Front View
Please note that the LED indications may change, once specific network communication soft-
ware has been downloaded to the module. When the network communication software has
been downloaded, the Network Status LED (labelled L1) and the Module Status LED (labelled
L2) must in many cases be relabelled to conform to specific network certification requirements.
Relabelling can be done by the customer or with interchangeable network specific fronts pro-
vided by HMS. Contact HMS for more information.
