ASCII
ASCII provides connection to other ASCII devices, such as bar code readers,
weigh scales, serial printers, and other intelligent devices. You can use ASCII by
configuring the embedded or any plug-in serial RS232 or RS485 port for the
ASCII driver. Refer to the Connected Components Workbench Online Help for
more information.
To configure the serial port for ASCII, see Configure ASCII on page 47 .
CIP Communications
Pass-thru The Micro820 controllers support pass-thru on any communications port that
supports Common Industrial Protocol (CIP). The maximum number of
supported hops is one. A hop is defined to be an intermediate connection or
communications link between two devices – in Micro800, this is through
EtherNet/IP or CIP Serial.

REMLCD
The user can download a program from the PC to controller1 through the
USB to serial port conversion via the Remote LCD. Also, the program can
be downloaded to controller2 and controller3 over USB to EtherNet/IP but
the performance is limited by the serial connection.
