For example, if pin numbers 2, 3, and 4 are all ON, the total is 7, which corre-
sponds to a baud rate of 115,200 bps.
Supplies 24-VDC (allowable voltage range: 20.4 or 26.4 VDC) power to the
WT30 Terminal. The terminal construction uses a screwless terminal block
(Phoenix Contact: FFKDS/V1-5.08 or equivalent).
The serial terminal construction uses D-sub, 9-pin (female) inch screws
(OMRON XM2F-0910-132 or equivalent)
Install an Antenna on both the right and left sides. Always use two Antennas.
