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:

Figure 10-3. RS-485 Send Data Format

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:

<STX> A

If continuous transmission is configured for the serial
port, the

920i

sends data using the data format shown in
