RS232 Serial Interface
The same User I/O female high-density DB15 connector also provides for an RS232 interface
between the MINV and the host/system computer. The interface has a 115.2k baud with eight
data bits, no parity bit and one stop bit. The pin assignments and functions for this RS2332
interface are as follows:
Signal
Pin Number
Function
GND
4 and 5
Ground reference for RX and TX signals
RX
3
RS232 DCE/MINV Device Receive signal
TX
2
RS232 DCE/MINV Device Transmit signal
The RS232 port provides readback of MINV’s state, as well as the configuration and control
of the MINV’s operation. The port can be used from a standard terminal interface, or from a
custom computer application.
Readback information that is available:
• DC Input Voltage
• AC Output Voltage
• AC Output Current
• AC Output Power
• AC Output Frequency
• Total Output Power
• External Switch Input Status
• Fan RPM
• Internal Temperatures
Parameters that are controllable through the interface:
• Battle Mode
• Blackout Mode
• Alarm enable / disable
• Fan diagnostics
• On/Off Synchronization
• Output enable / disable
• Sleep Mode enable / disable
