| A recent customer had a working I-O 8494 Remote controller driving a combination of three twinax terminals and two printers. On one twinax port the customer had a single Decision Data (DData) dot-matrix printer with only one twinax turret.
The other twinx port on the 8494 was connected to an Orthonics Star Panel. This star panel then drove three twinax terminals attached via balans and twisted pair wiring. Hung off one terminal's parallel port was an Okidata dot-matrix printer. The customer wanted to replace the 8494 with an I-O 5794ip but specifications on the 5794ip controller state if using a star panel / twisted pair and balan setup only side one of the pigtail can be used, effectively limiting the number of total devices to seven. This also meant the DData printer could not be connected on it's own dedicated port / side of the pigtail. Under all conditions, the DData printer would not connect through the Star panel and back to the AS/400 unless there were no other devices attached to the Star Panel. However, if the DData printer was the only device connected to the Star Panel the setup worked fine. Introducing any other device to the Star Panel when the DData printer was attached effectively disconnected the printer from the Star Panel. This problem was solved immediately when the DData printer's parallel port was selected, the printer was connected directly to an I-O 5430 PrintServer and the I-O 5430's parallel port speed "slow output" option was selected. The DData printer works fine via the I-O 5430 and the Orthonics Star Panel with the attached terminals and printer worked as desired through the I-O 5794ip. |
