MERIT LI-LIN FASTDOME PROTOCOL FOR MAIN CABINET AND RECEIVER

1. Description: The receiver and cabinet communicates by standard RS-485 interface.

UART Format: None parity bit, 8 data bits, 1 stop bit, baud rate: 9600 bps

Main cabinet in active mode, whereas receiver in passive mode.

2. From the system after - reset. Main cabinet will send out 3 byte to receiver then receiver response 3 bytes right away.

Note 1. For error - correction consideration such as code missing. As receiver get the first code then it must calculate how much time to get other two. definitely in 2.5 ms. On the other hand , receiver response 3 codes in 4 ms.

Note 2. NO-KEY command - To stop (Pan Right /Pan Left / Tilt Up / Tilt Down / Focus Far / Focus Near / Zoom In / Zoom Out / Iris Large / Iris Small ) movement enter OFFh for 3rd byte.

Example: Bytel=ID address, Byte2=00h, Byte3=0FFh

Note 3. To start AUTO PAN status, 3rd byte in the TYPE A command must be entered as OAh. Please refer to page 2.

Note 4. There are 2 ways to stop AUTO PAN status.

a. 3rd byte in the TYPE A command must be entered as OAh. Please refer to page 2.

b. 3rd byte in the TYPE D command must be entered as 0D2h. Please refer to page 3.

Note 1: When a relay on ( non toggle status ) code received, the corresponding relay is triggered on immediately. As soon as the receiver does not continue to receive the same code, relay will be turned off after 500ms delay. To turn off immediately, NO-KEY command sent.

Note 2: To activate or stop AUTO PANfunction : When first 0Ah command sent, receiver will active AUTO PAN function. Receiver will send auto pan ON status response back to system immediately. When 2nd 0Ah

command sent, receiver will stop AUTO PAN function. And receiver will send auto pan OFF status response

back to system immediately. Note 3: For 07h command in speed dome configuration is for FLIP function. 07h command in receiver

configuration is for AUX2 input. Note 4: For PIH-7625 series speed dome, 06h command is to activate on screen display setup menu. 03h command

is to exit on screen display setup menu. Note 5: For PIH-7625 series speed dome, enter 05h command once to activate the manual focus, zoom and iris

speed in the OSD SET-UP MENU. Enter 05h command again to exit and return to factory default speeds. Note 6: For PIH-7625 series speed dome, Increment hotkey to control IR filter function change. Enter 04h

command 1st time then IR filter will be On. Enter the same code 2nd time IR filter will be Off. Enter the 3rd

time IR filter will be Auto.
