For all BrightSign units with RS232 Port
Any RS232 controller (requires external 5 volts for 
non-BrightSign)
8 Lighted Buttons (Lights Controlled)
 
 
    


RS232-8B-8L-MS
Features:
  - Box Size: 5-1/2L x 3-1/4W x 1.5H (inches)
 
  - Small footprint (3.0 x 3.0 inches)
 
  - No external power supply required if using a BrightSign for power.
 
  - 5V external 2.1mm jack if not BrightSign
 
  - Serial Setup: 38,400 baud, N,8,1 (standard RS232 communication)
 
  - Single byte controls all 8 switch lamps. Lights are on by default at 
  power-up.
 
  - RS232 Cable (not crossover cable)
 
  - Desk Mount or Wall Mount (same box)
 
 
Operation:
Operation:
  - 1. Activation of inputs 1-8 Sends out Ascii '1', '2', '3', '4', '5', 
  '6', '7' or '8' followed by <CR> (Carriage Return), because the BrightSign is 
  normally looking for 'Strings'.
    Note: Option1 Selects Binary or String as the output when a button is 
  pressed.  
  - 2. Send a single byte to control the output drivers (binary byte). See 
  the table below
 
Note: Rev 2.1 firmware (09/30/2014) update:
  - Allows for repeat of the same switch closure.  Prior firmware did not 
  report the same switch closure (multiple closures of the same switch).
 
  - When no switches are pressed (switches are released), a '0' (zero) is 
  reported.
 
  - Multiple switch closures reported.  I.E. Switch 1 is pressed (and 
  held), then switch 2 is pressed, switch 2 will be reported as a new switch 
  closure.
 
A single byte controls the Lights of the switches (buttons). To control the 
Lights, send a byte (use the 'serialsendbyte' command in BrightAuthor). The 
lamps will light according to the bit pattern of the 'Port Byte'.  I.E. Bit 
0 of the byte, will turn on Switch1 Light.
Example: To set the Lights, Send the byte that represents the bits of the 
output (see table below)
  - Bit     Binary              Decimal
 
  - 0       00000001b      1d        (Output1)
 
  - 1       00000010b      2d        (Output2)
 
  - 2       00000100b      4d        (Output3)
 
  - 3       00001000b      8d        (Output4)
 
  - 4       00010000b      16d      (Output5)
 
  - 5       00100000b      32d      (Output6)
 
  - 6       01000000b      64d      (Output7)
 
  - 7       10000000b      128d    (Output8)
 
Just add the decimal numbers together to get the bits set that you want.  
Setting all bits on (all lights on) is 255d (decimal).  Setting bits 0 and 
7 on is 128+1 or 129 decimal
  
    | Note: External Supply Voltage:  For 
	non-BrightSign use, contact HMS Electronics and order the RS232-8B-8L-5V.  
	We will add the 5 volt jack and the  hole for the external power connection. | 
  
Custom Overlays:  We can supply 2 color Custom Overlay 
(text and background are 2 colors):   Setup of $200 + $4 per overlay 
(less than 100).  This is very cost effective. You an get 10 custom 
overlays for $240.  Delivery about 2-3 weeks from date of order.
