Data Line 1 – Routes V2923ACN CPU control signal to pan/tilt,
lens, and auxiliary functions at suitably equipped sites, up to
1024. Data Line 1 also routes the matrix switching information
for video outputs 1- 64.
2.
Data Line 2 – Routes V2923ACN matrix switching information
for video outputs 65-128.
3.
RS-232 PORTS - These ten RS-232 ports provide interfaces for
communication with keyboards, PCs, and other devices such as
the V2431 Alarm Interface Unit. Each port is programmable for
baud rate, data bits, stop bits, parity and type of use.
4.
Ethernet Port - This Ethernet port is used to connect V2923ACN
to a Hub or switch via UDP to form a network video system.
5.
PROG MON - The output for the system programming monitor
(PROG MON) that displays programming menus.

2.2 Hardware Connection
All internal switch settings on the modules should be made before
system connections are started. Ensure that all connections are
properly completed before applying power.
To facilitate maintenance and assist in service, all connecting cables
should be identified with source/destination numbers.
2.2.1 Communication Port Connections
The External CPU of V2923ACN each provides ten RS-232
communication ports for connection with auxiliary equipment, e.g.,
keyboards, controllers, computers and alarm interface units.
The ten RJ-45 communication ports are respectively labeled as
PORT 1 through 10, and are expandable up to 40 ports with
V2405A-4 series port expanders.

Note:
All the RS-232 ports are configured with the following
default settings: baud rate - 1200, parity bit - none, date bits - 8,
stop bits - 1.
Standard Terminal Boxes (Figure 2-3) are provided for
communication port connections. Their pin definitions are detailed
in the following table.
