IR Remote Control Setting：
This device could use IR remote control for advanced function setting and control, The ID number must be
setup before using IR remote control or change new batteries.
Setup IR remote ID number: Press and hold “Power Symbol” button and press number 1,
Below is the IR remote control setting method:
Power Symbol When Device No = 0, could on/off the control mode.
When Device No = 1 – 32, mean turn off the control mode.
＊ n ENTER Input the number you want to setup (Device No)，n = 0-32,
Once the setting device into control mode, POWER LED will flash,
If you do not do any operation within 1 minutest, it will auto off control mode.
＃ n ENTER Input the Channel number you want to control (Channel No), n = 1-8,
The setting channel LED will be on, others will be off.
1111111 Select the control channel
A Manual setting Equalization mode for different cable distance (Sharpness)
Press A to use ▲ ▼ adjust the cable distance setting, total 64 adjustments.

Function Setting & Management application：
Function Setting & Management application：
This device could use command line to control via built in RS485 terminal program, (CLI，
Command-Line Interface), through RS485 terminal port (Console Port) for detailed function
setup and management. You could use our model number: RS003 USB to RS485 converter, or
RS001 RS232 to RS485 converter, the Communication format is 9600,8, N, 1 (9600 bps, 1 start
bit, 8 data bits, 1 stop bit).
Use command as below：

Trouble Shooting：
1. When control over one piece of TPA008A, each device must setting the individual Device Number to
avoid any confusion or failed control and management.
2. Please remember save any new change/setting in order to operate the new setting correctly.
3. If using multiple TPA008A with RS485 series control, the last TPA008A device must add 120Ω
termination resistors at terminal port (Console Port) in order to stabilize the data signal.
4. Long distance transmission or have interference occurred that might cause Equalization function not
correct or not able to do auto gain correctly, even not able to lock auto gain. The picture occurred the
“light and dark” alternating, recommend using manual Equalization setting for adjustment.
5. Long distance transmission or have interference occurred, the auto recognize signal polarity and color
may be failed; recommend to use manual setting according the actual signal format.
