If at some point a 4100-iSIC no longer responds to iChart software, there are a few steps to follow to troubleshoot the connection:

1. First, make sure the COM port selected in iChart is correct.

2. Next make sure the base station is powered and operational.

  • For a 4100-base, make sure the RS232 cable is plugged into the iChart computer and the AC adapter is plugged into a working AC outlet.
  • The antenna and RF cable should be undamaged and appropriately mounted

3. Next cycle the iSIC by removing the two fuses inside of the iSIC enclosure for a few seconds and then reconnecting them. After cycling the power, wait a few moments for the iSIC to restart and iChart to connect to it. A green flashing light in the LED hole should be seen during restart.

4. Underneath the iSIC mounting plate is a spread spectrum radio modem. This modem has status lights that indicate if the modem has power, signal, etc.

Inside of the 4100-iSIC enclosure, there will be radio lights on the top of the enclosure behind the iSIC plate.

On the right hand side there should be a solid green light. This means that the radios can connect to each other. On the left hand side there should be a red blinking light; this is the radio signal strength. The faster the red light is blinking, the greater the signal strength up to a solid red light. If there is no solid green light, then either the 4100-iSIC cannot communicate to the base station because of distance or antenna connection, or the base station is not powered or connected to the antenna.
