 Telescope is a Planewave PW1000. It is controlled through the pwi1m computer in the 1m dome, running Windows. pwi1m has two network interfaces. One connects to the telescope internal network on 192.168.10.XXX. pwi1m is 192.168.10.40, the Maestro controller on the telescope is 192.168.10.50, and the OTA controller on the telescope is 192.168.10.60.
-Software control is through Planewave's PWI4 software. This runs  under Windows on pwi1m , and provides a graphical user interface, as well as an ASCOM driver and also a custom Planewave HTTP API.

 Normal telescope control is done remotely through the ASCOM interface, but interacting with PWI4 directly provide additional functionality. In particular, PWI4 incorporates its own pointing model software.

 The dome has motorized upper and lower slit sections. Control of the upper slit and dome rotation is done through a custom relay box on the S side of the dome constructed by the Autoscope Corporation; the lower slit is controlled through a box on the N side, designed and constructed by Dave Woods. There is a manual/automatic toggle to allow dome control either through switches on the side of the boxes, or via remote control. Relays to control the dome motors are 24V relays and are activated by setting input control lines to ground. The 24V power is supplied externally. A watchdog is implemented in automatic mode such that +24V needs to be supplied or else dome shutter will automatically close.
-There is an encoder coupled to the dome motor drive shaft.
+There is an encoder (BEI Motion Systems Optical Encoder E206-1000-3G) coupled to the dome motor drive shaft.
 There is a magnetic home sensor installed on the E side of the dome; the home position when the magnet on the dome lines up with the sensor places the slit at an azimuth of 80 degrees.
