Connecting the TP-145 and the TP-146

An RS-232 cable with a 3 pin terminal block connector at one end to the TP-146RS-232 port1, and a 9-pin D-SUB connector at the other end to the RS-232 port on the AV display system

3.Using STP cabling2, connect the LINE OUT RJ-45 connector on the TP-145to the LINE IN RJ-45 connector on the TP-146.

4.Connect the power adapter to the power socket on the TP-145and/or TP-146(if needed), and connect the adapter(s) to the mains electricity.

5.On the TP-146:

If necessary, adjust the video output signal level and/or cable compensation equalization level with a flat screwdriver

If necessary, set the horizontal sync switches, vertical sync switches, and the sync mode jumpers (see Section 4.2.1)

5.1Transmitting via RS-232

It is possible to transmit data (for example, using a PC) between the TP-145and TP-146via the RS-232 terminal block.

Prepare an RS-232 cable with a 9-pin D-sub connector at one end, and a 3 pin terminal block at the other end as defined in Table 4 and Figure 5.
