Modem/ISDN port
The MC5-IP models provide a serial 
port to allow you to connect either 
a modem or ISDN terminal adapter. 
This can be used as a primary, 
secondary or backup access port 
for global users, as best suits your 
overall configuration.
IMPORTANT: When the MC5-IP is 
accessible from the public Internet or 
dial up connection, you must ensure 
that sufficient 
are employed.
Note: On non-IP models, the 
COM2/MODEM port is reserved for 
the support of future features.
To connect a modem or ISDN adapter
1  If possible, disconnect power from the MC5-IP and the modem or ISDN 
adapter.
2  Connect a suitable serial modem (non-crossover) cable to the serial port on 
the modem/ISDN adapter.
3  Connect the other end of the serial cable to the port labelled COM1 at the 
rear of the MC5-IP.
Note: The default serial port speed is 115200 and a standard Hayes-compatible 
auto-answer string is sent during startup. The default startup string is 
‘ATZHS0=1’. Both the serial port speed and startup string settings can easily be 
altered during configuration - see 
 for more details. The 
other serial settings are fixed at: No parity, 8 bit word and 1 stop bit.
