Connect the HSS to a Serial Device
The Hyper SCADA Server (HSS001) features two ports (COM1 and COM2) for
connecting serial-type devices, including Modbus devices. These ports are
connected to the HSS' NIM, which allows the serial devices to pass their data to
network devices. This is accomplished through a process called serial
tunneling. In serial tunneling, the HSM bundles serial data into network
packets and forwards it to the NIM. When the NIM sees an incoming packet, it
switches
to serial tunnel mode, extracts the serial data, and sends the data out the
appropriate COM port. When a serial device sends data to one of the NIM’s
COM ports, the NIM bundles the data into network packets and forwards them
to the HSM.
COM1 and COM2 include RTS and CTS to support connections to equipment
(such as radios and modems) that require hardware handshaking. RTS and
CTS are optionally enabled via configuration of the driver in HT3.
Additionally, both COM1 and COM2 are used as stand-alone serial tunnels
only; there is no bus communication.
