Advantech ARK-7480 User Manual

This item allows you to enable/disable IR transmission delay. The 
choices: Enabled, Disabled.

This item allows you to select the IR half/full duplex function. The 
choices: Half, Full.

This field sets the address of the on-board parallel port connector. These 
fields allow you to select the IRQ of onboard serial port with their 
addresses, or you can select Disabled. The default values for parallel 
ports are: 378/IRQ7

This field allows you to set the operation mode of the parallel port. The 
setting “SPP” allows standard printer port device running at normal speed 
operation, but in one direction only. “EPP” allows bidirectional parallel 
port operation at maximum speed. “ECP” allows the parallel port to oper-
ate in bi-directional mode and at a speed faster than the maximum data 
transfer rate. “ECP + EPP” allows normal speed operation in a two-way 
mode. The default value of Parallel Port Mode is “SPP”.

This field allows you to select EPP port type 1.7 or 1.9. The choices: 
EPP1.7, 1.9. The default value is 1.7.

This selection is available only if you select “ECP” or “ECP + EPP” in 
the Parallel Port Mode field. In ECP Mode Use DMA, you can select 
DMA channel 1, DMA channel 3, or Disable. Leave this field on the 
default setting of 3.

This selection is allowed you to choose 3 options of “Off”, “On” or 
Former-Sts” for Power setting when abnormal electricity break occurs.
Off When power returns after an AC power failure, the system’s power 
is off. You must press the Power button to power-on the system.
On

When power returns after an AC power failure, the system will 

automatically power-on.
Former-StsWhen power returns after an AC power failure, the system 
will return to the state where you left off before power failure occurs. If 
the system’s power is off when AC power failure occurs, it will remain 
off when power returns. If the system’s power is on when AC power fail-
ure occurs, the system will power on when power returns.
