Rotary Switch Function: for HKM02BT

HKM02BT built in rotary switch to set channel numbers follow 16 HEX, could switch “ 0 ~ F “ total 16 channels, A = channel 10, B = channel 11, others channel same as 16 hex conversion.
For channel numbers over 15 you could use panel button, IR remote, RS232, APP to set up.

RJ45 Pin Define
Video Link (TIA/EIA-568-B)

Cable & Transmission Distance

Link Cable use high quality CAT.5e UTP/STP/FTP or CAT.6 UTP cable Transmission distance will be affected by equipment (Switch HUB), cable quality…etc.
When using CAT.5e/CAT.6 cable connect transmitter and receiver directly without Ethernet switch, the maximum transmission distance up to 150M.

You can also use model no: SR01X repeater for extended longer distance or using Gigabit Switch hub which support IGMP protocol and Jumbo Frame 8K for signal distribution or extend distance.

System Default Casting Mode/IP Settings
Casting Mode

Transmitter / receiver support Unicast and Multicast two mode, default is Multicast.
In Multicast mode it could be one to one, one to multi, multi to on or multi to multi applications.
The analog audio output of transmitter and input of receiver will be off in this mode, analog audio only from transmitters send to receivers.
Unicast mode suitable for one to one or multiple transmitters to one receiver applications.
Analog audio bi-direction transmission only in Unicast mode.

IP Mode
System default IP setting is Static IP, IP mapping to last 4 digits of MAC address (Hex), for example MAC

We recommend Static IP mode when using APP or PC software control to prevent any IP change problem.

Bandwidth Chart
The bandwidth will be varied based on different resolution. Higher resolution may not request bigger bandwidth. Below Chart is the resolution and bandwidth status for reference.

Above bandwidth chart not include USB transmission, it cost up to 50 Mbps when transferring mass data.
System scalability is limited only by uplink and stacking connector bandwidths, for example under Gigabit Ethernet network, the total flow must not exceed 1000Mbps to avoid any delay on video streaming. If the video play with 1080p resolution, the transmitter allow maximum up to 7 pcs for simultaneous video streaming.
For 8~16 sources: use switches which support 802.3ad Link Aggregation or smart (or intelligent) switches to get 2 Gbps or more bandwidth.
For over 16 sources: use switches which support SFP+ uplink or stackable switches to get 10 Gbps bandwidth.

RS232 Control
In RS232 extender mode, user could use RS232 port of transmitters to operate/setup the receivers at same channel by program like Hyper Terminal which built-in Windows XP and before version.

Hyper Terminal setting:〔115200 bps (8-N-1), Flow control: None〕(Properties -> Settings -> ASCII Setup… and select “Send line ends with line feeds” &”Echo typed characters locally”)

We recommend set the RS232 routing for all receivers to one transmitter to avoid RS232 connection broken by video channel switching.

Command format: >CMD_Address> Command Parameters
Address, command and parameters are char, not hex code
Enter (LF or CR+LF) is required to execute the command
All accord receivers will run the command and parameters, we also add 3 kinds of user defined numbers except MAC & IP (Device No, Group No, Party No) for flexible application:

Response format: <ACK_Address< Response character
Receivers will response message to transmitter as above format and send Newline after
When send command to multiple receivers(address as Gxx, Pxx, Cxxx, and ALL) they will not response.
Example:

Troubleshooting

1. Transmitter/receiver boot time require 30 seconds and will be able to control after booting, First time reboot after reset to default will be longer than 30 seconds.
2. Not recommend to work with existing LAN connection to avoid large video, data transmission or multicast packets to slow down your other LAN devices.
3. Gigabit switching hub muse support IGMP and Jumbo Frame over 8K in order to achieve the best quality
4. If monitor shows green screen, please check if the switch running under gigabit and IGMP/Jumbo Frame function enabled.
5. If video not smooth please check if IGMP function enabled or bandwidth of switch closes to maximum.
6. If UTP and SFP connected together the first connected one will get the priority, the other one will online automatically once another one failed.
7. If Ethernet is not connected may cause unpredictable problem or OSD message error, please connect to the Ethernet and reboot.
8. Default EDID is 1080p 7.1 audio, you can use Menu function 44 to copy EDID from monitor of RX.
9. If the monitor of RX shows shortly then turns into black but OSD shows properly, please check the HDCP version of monitor support is tally with the source required, and the casting mode of TX/RX are the same and the HDCP setting is correct.
10. If receiver switches to transmitter which no video input, it will show blank screen or last still image for seconds.
11. Fast switch mode might cause screen or audio abnormal briefly when switch channel.
12. When output resolution is fixed, the screen or OSD might be cut a little if the source resolution is much different with the output (like 4K downscale to 720p).
13. In high resolution (like 1080p or 4K) the OSD response will be delayed a little bit.
14. In video wall mode, the OSD may not be in correct size and position
15. RS232 only support data transmission (TXD, RXD), not support hardware handshake (RTS, CTS, DTR, DSR…)
16. Power from power adapter with priority than power from PoE.
17. The front panel IR will be disable when external IR cable plugged.
18. If IR remote not work properly, please check the battery (especial in low temperature) and reset IR ID.
19. Audio in of RX only works at unicast mode, and the audio in and audio out of TX must be connected.
20. Audio in of RX is designed for mono Mic in, not for stereo Line in.
21. When using computer or mobile APP management the IP address should be set in same network segment.
22. TV wall setting parameter between APP/PC software and IR menu/Web are different and might be cover each other, we recommend set TV wall by one of two ways to prevent conflict.
23. PC software and APP operation please refer to software operating instruction.
24. Not recommend control by panel, computer software and APP at the same time to prevent conflict.
