Important: The RC-2A ships by default in the Legacy Programming mode (DIP switch 5 OFF). Optional programming is
also available (see Alternative Programming Mode). The alternative programming mode dramatically changes the pro-
gramming and operation of the RC-2A. Use only the programming features described in the respective sections for the pro-
gramming mode you choose.
The RC-2A contains (3) rotary access/entry code switches (see diagram
right). Using a small flat blade screwdriver, rotate the white arrow on each
switch to the desired access code setting. The code may be any digit 0-9 or
“C” (# on a Touch Tone pad). Note: For extreme security applications, a spe-
cial telephone with a 4 x 4 keypad may be used (Fax Back Document 855).
2. Disabling the Security Access Code
If any rotary entry code switch is set to position “D” the security access code
is disabled. In this case, any call to the RC-2A will have immediate access
to activation codes (see page 5, C. Relay Activation Codes). Note: When
the security access code is disabled, the setting of DIP switch 3 has no effect
(unlimited closures allowed).

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 and 19 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
