S2 DIP Switches
The following sub-sections outline S2 DIP switch functions and settings on door (CA) and elevator (EC) control
boards. Keyscan factory defaults all control board settings prior to shipment. Depending on the installation
however, you may have to reset various switches and reconfigure the control board for specific operating
requirements.
Important
Whenever altering S2 DIP switches, refer to S1 - System Reset / S3 - Restore Factory Defaults on page 57
for determining when you must perform a system reset or restore factory defaults. This ensures the
control board initializes the changes.

S2 DIP Switch Functions
The following sub-headings outline the specific S2 switches and their respective functions.
S2.1 - Communication Mode
Keyscan control boards support serial, network and reverse network communication modes. Reverse network
is a Keyscan proprietary application and requires the purchase of a license.
S2.2 & S2.3 - Communication Bit Rate Selection
The number of bits the control board processes per second. For a communication bus with multiple control
boards, all control boards must be set on the same bit rate. Ensure the control board is set on the desired and
correct rate. Also, ensure that all Keyscan software settings match the control board’s bit rate.
