IDM T6
The IDM T6 DAU is an IDM T3 DAU enclosed in a carrying
case for portable use.
Access to the 16 analog and 32 event channels is via 4mm
safety connectors accessible at the rear of the case.
All IDM DAU types are equipped with fully internal signal
conditioning making them very compact units and suitable for
mounting in the relay panel of the feeder or item of equipment
being monitored. They can be equipped with an optional
internal GPS decoder or synchronized by an external time
source (e.g. IRIG B).
The DAU Channel Configuration Sheet provided with each
recorder gives full details of the analog and event channel
configuration and the supply voltage for each recorder. Sample
forms for each recorder type are included in Appendix A.

following functions in an IDM installation:
# Non-volatile storage for DFR, TSS and CSS records
# Modem sharing between multiple DAUs
# Printing records from multiple DAUs
The LSU is equipped with two serial ports, an internal 56K
modem, a minimum 20Gbyte hard drive and a network interface
card equipped with a 10 base T and AUI port. It runs the
