Register Sensors To SMG
DO NOT INSERT BATTERIES UNTIL SENSOR HAS BEEN REGISTERED.
In order for the Serial MODBUS Gateway to go active, you will
need to register at least one wireless device. When registering
your rst device, the gateway will need to time to form a net-
work, which takes 30 seconds. The gateway will be unavail-
able during this time period. After the rst device registration is
complete, any subsequent registrations can be one right after
the other, as the network only needs to form once.
Each Monnit device has a 32 bit serial identier and a 6 digit
verication code. Fill in the following registers with this infor-
mation.
WDREG_ID_H 40016 Wireless Device’s Identication Number of
a device that will be registered to the gate-
way’s Wireless Device List. (UInt32 value)
Example:
5005145 → _H = 0x004C, _L = 0x5F59.
WDREG_ID_L 40017
WDREG_CODE_1 40018 A string security code unique to a specic
Monnit Wireless Device ID. This value is
cross-referenced against the device ID
registers to successfully add the device to
the gateway’s Wireless Device List.
Example: “IMARVD”
CODE_1 = “I” → 0x49 or 73
CODE_2 = “M” → 0x4D or 77
CODE_3 = “A” → 0x41 or 65
CODE_4 = “R” → 0x52 or 82
CODE_5 = “V” → 0x56 or 86
CODE_6 = “D” → 0x44 or 68
WDREG_CODE_2 40019
WDREG_CODE_3 40020
WDREG_CODE_4 40021
WDREG_CODE_5 40022
WDREG_CODE_6 40023
