2.2 Power/Data Connector
25 requires five volts for the standard display module, between nine to fifteen for the wide voltage (V)
and between nine to thirty-five volts for the wide voltage with efficient power supply module (VPT). The
voltage is applied through pins one and four of the four pin Power/Data connector. Pins two and three are
reserved for serial transmission, using either the RS-232/TTL or the I
been selected by the Protocol Select Jumpers. Pins two and three may be reversed by changing the Legacy
Connector Jumpers in order to be compatible with previous PCB revisions.
2.3 Protocol Select Jumpers
display module between RS-232, TTL and I
with solder jumps on the 232 jumpers. In order to place the display module in I
remove the solder jumps from the 232 jumpers and then place them on the I2C jumpers. The display will
now be in I
to change the display to TTL mode, simply remove the zero ohm resistors from the 232 or I
solder them to the TTL jumpers.
