being processed. When these characters are displayed, RAID SYSTEM will halt requests from
the host (see above).
Fix: Make sure the
Write Buffer

buffer during system shutdown.

Remote terminal problems
Unable to access Configuration Mode using the remote terminal interface.
Possible Cause 1: The terminal communication settings do not match the settings of the RAID
SYSTEM RS-232 interface.
Fix: The default settings for the RS-232 port are 19,200 Baud rate, 8 Data bits, 1 Stop bit, No
Parity, and XON/XOFF Flow control. Make sure the terminal is configured for these settings. If
the settings were changed in Configuration Mode, verify the settings of the RAID SYSTEM in
the RS-232 Params, Terminal option and change the terminal settings accordingly.
Possible Cause 2: Incompatible RS232 cable.
Fix: Cross pins on the RS-232 cable as shown below (or use a null modem cable). The only pins
used are 2 3 & 5.
