If the IQ4xx is to provide connection to the network for
supervisors and tools it is necessary to setup the RS232
Supervisor Port or USB Engineering Port as required.
Normal operation indication
LAN built OK
Attempting to build LAN
Note: It is normal behaviour for LAN OK indicator to extinguish
for up to 1 min after detecting baud rate, then illuminate.
Fault indication (
Ethernet LAN)
Unable to communicate on LAN.
Note: Only applies if current loop is
disabled or is not fitted.
Fault indication
(Current Loop LAN)
every 15s Longer than 2 minutes indicates
LAN/internetwork cannot be built.
▪
Check baud settings of all devices on current loop – see
step 21, and check all device connections.
▪
If still flashing, fit loop back:
85
84
86
87
RX- RX+
TX- TX+
If indicator turns OFF, device is faulty. If ON, reconnect
network and switch off all other devices on the network.
▪
If still OFF, check network cabling for short circuits with
a multimeter (NOT Megger).
▪
If ON switch on other devices in turn until faulty device
found (i.e. LAN OK goes OFF), inspect that device to
determine and and correct the fault.
By default the IQ4xx will auto detect the baud rate in use on
the current loop. If all devices are set to auto detect the baud
rate chosen cannot be guaranteed, in which case it may be
necessary to manually set one device to a known rate.
Use SET’s IQTool Monitor Applet to disable autobaud and
specify the baud rate.
