10.3  Inputs and Outputs 
The two digital outputs are potential-free relay switches.  
Maximum switch voltage: 30 V (DC) / 42 V (AC) 
Maximum current load: 1 A (DC) / 0.5 A (AC) 
The digital inputs are designed as pull-up and are on HIGH in inactive, open state. The 
inputs are activated by connecting to ground. 
LOW 0 .. 1 V 
HIGH 4 .. 12 V 
The input current from LOW to internal 3.3 V is typically 0.35 mA. 
10.4  Integrated Switch 
This is a switch, consisting of  
¾
  4 ports 
¾
  10 / 100 MBit/s for full and half duplex operation (Autosense) 
¾
  Automatic detection of patch cables/cross over cables 
 
10.5  Integrated Communication Module 
Depending on the MoRoS variant, the following can be integrated as communication 
module: 
¾
  Analogue modem, or 
¾
  ISDN terminal adapter 
 
The analogue modem achieves a maximum data amount of 56kBit/s for connection to 
ISPs (Internet Service Providers). For connections into other private LANs, a maximum 
data amount of 33.6kBit/s can be achieved. The transmission speed, however, depends 
very strongly on the line quality. It may therefore occur that the theoretically achievable 
maximum transmission speed is slower. 
The integrated communication module of the MoRoS is an i-modul Modem 56k PRO. The 
technical data as well as the entire AT command set are summarized in the "Designers 
Guide wired” and can be requested free of cost at “www.insys-tec.de”. 
An i-modul ISDN-TA+HUT is integrated in the MoRoS ISDN. It achieves a maximum data 
amount of 64 kBit/s. In contrast to the analogue modem, this value is fixed. All technical 
data regarding this topic are again summarized in the “Designers Guide wired” and may 
be obtained from INSYS Microelectronics free of cost.
