The IP232 supports an easy method for forcing it from a static IP address to DHCP mode or vice versa. This is accomplished with the use of the DEFAULT Jumper located near the DB9M connector.
1. Power down the IP232. Carefully remove the plastic housing. Place a shorting jumper across the two pins of the DEFAULT Jumper. Power the IP232 back up.
2. After a few seconds, the green LED will blink and repeat in a ìcodedî fashion, indicating either DHCP or STATIC modes. If set for DHCP mode there will be 1 quick blink. If set for STATIC mode there will be 2 quick blinks. When the IP232 is forced to STATIC mode its address will become 192.168.0.251.
3. If the blink indicates the wrong mode, power the unit down and back up to force it to the opposite setting.
4. When the green LED indicates that the IP232 is at the desired setting, remove the shorting jumper and allow the IP232 to continue booting up. This may take a few seconds.
