5.5.3.1. RS232 Port Modes
The CMS-6R4 offers four different port operation modes; Any-to-Any Mode,
Passive Mode, Buffer Mode, and Modem Mode. The Port Modes function as
follows:
• Any-to-Any Mode: Allows communication between connected ports.
Any-to-Any Mode Ports can be connected to other Any-to-Any, Passive,
Buffer, or Modem Mode Ports by accessing command mode and invoking
the /C command (see Section 6.2.3). The Any-to-Any Mode is available
to all CMS-6R4 ports, except the Internal Modem Port.
• Passive Mode: Allows communication between connected ports, but
does not allow access to command mode. Passive Mode Ports can be
connected by accessing command mode from a free Any-to-Any or
Modem Mode port and invoking the /C command (see Section 6.2.3).
The Passive Mode is not available to Ports 1 and 2, or the Internal
Modem Port.
• Buffer Mode: Allows collection and storage of data received from
connected devices. Collected data can be retrieved by accessing
command mode from a free Any-to-Any or Modem Mode Port, and
issuing the Connect Command (/C.) Note that the Buffer Mode also
allows pass-through communication with the connected device. The
Buffer Mode is not available to Ports 1 and 2, or the Internal Modem Port.
• Modem Mode: A Modem Mode port can perform all functions normally
available in Any-to-Any Mode, but the Modem Mode also allows
definition of a Hang-Up String, Reset String, and Initialization String.
Any CMS-6R4 RS232 port can be configured for Modem Mode, and the
Internal Modem port is always configured for Modem Mode.
