 ====== What's New at VATT ======
+----
+===== Guide Box Y Axis as of December 2022 =====
+A new type of error has started showing its ugly head in mid-November. It usually starts with the Y axis of the
+guider camera's 3-axis translation stage. For example, the command is to move from 0 to +65. Motion stops at +35.
+**Solution.** Cycle power on the MOXA serial-to-ethernet media converter: In the Dome, pull the power-over-ethernet cable (orange) out of the Moxa unit and plug it back in. In Control room, run ''Initialize'' and ''Reference'' from the user Secondary-and-Guider GUI.

 You may use a new ''Watchman'' wifi device for independent measurements of temperature and humidity in the dome. It is plugged in (it needs 5V power) by the flood lamp and the dome cameras (legacy and HikVision). This is "dirty" power, which means that the device is available during lightning shutdowns.

 These monitors are nice.

 The AOC 4k monitors are U4308V.  {{ :vatt:aoc_product_manual_u4308v_english.pdf |Here is the manual.}}
+Note that the ''Input Select'' in the monitor's main menu must be set to ''Auto'' (see p. 21 of the manual). When this is the case, the monitor reliably finds the source (HP Thin Client or a laptop attached to the ''HDMI 2'' port). :!: Make sure that the ''Input Select'' is set to ''Auto'' :!:
+Also note that the multipurpose button can be used (pushing it upwards) to activate a simple source selection menu (see p. 12 of the manual). When you do use the simple source selection menu to select a source, however, go back to the main menu and make sure that the ''Input Select'' is set to ''Auto'' because selecting a source with the small menu changes the settings in the main menu.
+Note that there is a power switch at the bottom of the monitor next to the socket for the power cord.
