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.
Example:
A access control attempt is made using a button or card. The ID of the button/card is:
039-30391
The corresponding message is:
$PGPS,171134.00,A,4915.3868,N,12259.8049,W,000.0,000.0,00004,5,09604890958,
039-30391,V*33
where “V” indicates the ID is a valid ID as compared against an internal list stored on the CTM-200. “F” would
indicate an invalid ID.

areas where radio emissions are prohibited (blasting areas). The accessory has a super bright LED indicating
