A serial port that can use either a DB-9 or DB-25 connector

■
An RS-232 interface cable of appropriate length for your site connection
Depending on how you connect the PC to the control unit, you also need the
following items:
■
Direct local connection, if the PC is within 50 feet of the control unit:
— Either a 355AF modular adapter (if there is a male connector on the
interface cable) or a 355A modular adapter (if there is a female
connector on the interface cable)
— A four-pair modular cord (D8W)
■
Direct local connection, if the PC is more than 50 feet from the control unit:
— 355AF adapter
— EIA crossover cable
— Two Z3A2 Asynchronous Data Units (ADUs)
— ADU crossover cable
— 400B2 power adapter
— 2012D transformer
— BR1A-4P adapter and either a 102 connecting block or 103
connecting block
— 248B adapter
— Eight-position wall jacks
— Four-pair plug-ended cable
— D8W cords
— D6AP power cord
— EIA-232-D cables
■
Modem (local or remote) connection:
— Modem that supports 1200- or 2400-bps connections

In addition, a parallel printer is useful for reports. The PC needs a parallel port for
the connection.
