Clear CMOS Jumper (CLRTC)
The CMOS RAM data contains the date/time and BIOS setting
information. CMOS is powered by the onboard button cell battery.
To erase the CMOS RAM data:
1. Disconnect power from the M-322
2. Short the CLRTC pins 2-3
3. Turn the power on. After power on, remove the jumper
cap from pins 2-3 and reinstall it to pins 1-2.
COM1-4 RI, +12V and +5V Select (JCOMPWR1-4)
These jumpers allows you to select RI, +5V and +12V power set-
tings for COM1-4. Jumper JCOMPWR1 corresponds to COM1,
JCOMPWR2 corresponds to COM2, and so on, respectively.
