The data select switch (left switch) lets you choose between data transmission (TX) or reception (RX) for the POS/ATM device’s
output. Set the switch to the TX position (factory default) when connecting directly to the device’s DB25 output port. If
connecting to the device’s existing output data cable, you may have to change the switch to the RX position if you are not using
a straight data cable.
For an ATM network connection, the data clock select switch (right switch) lets you choose between the ATM network’s
transmit (TCK) and receive (RCK) clock. You may have to change the switch position depending on the type of network
connection being used.
The data select and data clock select switches typically should be set to the same position (both transmit or receive).

Switch SW1 lets you choose between data transmission (TX) or reception (RX) for the POS/ATM device’s output. Set the switch
to the TX position (factory default) when connecting directly to the device’s DB9 output port. If connecting to the device’s
existing output data cable, you may have to change the switch to the RX position if you are not using a straight data cable.
The three SW2 handshake switches let you enable RS-232 hardware handshaking for the device’s data port. Set all three to ON
(up) to enable and all three down to disable.
