• Description: Engine-to-controller communication error
  The controller sent a frame to the main machine engine but there was no response as demanded by RAPI protocol. The frame was sent 3 times at 100 ms intervals. This SC was issued after the 3rd attempt failed.

• Description: NRS Modem Communication Error
  One of the following factors could be the cause of this error: • In the User Tools, check the settings for the dial-up user name and dial-up password. • Modem has been disconnected. • Modem board disconnected.
• Causes: Check the following for a machine that is using Cumin (NRS modem): • An error was returned during the dialup connection • A network was detected at startup • At startup, the machine detected that the NIB was disabled, or did not detect a modem board
• Remedy: 1 Failure to certify dial-up In the User Tools, check the dial-up user and dial-up password settings 4 Illegal modem setting Check the setting of SP5816 160 to determine whether the setting for the AT command is correct. If this SP setting is correct, then the problem is a bug in the software. 5 Poor connection due to low power supply on the line. The problem is on the external power supply line, so there is no corrective action on the machine. 11 Data in the NVRAM became corrupted when the network enable switch and Cumin-M were enabled at the same time. Use SP5985 1 and set the NIC to "0" (Disable) to disable the network board. 12 The modem board could not enable the NIB. Replace the modem board.
