RS232(2) mode [ DIRECT / MODEM (HW) / MODEM (SW) / MODBUS-
DIRECT / MODBUS-MDM(HW) / ECU LINK]
Communication protocol selection for RS232(2) line.
Description is the same like for RS232(1) mode.
Available only in IS-NT and in IG-xxC versions.
Hint:
Detail description of Modbus protocol see in Communication guide.
ECU LINK mode can be selected only at RS232(1) port.
ECU LINK mode available only starting from FW versions IGS-NT-2.2 or higher together with IGS-NT-E-
COM-1.1 or higher.
RS232(1)MBCSpd [ 9600 bps / 19200 bps / 38400 bps / 57600 bps ]
Defines the communication speed on RS232(1) line when ModBus mode is selected.
RS232(2)MBCSpd [ 9600 bps / 19200 bps / 38400 bps / 57600 bps ]
Defines the communication speed on RS232(2) line when ModBus mode is selected. Available only in IS-NT
and in IG-xxC versions.
RS485(1) conv. [ DISABLED / ENABLED ]
If set to ENABLED, the communication RS232(1) port is redirected to the built-in RS485 converter (IG-
Display connector).
Hint:
Applicable only for DIRECT, MODBUS-DIRECT and ECU LINK modes.
This converter is not isolated!
For ports position and description see Installation guide.
RS485(1) has to be swiched to Disabled when IG-Display (Remote Display) is used.
RS485(2) conv. [ DISABLED / ENABLED ]
If set to ENABLED, the communication RS232(2) port is redirected to the built-in isolated RS485 converter.
Available only in IS-NT and in IG-xxC versions.
Hint:
Applicable only for DIRECT, MODBUS-DIRECT modes.
RS232(1)MdmIni [ ]
Auxiliary modem initialization string – executed after the default modem initialization string. Used with
modem connected to the RS232(1) communication port.
Hint:
Applicable only for MODEM(HW), MODEM(SW) and MODBUS-MDM(HW) modes.
Use for special AT command setting of your modem if default string does not initiate the modem properly. AT
commands must be separated using semicolon “;”, max. length 31 characters.
The setpoint can be changed only using PC SW when configuring IG-EE/NT.
RS232(2)MdmIni [ ]
Auxiliary modem initialization string – executed after the default modem initialization string. Used with
modem connected to the RS232(2) communication port.
Available only in IS-NT and in IG-xxC versions.
Hint:
Applicable only for MODEM(HW), MODEM(SW) and MODBUS-MDM(HW) modes.
Use for special AT command setting of your modem if default string does not initiate the modem properly. AT
commands must be separated using semicolon “;”, max. length 31 characters.
The setpoint can be changed only using PC SW when configuring IG-EE/NT.
CAN bus mode [ 32C / 8C ]
CAN bus speed selection.
32C: High speed CAN (250 kbps) applicable up to 32 controllers, CAN bus length limited up to 200
meters.
