Setting the RS232

(DCE). This switch changes the transmit and receive pin functions on
the RS232 connector on the back of the meter. Use the steps below to
properly set the switch.
1. Remove the screws on the front panel and slide the electronics unit
out of its enclosure.
2. Locate the RS232 switch on the display board. Use Figure 1-14 to
locate the switch.
3. Set the RS232 switch to the desired position. Set the switch to
DTE if the unit will be transmitting data or DCE if the unit will be
receiving data.
Note: If communications do not work properly, try changing the
RS232 switch position.
