3.5.1.7 HSP-2A Keypad – Store Connection Table in Memory
Use the command * 3 6 to store a table of all current module connections in non-volatile
memory. After this has been done, every time power is re-applied to the ACU-1000, these
connections will be automatically restored. Note: the ACU-1000 must not be in programming
mode when this command is used.
The factory default connectivity state is “no connections”, so until the first time the Store
Connection Table command is used, the ACU-1000 will be initialized upon the re-application
of power with no connections made. To change the stored connections, make all the desired
connections, then enter * 3 6. To clear stored connections, terminate all connections, then
enter * 3 6. This command cannot be made via any of the interface modules; it’s valid only
when entered by the HSP-2A keypad.
3.5.1.8 HSP-2A Keypad – Regain Control from Controller Program
The HSP-2A is normally not allowed to enter configuration commands while either the WAIS
or ACU Controller program is remotely controlling the ACU-1000, as the console program can
set configuration much easier. If it is ever necessary to pull back the configuration control
from one of these console programs (for example, if the computer is remotely located and locks
up), enter the command * 3 7 to return control to the HSP-2A.
3.5.1.9 HSP-2A Keypad – Data / Command Modes
The HSP-2A module receives its input audio from the handset, so it does not have a DTMF
detector. Its keypad functions as its DTMF input. If the HSP-2A is in the Command Mode, the
keypad entries are interpreted as commands to the system. If the HSP-2A is in the Data Mode,
keypad entries are not interpreted as commands, but instead the keypad entries are sent as
parallel data to a cross-connected PSTN-2 module. The PSTN-2 regenerates the DTMF and
sends it out on the phone line. The * 8 0 command toggles a module in and out of the Data
Mode. All modules begin operation in the default Command Mode. When Data/Command
Mode command is received, the module switches to the Data mode and returns the prompt
“Data Mode”. Whenever the * 8 0 command is again received, the module responds with the
“Command Mode” prompt and reverts to normal operation.
A simple example of the use of this command assumes the local operator at the ACU-1000
wants to call home and check the messages on his answering machine. The HSP-2A starts out
in the Command Mode. The local operator connects to a PSTN-2 module. Following the voice
prompts provided, he then enters his home telephone number. If he continues to press the HSP-
2A keypad after the call is answered, no DTMF will be transmitted until he enters the * 8 0
command. Once he does, he may enter the password to gain access to his answering machine.
All subsequent keypad entries will result in the transmission of the DTMF characters until he
either toggles out of the Data Mode with another * 8 0 entry or disconnects with a * # entry.
It is important to note that only the PSTN-2 module regenerates DTMF in this way. This mode
was created mainly to allow an ACU-1000 user to make a connection to a PSTN-2 module and
be able to control equipment that is connected to the phone line and uses DTMF signaling
(voice mail systems, answering machines, etc.
