COM2（RS-485，15针凹形D-sub连接器）–RX7i CPU/CRU型号此端口不提供+5Vdc电压，因此RS-485到RS-232转换需要一个自供电的转换器。它不支持RS-485到RS-232适配器IC690ACC901。这是一个DCE端口，允许简单的直通电缆与标准AT型RS-232端口连接。要使用内置120Ω电阻器提供终端，请在引脚9和10之间安装跳线。76为了使用外部电阻器提供端接，在引脚10和11COM2之间连接用户提供的电阻器（RS-485，15引脚母D-sub连接器）–所有RX3i CPU/CRU型号和RX3i CPE310这是一个DCE端口，允许简单的直通电缆与标准AT型RS-232端口连接。屏蔽电缆屏蔽从模块正面看位于连接器的右下方。2 NC无连接3 NC无连接4 NC无连接5+5Vdc逻辑电源：为外部选项提供隔离的+5Vdc电源（300mA）。6 RTS（A）差分请求发送A 7 0V信号接地8 CTS（B’）差分清除发送B

COM2 (RS-485, 15-pin Female D-sub Connector) –RX7i CPU/CRU Models This port does not supply +5Vdc volts, therefore RS-485 to RS-232 conversion requires a converter that is self-powered. It does not support the RS-485 to RS-232 adapter IC690ACC901. This is a DCE port that allows a simple straight-through cable to connect with a standard AT-style RS-232 port To provide termination using the built-in 120Ω resistor, install a jumper between pins 9 and 10. 76 To provide termination using an external resistor, connect a user-supplied resistor across pins 10 and 11.COM2 (RS-485, 15-pin Female D-sub Connector) – All RX3i CPU/CRU Models & RX3i CPE310 This is a DCE port that allows a simple straight-through cable to connect with a standard AT-style RS-232 port.Shield Cable Shield Located at the bottom right of the connector as viewed from the front of the module. 2 NC No Connection 3 NC No Connection 4 NC No Connection 5 +5Vdc Logic Power: Provides isolated +5Vdc power (300mA maximum) for powering external options. 6 RTS(A) Differential Request to Send A 7 0V Signal Ground 8 CTS(B‘) Differential Clear To Send B
