When using the SmartController in an AUTO Boot configuration, DIP switch SW1 must 
be set to the switch settings shown in row #5 of 

 and the NVRAM switches set for 

AUTO boot.

The SmartController CS has two serial I/O connectors, an RS-232/Term and an 
RS-422/485 port. See 

 for the connector locations. 

The SmartController CX has two additional serial connectors, RS-232-1 and RS-232-2. See 

 for the connector locations.

All three of the RS-232 connectors are 9-pin DB9 male (standard PC) connectors. The 
user-supplied cable to connect to the RS-232 connectors should be a DB9, F/F, 
null-modem data transfer cable. The pin assignments are the same for all three connectors 
and are shown in 

These ports support the DTR, DCD, RTS, and CTS signals used for hardware handshaking 
(also known as modem control). By default, these signals are not enabled. To configure 
hardware handshaking and other communication parameters, use the CONFIG_C utility 
program, the V

+

 FSET program instruction, or the FSET monitor command. The V+ 

designations for these ports when referenced in a V

+

 ATTACH or FSET instruction are 

shown in 

. 

If you are using a customer-supplied ASCII terminal, it plugs the RS-232/Term connector 
on the SmartController.
