當主通信中斷時(shí)，%I參考（位0）和DCS LED立即復位恢復在Modbus讀取異常之前，異常狀態(tài)字節中的位保持設置收到命令。
如果HE693RTU940與手機配合使用，則應設置波特率至300，以避免噪聲導致數據損壞，需要根據信息調整DCS大小將DCS配置為5或更多的設置應消除任何數據錯誤。3.6前面板診斷LED
當RS-232端口的相關(guān)線(xiàn)路上有活動(dòng)時(shí)，RXA、TXA將閃爍。如果RS-485端口
HIMA F8652E控制模塊當該端口的相關(guān)線(xiàn)路上有活動(dòng)時(shí)，RXB、TXB將閃爍。如果調制解調器端口被選中時(shí)，RXA將閃爍表示摘機活動(dòng)，TXA將閃爍表示來(lái)電。
如果DCS未超時(shí)或未啟用，當有效的ModbusRTU接口模塊已接收并正在處理消息。如果接收燈為如果DCS不閃爍，這通常表明幀協(xié)議不正確。如果DCS是啟用并超時(shí)后，該LED以恒定1秒的速率閃爍。3.7撥號%R（僅限HE693RTU940）撥號%R參數是指定用于存儲用戶(hù)希望撥打的電話(huà)號碼（撥號字符串）。此設置因使用的寄存器數量而異根據表盤(pán)串的長(cháng)度。用于撥號%R參數的寄存器不得
The %I reference (Bit 0) and the DCS LED are reset immediately when master communications is
restored. The bit in the Exception status byte remains set until after the Modbus Read Exception
command is received.
In instances where the HE693RTU940 is used in conjunction cellular phones, the baud rate should be set
to 300 to avoid data corruption due to noise and the DCS will need to be adjusted according to message
size. Configuring the DCS to a setting of 5 or more should eliminate any data errors.

Front Panel Diagnostic LED’s
RXA, TXA will flicker when there is activity on the associated lines for the RS-232 port. If the RS-485 port
is active, RXB, TXB will flicker when there is activity on the associated lines for that port. If the modem
port is selected, RXA will flicker indicating off-hook activity and TXA will flicker indicating an incoming call.
If DCS has not timed out or is not enabled, the DCS LED will momentarily light when a valid Modbus
message has been received and is being processed by the RTU Interface Module. If the RX light is
flashing and the DCS is not, this generally indicates that the frame protocol is incorrect. If DCS is
enabled and timed out, this LED flashes at a constant 1 Second rate.

Dial %R (HE693RTU940 only)
The Dial %R parameter is the reference address that specifies the registers that are used to store the
phone number (dial string) the user wishes to dial. This setting varies in the number of registers used
according to the length of the dial string. The registers used for the Dial %R parameter must not
