e. Move the Data Highway cable from the MTL831B to the MTL831C. If two Data Highway cables
were used with the MTL830B system, select one of the two cables to use with the MTL830C
system. The second Data Highway cable is not connected.
f. On the MTL831C replacing the MTL831B with address 2 (if there is one), install a jumper wire
between the ADDRESS terminals A and S (terminal numbers 7 and 8).
4. If an MTL3052 Isolator is installed in the Data Highway cable, replace the MTL3052 Isolator with the
MTL5553 Isolator/Power Supply (see the MTL5500 Series Instruction Manual (INM MTL5500) for details).
5. Replace the MTL838B-HON with MTL838C (see the MTL838C Receiver Instruction Manual (INM
MTL838C) for details).
a. Move the MTL838B-HON RS-485 ports to the corresponding terminals of the MTL838C.
b. Move the wires from the MTL838B-HON Data Highway port to the corresponding terminals
of the MTL838C. If two Data Highway cables were used with the MTL830B system,
connect the same cable attached to the MTL831C Data Highway port(s) to the MTL838C Data
Highway port. The second Data Highway is not connected.
c. Move the wires from the MTL838B-HON power port to the corresponding terminals of the
MTL838C.
6. Apply DC power to the MTL830C system (turn on power to the MTL838C and MTL5553, if
installed).
7. Verify the MTL838C green POWER LED turns on.
8. Verify the MTL838C green COMM LED is flashing. This indicates communication is established
with the MTL831C(s). If not, verify proper connection of the Data Highway wiring.
9. Install the MTL83xC Configurator software on a computer.
10. Connect the computer to the MTL838C USB-C port.
