Introduction
This document denes the electrical interface, serial data format, and communication protocols of the Serial
Communication Control Interface (SCOM). The purpose of this interface is to enable a computer application to control
one or more units. Unit refer to display product.
Serial / USB Interface Conguration
The serial / USB interface can have different congurations, selected by the OSD menu. The congurations is
dened as follows:
RS-232 One computer controls one unit, no individual address
USB One computer controls one unit, no individual address
4-wire RS-485/RS-422 One computer controls max 16 units, each with individual address.
2-wire RS-485 One computer controls max 16 units, each with individual address.
Each unit will be assigned with an address value before it is connected to a shared RS485/422 network. The user
application (PC) can send the message to the specic unit by marking the message with corresponding address
number. The unit which has the matching address will respond immediately, while the others keep silent.
Broadcast commands will be processed by all linked units simultaneously once the last byte of the message is
received. In order to avoid coniction on bus, each unit should respond back at different times. As the units are
working independently, they can hardly know how many units are linked in the same bus. In this case, the interval
between receiving message and responding back should be calculated in the base of their own address. The lowest
addressed unit will respond rst.
To calculate the address based interval, there is a formula to calculate the interval (Te):
Te = (Tr +Lr) * N, where
Lr = length of the ACK/NAK message response
Tr = Response time
N = the total number of monitors
Response time Tr is a xed value which are calculated to make sure there is no conict on the bus. Principally, Tr is
equivalent to 2.5 byte periods after the last byte of a command message is received. However, due to the difference
in microcontroller clock, all the units may not nish the message receive at the same timing point. So the Tr should be
calculated based on the jitter changes.
