8. Will DevicePort® lower my Internet performances when access COM serial data at
the same time?
Answer:
SUNIX DevicePort® product built-in dual 10/100 Ethernet channels, one for data
downstream to PC host and the other upstream port to Ethernet switch. User can access
internet over DevicePort® bridge. Serial data communication asks very low bandwidth;
most of serial devices asks 9600bps,N,8,1 data transfer rate, so it should not cause your
internet accessing trouble. According to our testing, one single 8-port RS-232
DevicePort® product expenses about 10Mbp/s data transferring rate with full loading
(921Kbps, N,8,1) test. About 10% bandwidth of standard 10/100Mb network
environment.
However, to make sure efficient and safe communication, DevicePort® will put serial
communication data from COM ports as the first priority than other internet data
packages.
9. May I know system resource of COM or LPT port?
Answer:
SUNIX DevicePort® is an Ethernet enable devices. System or BIOS will not allocate any
resource for COM or LPT ports. So COM port does not locate at any legacy ISA address
3F8, 3E8, 2F8,2E8 and LPT port does not locate at 378, 278, 3BC legacy ISA address
either.
