用途
    光隔PC機/單片機RS-232電平轉換器（型號：GH232）都用于實現PC機的RS-232電平(±12V）與單片機RS-232電平（0-5V的TTL電平）之間的相互轉換。GH232需要外接5V電源，GH232還可以實現PC機與單片機之間的光電隔離。

    二、性能
    GH232A只用到RS-232的RXD（收）、TXD（發）、GND（地）三根線，支持zui高通信速率9600bps，實際達28800bps以上，隔離電壓2500V。
    GH232外接電源要求5V±0.5V，電源電流小于50mA，建議選用波士電子的微型開關穩壓電源。GH232的5V外接電源可以取自單片機，但是不要取自PC機。

    三、外形圖及使用方法
    GH232的外形都為DB-9/DB-9轉接盒大小。DB-9孔端可以直接外插PC機的RS-232口。DB-9針端有接線端子直接接單片機的串行口。

特點：
    ◆ DMX900 系列可以使 1 臺主控設備與多臺終端設備之間進行數據通信。分為 1 對7 （DMX908）和 1 對 15 （DMX916）兩種型號。
    ◆ 可以通過命令（ASCII 字符串）進行通道切換等操作。
    ◆ 各通道均具有獨立的輸入輸出緩沖區，沒有建立連接時，終端設備發送的數據保存在緩沖區中。 主通道可與具有不同的通信條件的通道通信并且保持輸入輸出的同步。
    ◆ 各通道內置光電耦合器件，具備良好的隔離性能，有效的防止了線路噪聲造成 PC、設備的損壞。
    ◆ 各通道的通信條件可以分別設定，主控設備可以與各種不同通信條件的終端設備通信。
    ◆ 除控制通道切換的命令以外還有大量的控制DMX900的命令，減輕了編寫主機應用軟件的負擔。
    ◆ 本公司的 USB/RS232C 變換器 [DL-U232C]( 另售 ) 可以直接連接到本產品上，這樣，具有 USB 接口的機器也可以通過 DL-U232C 連接到本產品上。
PVIS支持下列Pilz公司的控制系統：PNOZmulti安全系統、PSS可編程控制系統、模件化的控制平臺PSSuniversal和安全總線系統SafetyBUS p。
    這種診斷系統的組態非常容易，因此PVIS也可以為用戶節省工程組態方面的時間和費用。
對于PSS可編程控制系統、安全總線系統SafetyBUS p和模件化的控制平臺PSSuniversal而言，組態工作是通過PSS WIN-PRO軟件來進行的；PNOZmulti使用PNOZmulti編程器進行組態。      
    *的系統信息加上故障的文字信息和系統建議的解決方案都會被顯示出來。所有的顯示信息中包含著6種診斷語言，因此任何的修改都能很輕松的完成。PVIS還為用戶提供了選擇項來生成針對特殊應用的診斷信息。管理人員也可以把他們自己的專業知識加入到系統中以便幫助操作人員消除故障。
    PVIS系統能夠評估控制系統目前的狀態，而且還能在發生故障的情況下識別造成故障的*事件、顯示純文本的提示信息和建議的解決方案。“直到機械設備恢復生產為止，我們預期可以節省zui多50％的時間"，Pilz公司的產品 Jochen Streib說。
