Connecting and Configuring the TP-185
8
1. Connect up to eight VGA/WUXGA computer graphics sources (for example,
multimedia computers) to the Video INPUT 15-pin HD connectors.
2. Connect up to eight unbalanced stereo audio sources (for example, the audio
source of the computer or a DAT player) to the eight AUDIO INPUT 3.5mm
mini jacks.
3. Connect the eight OUT STP/UTP connectors to up to eight TP receivers.
4. If required, you can connect a PC and/or controller to the:
 RS-232 terminal block (see
Section 6.2
 RS-485 terminal block (see
)
Section 6.3 and Section 6.4
5. Connect the power cord

6.2 Connecting to the TP-185 via an RS-232 Connection
To connect the RS-232 port on the TP-185 to an RS-232 device:
1. Connect the RS-232 Tx pin on the TP-185 to pin 2 (9-pin D-sub) on the
RS-232 device
2. Connect the RS-232 Rx pin on the TP-185 to pin 3 (9-pin D-sub) on the
RS-232 device
3. Connect the RS-232 G pin on the TP-185 to pin 5 (9-pin D-sub) on the
RS-232 device
6.3 Connecting to the TP-185 via an RS-485 Connection
You can operate the TP-185 via the RS-485 port from a distance of up to 1200m
(3900ft) using a PC equipped with a card that provides an RS-485 port.
To connect a PC or controller to the RS-485 port on the unit:
1. Connect the pins on the following ports:
 Connect the A(+) pin on the RS-485 port of the PC to the A
pin on the RS-485 port on the rear panel of the TP-185

Connect the B(–) pin on the RS-485 port of the PC to the B pin
on the RS-485 port on the rear panel of the TP-185
 If required, connect the GND pin 2
2. If this is the only TP-185 on the RS-485 bus, set the RS-485 TERM
DIP-switch (see
on the RS-485 port of the
PC to the G (ground) pin on the rear panel of the TP-185
Section 7.1.1 ) to ON (for RS-485 line termination with
120
Ω).
1 We recommend that you use only the power cord that is supplied with this machine
2 For RS-485 communication, the ground is usually not connected between the devices. When using a shielded cable, the shield may be
grounded on one side
