• Enabled - Toggle On to make this recorder a Master device
• Poll Rate - Enter a time period in seconds of how often there is a request for data
• Legacy Ethernet - Tick this to connect to
Honeywell V5 recorders.
• Slave 1 ..32 - Up to 32 slaves can be setup per master device. Setup each Slave in turn
starting with number 1.
• • Enabled - Toggle On to enable Slave #
• • Friendly name - Enter a name to easily identify this slave device
• • ID - This is to connect to slave ID
• • Port - Select this for a list of available ports, either Ethernet or RS485. For port

“System” on page 156
for the recorder’s IP address and serial number.
• • Protocol - Select this for a list of available protocols. Modbus or Modbus X*.
Modbus and Modbus X can both use Ethernet or RS485 Ports. Protocols define
the format in which the data is transferred from the recorder to a PC or transfer
between other devices and peripherals. FPLB – Floating Point Little Endian

float.
X Series devices use IEEE float.
Start Addr. - This is the register address number to start the transaction from
No. Of Items - Enter the number of items from the start address that are
included in the transaction. For example displayed here will be
10 SCV[1,1,1] - [1,1,10].

Serial Comms variable of Slave [1], Transaction [1], Register [1] - to Slave [1],
