Power Supply BL-U1
84
Prepare the BL series for connection to the BL-U1 by soldering a D-sub 9-pin con-
nector to the BL series cable. Then connect the cable to READER port of the BL-
U1.
Prepare the D-sub 9-pin connector and its connector case separately.
Take special care when soldering pin 5 (GND) and pin 9 (+5VDC). A wrong con-
nection will damage the unit.
Do not use a power cable over 2 meters long. A long power cable can cause a
drop in voltage, preventing the BL series from starting up properly.

According to the selected interface and timing input, change the DIP switch set-
tings.
