Introduction
Ness "V" Series M1 Access Control Systems are flexible and scaleable to permit economic and high
performance access control solutions for a wide range of applications. Modules interconnect through
different sub-networks and protocols to a standard TCP/IP network with the capability of a variety of
applications.
For example, the "V" Series Network Controllers are a cost-effective method for two-way communication
using Ethernet between a computer and a V1000 or V2000. In addition, the V1000 can communicate
through a multi-drop RS-485 network to sub-controllers.

Cable Specifications
RS-485 Connections (V1000 only)
The V1000 has two - RS-485 connectors. The V1000 uses the 10-pin,
P3
and
P4
for the RS-
485 connections. Each RS-485 bus can support a maximum of 16 V100-Series using one or two ports.
Having two ports on each bus provides the option of splitting each RS-485 bus into two physical
connections, allowing a total of four physical connections for the two busses. RS-485 busses must be
connected in a daisy chain topology and not a star topology.
Note:
Each V1000 port and the end V100-
Series, whether it is single or a daisy-chain connection, requires a separate termination resistor jumper.
