Access Control
The CTM-200 supports the I-Button® and HID® proximity card systems for access control. The access
control devices can be connected via serial or GPIO connector on the CTM-200. The CTM-200 supports
both wiegand and serial protocols. The CTM-200 can be configured to execute “scripts” on lock and unlock.
For example, an unlock script may trigger an output to control a relay that enables vehicle ignition. The
CTM-200 can also store an “Access control list” which is a list of ID’s that are “valid” . When an access
control request is made, the ID from the button or card is compared against a stored list on the CTM-200. If
the ID is valid an unlock script would execute, unlocking a door, or enabling ignition. When an attempt is
made at access control the CTM-200 generates a report message containing the ID of the button or card
and whether the card is a valid or invalid card based on the stored list on the CTM-200. The ID payload is
appended to the end of the $PGPS message, message 114. The message is automatically generated when
an access control attempt is performed.
