As a policy of continual improvement, RMF reserves the right to alter the specification without prior notice.

9.1 RDU 2.0 

 
 
The optional CMSRDU2 is a separate accessory product allowing control of a CMS that is typically inaccessible via 
the keypad, display and USB download.  
 
The sensor itself is mounted remotely in another unit (normally a non-screened version). This allows the operator 
full control of the CMS. 
 
The CMS

RDU2 connects "in between’’ the incoming supply/serial connections, and the 

CMS sensor. It is 

"tra

nsparent’’ to the serial communications. This means that a PLC or 

RMF-View can operate in the usual way to 

control the CMS, change settings or download results, without having to unplug the RDU. 
 
Similar components are used for the RDU as for the normal CMS-KU option, so the same instructions apply for 
operation. See chapter 6.2.2.2 for more details. 
 
The RDU wiring details are shown in figure 6.4. 
 
Please note that the RDU cable provided must be plugged into the 

right hand

 (remote) connector of the CMS for 

it to work. 
 
Please note that the RDU only records tests whilst powered up. If tests are run without the RDU connected then 
they will have to be downloaded directly from the CMS. 
 
If the CMS connected to the RDU has a serial number lower than 1610800, then the power supply must go via the 
RDU. Serial numbers after 161800 can be powered either via the CMS or RDU. 
 
The CMSRDU2 is fully backward compatible with the first revision CMS products. 

 

9.2 CMSUSBI 

 
The USBi is a plug and play solution for easily connecting a computer to the CMS. 
 
It includes a USB: RS485 interface with a terminal block pre-wired with the CMS cable. An extra terminal block is 
provided for any customer wiring to external devices.  
 
An external DC adapter supplied can be used to power the complete system, or if the computer is always 
connected during use, power can be taken directly from the USB cable.  
Note: Computer should have mains power applied at all times. 
 
Detailed installation and usage instructions are provided in the separate product user guide.
