapter

The factory settings do not function properly. You must alter the existing switch positions to reflect those listed below.

If you are using a single Olivetti adapter, you must configure it as COM2.

If you are using two Olivetti adapters, one must be configured as COM2 and the other configured as COM1, with the COM1 port built into the M380 disabled. To disable the COM1 port built into the M380, refer to the section on ``Setting Up the System'' in your Olivetti Installation and Operations Guide.

The correct switch settings are:

• As a COM1 (strapped at addr 0x2A0):
  

  IRQ2	IRQ3	IRQ4	IRQ5	IRQ6	IRQ7	XA1	XA0	INT	SHR
  off	off	on	off	off	off	off	on	on	off

  
  

• As a COM2 (strapped at addr 0x1A0):
  

  IRQ2	IRQ3	IRQ4	IRQ5	IRQ6	IRQ7	XA1	XA0	INT	SHR
  off	on	off	off	off	off	off	off	on	off
