Hi Bill,
We also use both the 1014D and 1014. Although I have not tried it for
several years, I think your evaluation is pretty accurate ... but one
can easily replace a 1014D with two 1014s.
By default:
A16 address for the #L0 card is 0x5000
A16 address for the #L1 card is 0x5200
The 1014D covers both address spaces if the base address is set to
0x5000, thereby servicing #L0 and #L1.
So, if you replace the 101D with two 1014s, you don't even have to
change your databases.

Greetings from STAR on LI,
We have three subsystems using NI 1014 type GPIB interfaces. All of
these have been running for many years, and all are using 3.12 EPICS.
One subsystems uses a 1014D, dual port interface. It was brought to my
attention that we have no spare for this system. I was looking into the
problems that would arise should we have to swap this with a 1014 mono
port interface. We have several spare 1014, and our other option would
be to buy another 1014D
From the code, and the device support, the startup scripts, and the
state programs we use for the two types of interfaces I see no real
differences. The only difference is in the record fields where the dual
port has two lines #L0 and #L1 in its database.
Would a swap only involve a database change? What hardware
considerations are involved? I have had no previous experience (up to
24 hours ago) with GPIB, and have been perusing the manuals, and tech
talk. Normally I would just play, but we are now buttoned up with beam
for this system, and wont have access for weeks.
Any answers, and suggestions are greatly appreciated.
Thanks in Advance,
Bill Waggoner

PS Eventually.. next year? we might upgrade this to EPICS 3.13 or
3.14.. but time constraints aren’t going to allow that for this run.
