2. Also pins 2 and 3 are reversed between the programmer port and the show control
ports 1-16.
3. There are additional pins on the show control ports 1-16 that are not present on the
programmer port. The additional pins on these ports are for supporting the RS-
422/485 functions. Note: The V16Pro RS422 TXD signals are reversed from the
V16+
4. Finally, the +9-volt pull up supply is on pin 8 of the programmer port and on pins 4
and 7 on the show control ports 1-16.

Ethernet Ports
The 2 Ethernet ports on the V16Pro do not have data pass-thru capability and cannot be
used as hubs, switches or routers. Both ports can be show or programmer ports. If your
control is assigned to one of the other programmer ports, you may have two independent
show control network ports if needed. For additional information on configuring and
using Ethernet see the sections on Ethernet and Networking Primer at the end of this
manual.
There are many protocols associated with networking, as applied to the V16Pro; the ones
of interest are UDP, SNMP, NTP, TCP, SMTP, HTTP and FTP. Because these ports are
true Ethernet ports in every way, there is nothing in the hardware that prevents these ports
to be swapped.
Ethernet Cables
There are two types of Ethernet cables, they are known as patch cables and crossover
cables. The connector is auto sensing so either one will work with the V16Pro.
