Titan CPU Channel Mul plexer - Notes
Notes & Known Issues
Addi onal informa on about the CPU not covered elsewhere:
Error Indica ons:
If a Titan Input Device (Mini-Recorder or Pod) stops sending data for any reason, the
CPU will stop recording/stop scanning and display an error (the ERR LED will be ON).
CPU Power Loss/Data Loss:
1. In the event of a power loss while recording remotely to the CPU, data loss is limited
to 10 seconds maximum.
2. If the CPU loses power while scanning, all independently-powered Titan Input
Devices (Mini-Recorders or Pods) must be power-cycled in order to resynchronize the
system.
CPU Remote Recording:
The CPU does not automa cally handle Pod confi gura on changes made since the
last remote recording (for example, if Pods are swapped between ports, or if a Pod is
removed and used for another test, and then reconnected to the CPU). If a change
occurs between tests, connect to TCS and run a short test to reconfi gure the CPU and all
connected Pods prior to resuming remote recording.
Remote Switch Opera on:
If the Remote Switch is connected to the CPU and switched ON, the CPU will a empt
to record repeatedly even if no pods are connected or an error condi on exists. Each
a empt will generate a small data fi le on the CPU. These fi les are invalid.
Mini-Recorder/Pod Reconfi gura on
When a Mini-Recorder or Pod is connected to the CPU, the baud rate on the COMM
port is reset to 3Mbits. Remote recording func onality on Mini-Recorders is also
disabled (this includes both the front panel switch and the REM jack on the Mini-
Recorder). The default baud rate and remote recording capability is restored on Titan
Mini- Recorders a er running a test directly from TCS.
