AC codes are Code 1 through Code 28 The test unit will ignore code selections as the switch is being turned unless there is a long enough pause on an intermediary selection e Code T toggles transmission of the trouble code This switch is only effective if Code T mode is enabled via the serial interface see section Code T below If enabled when this switch is turned on Code T will be transmitted using the location ID and trouble code as set via the serial interface When the switch is then turned off the test unit will complete the active Code T transmission and then stop So to send only one Code T flip the switch on and then off again e Code 5 6 this switch is a three position switch that toggles transmission of Code 5 or Code 6 As these codes are mutually exclusive both can not be transmitted simultaneously Per the Genrakode specification when Code 6 is selected only one Code 6 pulse will be sent followed by Code 1 The current Code 5 setting will be held over for about one cycle when the switch is flipped to Code 6 so a quick flip to Code 6 and then back to Code 5 will ensure that one Code 6 pulse is sent without disturbing the Code 5 transmission e Transmit Enable as its name implies this switch enables transmissions from the test unit Because this switch is interfaced directly to the analog transmitter circuitry within the unit the transmit LED will continue to blink when the unit would normally transmit However
