4.3.3. SNMP Trap Timestamp File
To prevent the resending of traps/informs upon a system restart, a timestamp of the last
trap/inform is stored locally on the unit. The “/home/microlok/snmp.trap.timestamp” file
contains this timestamp. When the software starts, this timestamp is read and used to
prevent any previously generated traps from being sent to the SNMP manager. The
timestamp is updated each time a new trap or inform is sent.

4.4. Invoking the M
ICROLOK II
Development System
The MLK Development System (also referred to as “Dev Tool”) is a software application
used to communicate with installed MLK systems. This manual covers accessing the
“Dev Tool” locally (using a Windows-based computer; typically connected to port ETH0
on the TIM) or remotely (using a network workstation; typically connected to port ETH1
on the TIM). This manual does not cover detailed use of features typically available
within the “Dev Tool.”
4.4.1. Locally at the TransPortal Interlock Monitor
A communication port on the local computer must be configured to interface with
Ethernet port ETH0 (typically) on the TIM. This is done using a serial-to-TCP/IP
converter application (TCP-Com) included in the “Dev Tool” installation package for this
TIM application.
