4.3 Customising the Input Alert Message
The default input alert message is ‘>INPUTX ACTIVE’. This can be customised by the user using
the CUSTOM command for each input. The maximum length of the message is 127 characters
and it must end with a full stop. The custom command is used as follows:
CUSTOMA THE GATE IS OPEN.
CUSTOMB THE PUMP HAS STOPPED PLEASE CALL 07000000000.
Use only text or number characters in the message. The message will end where there is a full
stop. Do not use a full stop in the middle of the message. If you do not specify channel A or B
the message is applied to channel A.
Separate messages can be specified for when the channel is triggered by a positive going
(logic HIGH) edge or a negative going edge (LOW). This is achieved by adding the appropri-
ate suffix to the command (this is particularly useful when INLEVEL is set to BOTH:
CUSTOMAH this is sent when input A goes positive.
CUSTOMBL this is sent when input B goes negative.
4.4 Autodial Logic
By default, if both inputs are set to autodial, then if either input is triggered dialling will com-
mence (OR configuration). If desired the system can be set to require both inputs to be in the
active state in order to initiate dialling (AND configuration). Additionally the system can be set
for input A to be triggered before input B (A THEN B) in order to initiate dialling. To change the
autodial logic settings the following message is sent to the board:
autodial AND requires both inputs to be active to initiate dialling
autodial OR triggering either input initiates dialling
AUTODIAL THEN A THEN B triggering
aut A
aut o
Aut T
4.5 Changing the Maximum Ring Time
The maximum time for which the system will attempt dialling before dialling the next number is
set using the RTIME command. The default time limit is 60s. The RTIME command is specified in
seconds and can be set from 1s to 255s. Most calls will require at least 15s for connection which
is included in RTIME.
RTIME 45. sets the maximum ring time to 45 seconds
4.6 Changing the Maximum Call Time
The maximum time limit for an answered call is set using the CTIME command. The default time
limit is 45s. The CTIME command is specified in seconds and can be set from 1s to 255s.
CTIME 45. sets the maximum call time to 45 seconds
4.7 Changing the Maximum Line Silence Time
The maximum time for which a silent call will remain connected is set using the SILENCE com-
mand. This is useful were a call may be redirected to voicemail. The silence during recording
will cause the system to hang the call. The default silence time is 15s and can be set from 1s to
255s.
