前面板说明
Front panel description
档位：该传令钟共分为十一个档位，即进一、进二、进三、进四、停车、完车、
备车、退一、退二、退三、退四。
通信：采用串行数据传输技术，使发送器（驾驶室传令钟）到接收器（机舱回令
钟）的传输信号不被外界环境干扰。
显示：能同时显示双方（传令钟和回令钟）的工作状态，当传令钟向回令钟发送
信号时，对应的指示灯为闪亮同时伴有声音报警，直到机舱回令钟回复驾
驶室传令钟时，指示灯变为常亮状态同时声音报警消失，机舱传令钟再次
回复信号后指示灯信号消失，恢复初始状态。同理：当机舱回令钟向驾驶
室传令钟发送信号时，重复上述过程。
失电报警：当主电源（
AC24V
）失电时，自动转到
DC24V
，同时对应的
LED
闪
亮报警，主电源恢复正常后自动撤销报警。
误车报警：当机舱传令钟或驾驶室回令钟操作失误时，对应的红色
LED
闪亮，
警告主机操作失误。
紧急按钮：当驾驶室传令钟或机舱回令钟出现故障时，双方可以使用面板上的紧
急按钮传递信号。
调光：按自己需要可调节指示灯亮到适当亮度。
消音：出现报警时，可以按此按钮消除报警声。
VDR
接口：符合
NMA0183
标准，该接口可接车钟记录仪。
Gears
: The engine order telegraph is divided into 11 gears, i.e., ahead full,
ahead half, ahead slow, ahead dead slow, standby, stop, fwe, astern dead slow,
astern slow, astern half and astern full.
Communication
: It adopts serial data transmission technology, which makes
the transmission signal from the transmitter(engine order telegraph in the
operator cab) to the receiver(engine reply telegraph in the passenger’s cab)
undisturbed by external environment.
Displaying
: It can simultaneously display the working state of both the engine
order telegraph and engine reply telegraph. When the engine order telegraph
sends signal to the engine reply telegraph, the corresponding indicating light
flashes with audible alarm. When the engine reply telegraph in the
passenger’s compartment replies to the engine order telegraph in the
operator’s cab, the indicating light turns to be normally on and the audible
alarm disappear. When the engine reply telegraph in the passenger’s
compartment replies to the signal again, the signal of indicating light disappear
and return to original state. In the same way, when the engine reply telegraph
in the passenger’s compartment sends signal to the engine order telegraph in
the operator’s cab, repeat the above process.
No-power alarm
: When the main power supply(AC24V)has no power, it will
automatically turn to DC24V, and meanwhile the corresponding LED flashes
for alarm. When the main power supply returns to normal, the alarm will
