iMPACT 13.x/14.x - Parallel Cable IV is recognized as Cable III

Description

The parallel port of a laptop is usually expanded by a dock. When Parallel Cable IV is plugged, it is recognized as Cable III in iMPACT. If using cable setup to select PC4 and a different cable speed, the following message is shown:

// *** BATCH CMD : setCable -port lpt1
Connecting to cable (Parallel Port - LPT1).
Checking cable driver.
 Driver windrvr6.sys version = 10.2.1.0. WinDriver v10.21 Jungo (c) 1997 - 2010 Build Date: Aug 31 2010 x86_64 64bit SYS 14:14:44, version = 1021.
 LPT base address = 0378h.
 ECP base address = FFFFFFFFh.
Cable connection established.
Connecting to cable in compatibility mode.

Solution

For Win7/WinXP,  add this environmental variable:

XIL_IMPACT_ENV_LPT1_ECP_ADDRESS = 0778

Reopen iMPACT, PC4 can be recognized properly like this:

Connecting to cable (Parallel Port - LPT1).
Checking cable driver.
 Driver windrvr6.sys version = 10.2.1.0. WinDriver v10.21 Jungo (c) 1997 - 2010 Build Date: Aug 31 2010 x86_64 64bit SYS 14:14:44, version = 1021.
 LPT base address = 0378h.
 LPT1 Ecp Address set from env variable = 778.
 ECP base address = 0778h.
 ECP hardware is detected.
Cable connection established.
Connecting to cable (Parallel Port - LPT1) in ECP mode.
Checking cable driver.
 Driver xpc4drvr.sys version = 1.0.4.1. LPT base address = 0378h.
 LPT1 Ecp Address set from env variable = 778.
 Cable Type = 1, Revision = 3.
 Setting cable speed to 5 MHz.
Cable connection established.
PROGRESS_END - End Operation.
Elapsed time =      3 sec.
