SECTION 2:
CAMERA/MONITOR SELECTION
2.1 MONITOR SELECT
2.1.1 Single Monitor MaxCom Gold Keyboard
The MaxCom Gold displays the video input number that is switched to a monitor on the
top left corner of the monitor display. The Single Monitor MaxCom Gold keyboard has a
dedicated fixed connection to either monitor 1 or monitor 2, depending on the keyboard
port it is connected to. (KBD 1 or KBD2.) Pressing the monitor button will produce an
error beep as the keyboard cannot select a monitor. A right arrow () to the left of the
camera number indicates the monitor is under keyboard control.
2.1.2 Multi Monitor MaxCom Gold Keyboard
The Multi Monitor MaxCom Gold keyboard allows control of either monitor that is
connected to the MaxCom Gold (as long as this has been set up in the menu - see
section 8.3.3). The MaxCom Gold displays the video input number switched to a monitor
on the top left corner of the monitor display. A right arrow () to the left of the camera
number indicates the monitor is being controlled by the keyboard.
To switch the keyboard control to the other monitor in the system, press the monitor
button.
Note: telemetry commands are always sent to the camera that is displayed on the
monitor that is currently being controlled by a keyboard, i.e. showing the next
to the camera title.
2.1.3 RS485 and RS232 Keyboard Control
The MaxCom Gold can be configured so that either an RS485 keyboard or an RS232
keyboard can control one or both monitor outputs. RS485 keyboards are connected to
one of the RJ45 sockets (KBD1 or KBD2) and the RS232 keyboard is connected at the
RS232 CTRL connector.
If an RS232 keyboard has control of a monitor, an asterisk (∗) is displayed to the left of
the camera number on the monitor.
Two keyboards cannot control the same monitor output at the same time. This does not
mean that the operator has to be actively using the keyboard all the time. It just means
the operator can take control of the monitor output at any time. The RS232 keyboard
always has priority over the RS485 keyboard when both keyboards are connected to
the MaxCom Gold and configured to control the same monitor output. If an RS485
keyboard tries to control a monitor output being controlled by an RS232 keyboard, the
message, "RS232 KEYBOARD CONNECTED", is displayed on the monitor being
controlled by the RS232 keyboard (the same monitor the RS485 keyboard is trying to
control), and a long error beep is produced at the keyboard.
