Ou - Remote Alarm Command:
This command activates the alarms (Relay, Lamp or Horn) on the Cab Control.
This command includes the following information:
Start new command: <ESC>
Command identifier: Ou
Data format to send: xy (x = Alarm Control Code, y = Alarm Oscillation Control Code).
End of command: <EOT>
To turn on an alarm, such as the Lamp, first find the Alarm Control On Code for Lamp (Hex value 0x40)
from the table below. To turn on several alarms, "logically" AND their ON Codes together (Example: When
Lamp's Hex value 0x40 is "logically" AND'ed with Horn's Hex value 0x20, it becomes Hex value 0x60).
Then "logically" AND this value with the desired Alarm Oscillation Code from the table below (example:
Oscillate Alarm Rate 3 Hex value = 0x0C). Next, convert the new hex value “4C" into the ASCII bytes ‘4',
‘C'. This converts it into a two byte ASCII value that can be sent to the Cab Control. To have the Lamp
alarm flash at Oscillate Alarm Rate 3, send "<ESC>Ou4C<EOT>". To have the Lamp alarm stay on
continuously, send "<ESC>Ou46<EOT>". To turn off the Lamp alarm, send "<ESC>Ou06<EOT>".
Data Format for the Remote Alarms:
Alarm Control ON Hex Code OFF Hex Code
Relay 0x80 0x00
Lamp 0x40 0x00
Horn 0x20 0x00
Alarm Oscillation Control Hex Code Hex Code
No Oscillation 0x06 0x06
Oscillate Alarm Rate 1 (Fastest) 0x0A 0x06
Oscillate Alarm Rate 2 0x0B 0x06
Oscillate Alarm Rate 3 0x0C 0x06
Oscillate Alarm Rate 4 0x0D 0x06
Oscillate Alarm Rate 5 ( Slowest) 0x0E 0x06
Remote Alarm Command Response: No response is sent from the Cab Control.
Remote Alarm Command Example:
The following command string
<ESC>OuE6<EOT> would cause all of the Cab Control’s alarms (Relay-
not installed, Lamp and Horn) to activate continuously.
The following command string <ESC>Ou06<EOT> would cause all of the Cab Control’s alarms (Relay-
not installed, Lamp and Horn) to turn off.
