The following drawing shows the A4I board’s I/O connections.
The A4I board has jumpers that allow customization. If the A4I board is connected to additive meters for
which the transmitters require DC power, the voltage select jumpers (see Table 14: A4I Jumper Settings)
are used to set the meter power supply voltage to 5, 12, or 24 VDC.
Firmware updates are not available over serial connections in the A4I.
