NTI SE-15V-2-2U1C-TTL, SE-15V-2-2U1C-RS, SE-15V-2-2C1U-TTL Installation Manual
INSTALLATION GUIDE FOR THE 2-PORT TTL VIDEO ONLY SWITCH
SE-15V-2-2U1C-TTL / SE-15V-2-2C1U-TTL/SE-15V-2-2U1C-RS
INTRODUCTION
The NTI 2-port “TTL” controlled video only switch allows one (1) CPU to switch two (2) monitors (model SE-15V-2-2U1C-TTL) or
one (1) monitor to be switched to two (2) computers (model SE-15V-2-2C1U-TTL). All NTI 2-port "TTL" controlled video only
switches are available for VGA video with 150MHz bandwidth and 1920X1200 resolution.
Optional: RS232 Control instead of TTL control available in model SE-15V-2-2U1C-RS.

4. Secure the power cable to the cable tie on the SE-15V-2 and connect the power plug from the AC adapter to the SE-15V-2.
5. Plug in the AC adapter and power-up the switch. The “Power” LED and “1” LED should illuminate, indicating a conn ection
between the monitor and the CPU connected to “Video 1”.
6. Apply power to the CPU(s) and monitor(s).

TTL Control (SE-15V-2U1C/2C1U-TTL Models Only)
Models with –TTL include a 9 pin D female connector port for remote control. The proper wiring of the 9DB connector to use this
port is as follows:
¾ Pin 1 = Ground
¾ Pin 2 = NC or connect toTTL1 (>2.4VDC) to switch to Monitor 1
¾ Pin 2 = Connect to pin 1 or TTL0 (<0.8VDC) to switch to Monitor 2.
The LEDs (1 or 2) will illuminate to provide indication of port selection

RS232 CONTROL (SE-15V-2U1C-RS Only)
The SE-15V-2U1C-RS can be controlled from the front panel push button (press to switch between MONITOR 1 and MONITOR2)
or it can be controlled using RS232. RS232 control can be achieved using a separate user terminal or CPU with a terminal
program. To make a terminal connection, connect a serial cable (specifications on page 3) between the user terminal and the 9
pin DIN female connector on the VIDMUX labeled "RS232". Configure the terminal program for a baud rate of 9600.

Remote Connection
The RS232 Interface is designed to meet the RS232C standard
and can be controlled from any CPU or other controller with an
RS232 communications port. The pin-out for the 9DB connector
on the unit is as follows:
On the 9DB female connector, pins 1 (DCD), 4 (DTR), and 6
(DSR) are shorted and pins 7 (RTS) and 8 (CTS) are shorted.
Therefore, host handshaking is bypassed and TXD and RXD are
