OVERVIEW
The BrightSign HD120, HD220, and HD1020 players can be used to drive a variety of HDTV and computer monitors for
digital sign and kiosk applications. In addition to driving a video display, these players have many different built-in
interfaces that allow them to be controlled.
This reference manual specifies the hardware interfaces on the BrightSign HD120, HD220, and HD1020. This manual
does not describe any software functions.

Power Connector
The power connector on this board is rated for 5 V at 3 A. The plug for the connector is a standard, center-positive 5.5mm
plug with a 1.65mm center pin hole.
DE9 RS-232 Connector
The RS-232 connector is a male DE9. Like PCs, the BrightSign HD series of players are DTE devices. The input to the
chip accepts a range between +30V and -30V, so it is compatible with standard +12V and -12V signaling. The output from
the chip is rated at a typical +7V and -7V, which exceeds the voltage required by the RS-232 specification.
The baud rate is 115,200, with no parity, 8 data bits, and 1 stop bit. There is no hardware or software flow control. The
maximum cable length is 50 meters, and the total cable capacitance is 2500pF.
Note: A lower capacitance cable allows you to use cable lengths beyond 50 meters.
The following diagram illustrates the behavior of the TX and RX signal:
The following table illustrates the pinout of the DE9 on the HD series of players:

DA15 Switch/LED Connector
The switch/led connector is a DA15 female. This connector is used to allow the player to control external LEDs or other
devices requiring 24 mA of current or less.
Connect the LED outputs to the LED ANODE and connect the LED CATHODE to the ground. If you want to connect
another device, then the output is capable of sourcing or sinking up to 3.3 V at 24 mA, but there is a series resistor of 100
Ohms in each line.
The connector also allows the connecting of external contact closures to the ground. In order to connect a switch, connect
one side of the switch to the switch input, and connect the other side to one of the ground pins on the DA15 connector.
The connector can also supply 3.3 V at up to 500 mA to an external device. The 3.3 V output is polyfuse-protected and
can source up to 500 mA.
If one BrightSign player is driving the inputs on another BrightSign player, then you can drive at most three inputs from
one output. The following calculations explain this limitation:
Note: The GPIO outputs have 100 Ohm series resistors; the GPIO inputs have 1K pullup resistors to 3.3 V; and the input
threshold on the 541 chips is 2 V high and .8 V low. The high voltage is not a problem, but the low voltage can be if there
are too many inputs connected to one output.

1 out driving 1 in V=3.3*100/(100+1,000)=0.3
1 out driving 2 in V=3.3*100/(100+500)=0.55
1 out driving 3 in V=3.3*100/(100+333.3)=0.76
1 out driving 4 in V=3.3*100/(100+250)=.94 (This is too high, so 1 output
driving 3 inputs is the maximum)
The following table illustrates the pinout of the DA15 on the HD series of players:

A button/LED/IR board can be used to demonstrate the GPIO and IR functions on a BrightSign player. This board is built
by a third-party manufacturer and can be purchased upon request.
