E4418B功率计远程测量没有进入RMT模式

我试图在远程操作模式（RS232 / RS422接口）中配置E4418B功率计。
我发送了几个命令，这些命令在E4418B的hte编程指南中给出。
遗憾的是配置没有完成。
例如，我手动配置了RS232端口的功率计，并发送命令“SYST：REM”，用于将功率计切换到远程操作模式。
每当我发送SYST：REM时，功率计显示屏显示“RX”一段时间而没有进入RMT模式。
如果任何人建议将功率计转换为RMT模式，我会很高兴。
我需要配置远程模式，需要通过RS232 / RS422读取功率电平。
提前致谢！

  I tried to configure E4418B power meter in remote operation mode (RS232/RS422 interface). I sent few couple of commands which are given in hte programming guide of  E4418B.

unfortunately the configuration not getting done. For example I have manually configured power meter for RS232 port and sent command "SYST:REM" for switching power meter into Remote operations mode. Whenever I sent SYST:REM, power meter display indicated "RX" for a while and not getting in to RMT mode.  
I would be nice if any one suggest any idea for turning power meter into RMT mode. Just all I need to configure remote mode and need to read the power levels through RS232/RS422.

Thanks in advance!
