5.1. Access to the APS-16 Command Mode


When the Command Mode is active, the user can invoke commands to select parameters, display status, and connect or disconnect ports.


•                      The Command Mode can only be accessed from a free Any-to-Any Mode or Modem Mode Port.

•                      The Command Mode cannot be accessed from a Buffer Mode Port, Passive Mode Port, or any port that is currently connected to another APS-16 port.


1                     Start the communications program (e.g. ProComm ). Make certain the APS-16 and ProComm are set for the same parameters (e.g. baud, parity, etc.).

2                     Access the Command Mode.


a) Local Access: To access the command mode from a local PC, type /^E and press [Enter]. If the password feature has been enabled, the APS-16 will prompt the user to enter a password. Key in your password and then press [Enter]. The “APS>” prompt will appear, indicating that the Command Mode is active.

b) Remote Access: To access the command mode via modem,proceed as follows:

i. Dial the number for the external modem connected to Port 1. The unit will send the password prompt.

ii. If you have enabled the password function, key in your password and press [Enter]. If the password function is not enabled, just press [Enter]. The "APS>" prompt will appear.


If the password feature has been disabled, the password prompt will not be displayed.
