10.5 Data Formats
Continuous Output Serial Data Format
If continuous transmission is configured for a serial
port (STREAM parameter set to LFT or INDUST on
the SERIAL menu), the
920i sends data using the
Consolidated Controls serial data format shown in
Figure 10-2:

Figure 10-2. Continuous Output Serial Data Format
Demand Output Serial Data Format
When demand mode is configured for the serial port
(STREAM parameter set to OFF), the
920i uses a data
string formatted for a basic ticket printout. The
particular ticket format printed depends on the
indicator configuration.
You can customize the ticket to work with a wide
variety of printers, scoreboard displays, and other
remote equipment.
RS-485 Data Formats
Two-wire RS-485 communications is available on port
3 of the CPU board; four-wire RS-485 communications
is supported on the “A” ports of any installed serial
expansion cards.
The 920i has a built-in RS-485 software protocol which
is enabled when you assign a non-zero address to the
indicator. Valid RS-485 addresses must be in the range
1–255; the address is specified on the ADDRESS
parameter on the SERIAL menu.
All remote commands are initiated using the data
format shown in Figure 10-3:

If the initiating device address matches the port address
of an
920i on the RS-485 network, that indicator
responds. For example, with demand outputs, or in
response to a KPRINT command, the responding
indicator uses the format shown in Figure 10-4:

Figure 10-4. RS-485 Respond Data Format
Example: To send the KPRINT command from an
ASCII terminal to an indicator at address 65 (decimal)
on the RS-485 network, use the format shown in
Figure 10-3.
• The keyboard equivalent for the start-of-text
(
STX ) character is CONTROL-B .
• The indicator address (65) is represented by an
upper case “A”.
• The carriage return (CR) character is generated
by pressing the
ENTER key.
Therefore, to send the KPRINT command to the
indicator at address 65, enter the following at the
terminal:
CONTROL-B , A, K, P, R, I, N, T, ENTER .
The indicator responds with the format shown in
Figure 10-4:
