3.2 Ethernet
The DSLH card acts as a SIIS layer 2 managed Ethernet switch. Two copper Ethernet ports CU1 and CU2 are
accessed via the backplane 96-pin connector and the third Ethernet port is accessed via the installed SFP
(optical or copper depending on the type of SFP installed). Ethernet configuration options are typically performed
through the diagnostic GUI.

3.3 Serial
The DSLH card provides access to two serial ports. Each serial port supports RS-232, RS-485 or RS-422
protocols and are software configurable. The 120 ohm termination for the RS-485 interface can be
enabled/disabled via software and by default the termination is disabled.
The DSLH has two dedicated microcontrollers (uC1-2) to provide an Ethernet-to-serial gateway and each uC
can be configured in one of four modes: UDP gateway, Modbus gateway, PPP or disabled. All microcontrollers
on the card support in field firmware upgrades which can be performed via the sample GUI software.
