Configuration of SNTL150-P via TTL
In order for customers to transmit their own remote profiles to the SNTL150P, the following protocol must be
used:
Packet must be sent in the following format
[Byte1] Node Address must be that of the charger (Preset of 100)
[Byte2] Write Multiple Registers (0x10)
[Byte3] Starting Address (High Byte)
[Byte 4] Starting Address (Low Byte)
[Byte 5] Number of Registers {High Byte)
[Byte 6] Number of Registers (Low Byte)
[Bytes 7 – 20] Data as per below
Register start address = 11
Number of points = 7
Register SNTL150P Function Scaling
40011 Float voltage Voltage X 10
40012 Boost voltage Voltage X 10
40013 Boost initiate voltage Voltage X 10
40014 Boost period Minutes
40015 Low alarm voltage Voltage X 10
40016 High alarm voltage Voltage X 10
40017 (High Byte) Number of cells Cells X 1
(Low Byte is reserved, the value stored
must be read and then rewritten to
SNTL150P when updating profile)
The confirmation message back will match Bytes 1 – 6 of transmitted message. Changes are made instantly.
