Relays
The four relay outputs (labeled K1 through K4) are available through the
bottom 18-position removable Euroblock connector on the rear panel, as shown in
the picture in the preceding section. Each relay can be individually controlled from
the terminal to provide contact closures for external devices. The relay contacts are
rated for 1A at 30V (AC or DC), and are linearly derated to 0.3A at 120V. Both relay
contacts are electrically isolated from the unit.

Options Switch
The 10-posiiton rear-panel options DIP switches control fundamental oper-
ating settings such as the Unit ID, RS-232 Baud Rate, and Master/Slave Mode.
These switches are read only when the unit is powered-on or reset. The switch up
position corresponds to OFF, and the down position corresponds to On. The facto-
ry default settings for these switches are all OFF.
