5.1CMOS Jumper Settings J1

Jumpering J1 will reset the CMOS. If users experience problems booting up the Morpheus they should reset the CMOS RAM, which will restore the BIOS settings to factory defaults. To clear the CMOS RAM, power the board down, install the jumper as shown, wait a few seconds, then put the jumper back into the default setting. Then power up the Morpheus again.

Default Setting (1-2 on)

Setting to clear CMOS RAM (2-3 on)

Serial port 2 on Morpheus can be configured to operate in RS-232, RS-422 or RS-485 protocols, while port 1 is fixed RS-232. Jumper J5 determines the serial protocol for port 2. To configure the protocol, power down the CPU, install the jumper in the desired location, then power up the Morpheus again. For serial port pinouts, please refer to section 6.1, page 8.
