RS-232

WEB MANAGEMENT INTERFACE REFERENCE

The RS-232 serial-over-Ethernet feature can be used for remote control of a distant

serial device via the Wave Relay

network. A typical application is for a local PC to

control a distant pan/tilt camera via a serial link. If the PC and camera cannot be

colocated, then two Wave Relay

devices can be used to connect them (similar to an

old-fashioned modem-to-modem link). Thus, the serial port on the local PC can be

hardwired to a local Wave Relay

device and the serial port on the distant camera

can be hardwired to a distant Wave Relay

device. Communication between the two

devices is then relayed via the Wave Relay

network. This is called “serial-to-serial

mode.”

Alternatively, the PC can run emulation software that allows it to create a local

virtual COM port that is conﬁgured to communicate directly with a distant network-

enabled serial port (e.g. as described in RFC 2217). Thus, the distant camera is

hardwired to a distant Wave Relay

device and the local PC can then connect

directly to the distant device via Ethernet. This is called “virtual-to-serial mode.”
