Input Connection Modes
RS485 Input Mode
The factory default input mode of the ERL-10 is setup to receive data from the
RS485 input on the terminal block from the EFA-21 power/data module. The diagram below
indicates the jumper settings for this input method. If switching from the fiber optic input,
access the circuit board by removing the four case screws and cover. The jumpers shown below
indicate the correct position.

Note:
the RS485 communication on the ERL-10 is one-way and can only receive data (default)
or transmit data depending on the jumper settings.
See connection diagram on next page for the default setup using this input method.
