A device as shown with a 3m connecting lead which couples directly into the TT motor unit. Control is simply “CW”, STOP and “CCW”. It can be used in place of 2090 controller on an open area site where operator presence in the vicinity of the table is not critical. Note: This device would normally be ordered in place of (Item 824). It mainly sees use in calibrating the table azimuth with reference to the readout on the 2090 controller. If table is delivered pre-calibrated then this will not be needed.
