ACR8010 MOTHERBOARD JUMPERS
RS-422/485 Configuration Jumpers (JP1, JP6, JP9, JP10, JP13, JP14)
The ACR8010 serial communication interface is software configurable. At power-up, the
default COM1/COM2 communications mode is RS-232.
ACR8010/SA Boards:
For Standalone ACR8010 boards, reconfiguration of the communications ports to
RS-422/RS-485 must be performed via an RS-232 port.
If one of the serial ports is a dedicated RS-232 port, reconfiguration of the second port
may be accomplished at power-up (or at any time).
If both ports are to be configured to RS-422/RS-485 mode, the following must be
performed:
1.
Open serial communication to one of the ports via RS-232.
2.
Load a PBOOT program containing the desired communication flags
configuration for COM1 and COM2 ports.
This will configure the serial ports to the desired mode of operation at power-up. If a
different communication mode is then required, disabling the User-Memory battery-
backup batteries via jumpers or a issuing a BRESET command (or issuing a FLASH
ERASE command, if the programs are stored in flash memory) will set the
communications modes back to default (RS-232) at the next power-up sequence.
ACR8010/PS Boards:
For PC ACR8010 boards with the communications option, the serial ports may be
configured as above via a serial port, or at power-up (or any time) via the ISA bus
communications port.
