External communication
Communication with the host processor takes place in RS232 serial communication channels
which are available in both the CPU bus and the module bus. Two signals, TXD and RXD, are in use.
No handshaking is used. The 26-pin subminiature D-connector of the Command Board/Bar is
connected to a Display controller board. Serial communication speed rate is 19.2 kbps.
ComWheel
The ComWheel on the front panel is used for menu selection.

LEDs
The alarm LEDs are activated by the Command Board/Bar PCB under the commands received via
serial communication from the CPU board. The red or yellow alarm LED is lit when red or yellow
alarm is activated. STBY -led is lit when the device is turned to stand-by and connected to mains.
NOTE: If there are two Command Boards/Bars connected to the system, the system is ON (STBY
LED not lit), when at least one of the switches is positioned ON.

2.2 Remote Controller, K-REMCO
The Remote Controller consists of 12 direct function keys and the ComWheel.
K-REMCO PCBs
The K-REMCO has two PCBs located inside the Remote Controller. One board has only the
pushbutton switches of the keys. The other board reads the status of the keys and the ComWheel
and forwards the information to the CPU board.
External communication
K-REMCO with standard cable:
Communication with the host processor takes place in RS232 serial communication channels
which are available in both the CPU bus and the module bus. Two signals, TXD and RXD, are in use.
No handshaking is used. The 26-pin subminiature D-connector of the Remote Controller is
connected to a Display controller board. Serial communication speed is 19.2 kbps.
K-REMCO with optional Remote Controller - Compact Monitor cable:
The Compact Monitor or LCD display, D-LCC10A/W converts the communication to RS232 format
(see above).
ComWheel
The ComWheel is used for menu selection.
