DIP switches 1-7 may be used to change the operation of the
RC-2A
(see below).
B. DIP Switch Settings
Note:
DIP switches are shown in factory
default settings.
If this DIP switch is in the
ON
position, the relay will not be able to be latched (maintained) and command
codes 10, 19 and 1# will be ignored.
Switch 1: Latch Commands
The ring delay is the number of incoming rings before the
RC-2A
automatically answers the line. The
RC-2A
answers on the fifteenth ring by default. This can be changed to the first, second or sixth ring by following the
instructions above for DIP switch
2
and rotary switch positions.
Switch 2: Ring Delay
If this DIP switch is placed in the
ON
position, only one closure will be allowed during the access.
Switch 3: Closure Limitations
If this DIP switch is in the
OFF
position, the
RC-2A
is in the “Legacy Programming Mode”. In the
ON
position,
the
RC-2A
is in the “Alternative Programming Mode”.
Switch 5: Selecting Modes
With DIP switch 6 in the
OFF
position, acknowledgement tones (beeps for relay confirmation, etc.) are turned
off. With DIP switch 6 in the
ON
position, acknowledgement tones are on.
Switch 6: Relay Acknowledgement Tones
With DIP switch 7 in the
OFF
position, the automatic phone line answering feature is turned off. With DIP
switch 7 in the
ON
position, the automatic phone line answering feature is turned on. See DIP switch 2 and
rotary switch positions for ring delay (total number of incoming rings before the unit automatically answers the
line).
Switch 7: Automatic Answer
This DIP switch is only used in the “Alternative Programming Mode” and has no function in the “Legacy Mode”.
Switch 4: Relay Activation Times
