5.8 Low Power/Standby Mode
The DPX-213 has a low power feature that allows the unit to be placed in a state where it
will draw no current.
There are 2 methods of entering this state, namely:
•
Using the ATZ1 command, or,
•
Placing a value other than 0 in the inactivity timer registers S36/37, and allowing the
unit to sit in offline Idle Mode until the inactivity timeout is reached.
To enter standby mode in both instances, the DTR must be disabled or held inactive. The
modem will wake up on rise of DTR (if DTR is enabled), ring detection, activity on the
DTE TxD input, or power cycle.
5.9 Alarm Mode
Alternate number dialling. In alarm mode, when an alarm call is made, the unit will dial
the number in location 0. If the call is unsuccessful the unit will attempt to dial the number
contained in location 1. If this does not exist, the modem will revert to location 0. For
every attempt (or pair of attempts if location 1 contains a number) the modem checks if the
redial count (S50) has been reached and gives up if this occurs.
Alarm detection while on line. If the DTR is raised while on line or during disconnection
the modem will detect the raised DTR and generate another alarm.
5.10 Password Mode
On answering a call the unit will respond with a password prompt (location 9 string) or
PASSWORD ? if location 9 is not programmed. The modem will then wait for 20 seconds
and allow 3 attempts to enter a correct password. Is a correct password is seen the unit
will connect (AT*P1) or disconnect and attempt to dial-back the user. If the unit is in dial
back mode and a correct password is entered which does not have a dial back number, the
caller will not gain access even though the modem indicates a correct password entry.
Storage locations 5-8 may be used for password storage.
Passwords are stored in the following format. For example:
\password,password\number
\fred\t2225555\jim\\sid\t5554444
\ian,sigmund,kylie\t4365879\terry\
