5.5. Port Configuration
5.5.1. Configuration Conventions
When responding to prompts, invoking commands, and selecting items from the port
configuration menus, note the following:
·
To select an item from a Port Configuration menu, key in the number for the item and press
[Enter].
·
To clear an item in a Port Configuration menu, enter the number for the desired item and
press [Enter]. When the prompt appears, press [Space] and then press [Enter].
·
When defining the Port Name, do not use the forward slash character (/), double quotes
("), the asterisk character (*), or blank spaces.
·
Port Names cannot begin with a number.
·
Refer to the instructions in each screen for additional functions available under that screen.
·
To exit a menu or prompt without changing its current value, press [Esc].
·
Passwords and port names are case sensitive. When defining passwords and port names,
note the exact text, including the case of each character.
·
If you are configuring the APS unit via modem, communication parameters will not be
changed until after you exit from command mode and disconnect from the APS unit.
5.5.2. Port Modes
The APS 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 Mode, Passive Mode, Buffer Mode, or Modem
Mode Ports by accessing Command Mode and invoking the /C command (see
Section 7.1.1). The Any-to-Any Mode is available to all ports.
·
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 7.1.1). The Passive Mode is not available to Ports 1 or 2.
·
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 (/C) Command. Note that the Buffer Mode
also allows pass-through communication with the connected device. The Buffer Mode is
not available to Ports 1 or 2.
·
Modem Mode: Allows communication between connected ports and simplifies connection
to an external modem. A port configured for the Modem Mode can perform all functions
normally available in Any-to-Any Mode. The Modem Mode also allows definition of a
Hang-Up String, Reset String, and Initialization String. Any APS RS232 port can be
configured for the Modem Mode.
For more information on Port Modes, please refer to Section 7.
