5. Configuration
5.1. Access to the APS Command Mode
When the APS Command Mode is active, commands can be invoked to select parameters, and
connect or disconnect ports.
Note: Command Mode cannot be accessed from a Buffer Mode Port, Passive Mode
Port, or any port that is currently connected to another APS port.
1. Start your communications program (e.g. ProComm
). Make certain the APS and
ProComm are set for the same parameters (e.g. baud rate, parity, etc.).
2. Access the Command Mode.
a) Local Access: To access the command mode from a local PC that is connected to the
APS via cable, press [Enter].
i. There must be no other characters preceding [Enter]. If you have already hit
other keys, press [Enter] twice.
ii. If the Supervisor Password has been defined, the password prompt will be
displayed. Key in your Supervisor or Port password and press [Enter]. The
"APS>" prompt will appear.
b) Modem Access: To access the command mode via modem, proceed as follows:
i. Dial the number for the external modem connected to the APS.
ii. If you have defined the Supervisor Password, a prompt will be displayed. Key in
your Supervisor or Port password and press [Enter]. If the Supervisor Password
has not been defined, just press [Enter]. The "APS>" prompt will appear.
5.2. System SetUp Ports
As discussed previously in Section 3 of this User’s Guide, Ports 1 and 2 are designated as
System SetUp Ports. Ports 1 and 2 will always permit password protected access to Supervisor
Level command functions, even when the unit is initialized to default parameters.
In order to ensure that access to command functions is always available, Ports 1 and 2 cannot
be configured as Buffer Mode or Passive Mode Ports (Buffer and Passive Mode Ports are not
able to access the Command Mode.) In addition, Ports 1 and 2 always permit password
protected access to Supervisor Level commands; the Supervisor Mode cannot be disabled at
these two ports.
5.3. Password Functions
The APS features two different types of passwords; the Supervisor Password and the Port
(User) Passwords. The Supervisor Password allows system administrators to invoke unit
configuration commands, and the Port Passwords allow users to access specific ports in order
to create connections between permitted ports or view port configuration parameters.
