IP address setting
In order to use the SymNet1 correctly you must change the IP addresses from the defaults to ones that your
specific network will recognize. This requires a serial cable (provided) and a connection to a PC.
Serial cable
To make a serial connection, see Figure 4 and Figure 5 and do the following:
1. Orient the 20-way terminal connector with the 20-way socket side down and the keying ridge facing
away.
Note: If the serial cable is already connected to the terminal connector go directly to step 4.
2. Insert a small slotted screwdriver into pin 15 on the 3rd row down . Push the screwdriver until it
bottoms out. Insert the blue/white wire into pin 15.
3. Repeat step 2 with the blue wire in pin 16 and the orange/white wire in pin 20.
4. Clip the ferrite sleeve (provided) on to the serial cable.
5. Insert the connector into the I/O socket on the SymNet1 and insert the DB9-M end into the serial port
(COM1) of your PC.
