Configuration - Leviton ModHopper Installation And Operation Manual

5 CONFIGURATION

5.1 Modbus Address
Before the ModHopper can be used, you must set the Modbus address of
the ModHopper. This address must be unique among all Modbus devices in
the system including all devices that are connected on remote wireless links.
Address 0 (all switches off) is not allowed.
Select an address, and set the DIP switches to match.
The sum of the value of the switches is the address. In the example to the
right, address 52 is set by placing switch 4, 16 and 32 to the on position.
Note: 4 + 16 + 32 = 52
5.2 System Setting
For most systems, set all of the system switches to the "off" position.
Radio channel: This option selects the channel number that can be used to
isolate a group of ModHoppers. This option may be set for channels 0 to 6.
Channel 7 (all 3 switches on) is not allowed.
Programming: Set the "Prog Enable" to Off for normal operation.
485 Termination Enable: Set the "485 Term En" to ON to enable a 120 ohm
termination resistor on the RS485 network. This should be used when the
ModHopper is on the end of a 485 wiring run. Set this switch to OFF when the
ModHopper is in the middle of an RS485 wiring run.
Port RS232 or RS485: Set the switch to the "off" position for RS485 operation.
The ModHopper can communicate via the RS232 connection however most
Modbus devices will need 485 terminals.
Baud Rate: This option sets the serial port speed for the Modbus devices connected to the ModHopper.
Set this option to "off" for 19200. Set the switch to "on" for 9600 baud.
Reserved: Set this option to Off.
5.3 Status LEDs
The device should power up and be ready in a few seconds. The LEDs should
blink in the following manner.
• The "Alive" LED should start to blink about once per second.
• The Alarm LED will blink when transmission errors occur.
• The RF TX/RX LEDs will blink when the radio is receiving
or transmitting data.
• The RS485 LEDs will blink for local Modbus activity.
• The Pulse input LEDs will light when the corresponding pulse input
terminals are closed.
• If the device has the -SN option, the 400MHz LED will blink when an RF
packet from a 400MHz sensor transmitter is received.
