Page 52: Rs232 Interface
RS232 interface The achievable distance between two RS232 devices depends on the cable used and the baud rate. As a guideline measurement, for a transmission rate of 9600 baud the distance should not exceed 15m to 30m. The permissible ohmic load must be larger than 3 kOhm and the capacitive load caused by the transmission cable must be smaller than 2500 With the PC cable for the RS232 interface (2m)

Profibus DP The UMG96S has a 9-pin SubD socket in the Device master file rear panel. A RS485 interface with which the The device master file for the UMG96S is called profibus DP protocol is operated is wired to the „U96S0781.GSD“.
Page 55 Cable length The maximum permissible cable length depends on the type of cable and the transmission rate level. The length of the cable is measured between the bus driver of the first device and the bus driver of the last device. We recommend you only use shielded cables which conform to the standard EN50170-2 cable type A.
