Byte of the SECURITY_KEY. When the cryptography is enabled, all of the

devices of a single PAN ID should have the same value in this register.

Configures which Baud Rate will be used in the operation mode in the USB

interface of the device. In configuration mode, as described in chapter

Configuration Software, the device always Uses Baud Rate 115200.

0 – Baud Rate 1200

1 – Baud Rate 2400

2 – Baud Rate 4800

3 – Baud Rate 9600

4 – Baud Rate 19200

5 – Baud Rate 38400

6 – Baud Rate 57600

7 – Baud Rate 115200

R/W

Configures which Baud Rate will be used in the operation mode in the RS485

interface of the device.

0 – Baud Rate 1200

1 – Baud Rate 2400

2 – Baud Rate 4800

3 – Baud Rate 9600

4 – Baud Rate 19200

5 – Baud Rate 38400

6 – Baud Rate 57600

7 – Baud Rate 115200

R/W

Configures the parity and how many stops bits will be used in the operation mode

in the USB interface of the device. In configuration mode, as described in chapter

Configuration Software, the device always uses ParityNone_StopBits2.

0 - Parity None Stop Bits 1

1 - Parity None Stop Bits 2

2 - Parity Even Stop Bits 1

3 - Parity Odd Stop Bits 1

R/W

Configures the parity and how many stops bits will be used in the operation mode

in the RS485 interface of the device. To facilitate connectivity with devices from

different manufacturers, when configured with ParityNone_StopBits1 or

ParityNone_StopBits2, the device always transmits using 2 stop bits and receives

with 1 stop bit. This allows for communication with devices with both

configurations, but this feature is only available with the RS485 interface.

0 - Parity None Stop Bits 1

1 - Parity None Stop Bits 2

2 - Parity Even Stop Bits 1

3 - Parity Odd Stop Bits 1

R/W

Interframe is the time used to characterize the fact that 2 bytes are part of the

same Modbus frame (packet). When two bytes are spaced in less time than the

time configured in this register, they are part of the same packet. When this time

is exceeded, the frame is considered to be finished.

In this register the Interframe Modbus for USB is configured. When configured with

1749, it automatically takes on the values according to the Baud Rate in compliance

with the Modbus protocol. If the network master connected to the USB interface has

a high rate of errors, it is possible that it is not following the Modbus rule. In this

case, increasing the value of the register may solve the problem.

In this register the Interframe Modbus for USB is configured. When configured with

a high rate of errors, it is possible that it is not following the Modbus rule. In this

case, increasing the value of the register may solve the problem.

As explained in the chapter Configurations – AirGate-Modbus, this register is

used to configure the Modbus address, i.e., the address that identifies the device on

the network. As a standard, since it is a gateway and to not conflict with other

network devices, all of the AirGate-Modbus leave the factory with the address 248.

When in configuration mode, as explained in the Configuration Mode chapter,

the device always answers for the Modbus 246 address using the USB interface.

1 254 R/W

When operating in Multi-Master mode, as explained in the MULT-MASTER

chapter, the gateway uses the Multiplexar function that needs a time-out to

release the interface in case the response does not return to one of the masters.

The Time-out is configured in this register. This is the maximum amount of wait

time for a response from a slave
