4 Configuration and Activation
This section details how to quickly get an TTU-12x0™ provisioned and configured to point at a specific server. It is assumed that a
PEG script has already been created and is being managed through LMU Manager or PULS™, the CalAmp Maintenance System.
We are making three assumptions to simplify the setup process:
You have created, installed and configured an LM Direct™ Server to receive messages from the TTU-12x0™. (See
LM Direct™ Reference Guide for details)
You are using the standard wiring harness from CalAmp and the serial port expansion harness.
You have created a HyperTerminal or Putty session.
You have contacted the CalAmp sales team regarding the network availability of the TTU-12x0™. This
device may not be supported for all the carriers or networks listed in this section (CDMA-Verizon, CDMA-Sprint,
HSPA, GSM), for product availability consult the CalAmp sales team.
