10.3 Data Formats
10.3.1 Continuous Output Serial Data Format
If continuous transmission is configured for the EDP
or printer port (STREAM parameter on the SERIAL
m e n u ) , t h e I Q p l u s 7 1 0 s e n d s d a t a u s i n g t h e
Consolidated Controls serial data format shown in
Figure 10-1:
Figure 10-1. Continuous Output Serial Data Format
10.3.2 Demand Output Serial Data Format
When demand mode is configured for the EDP or
printer port in the setup menus (PRNDEST on the
SERIAL menu), the IQ plus 710 uses a data string
formatted for a basic ticket printout. The particular
ticket format printed depends on the indicator
configuration.
Yo u ca n us e t h e E DP p o rt o r key p ad t o f u l l y
customize the ticket to work with a wide variety of
printers, scoreboard displays, and other remote
equipment. See Section 6.0 on page 45 for more
information on custom print formats.
10.3.3 RS-485 Data Formats
The IQ plus 710 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 10-2:
Figure 10-2. RS-485 Send Data Format
If the initiating device address matches the port
address of an IQ plus 710 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 10-3:
Figure 10-3. 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 10-2.
• The keyboard equivalent for the start-of-text
(
S T X
) c h a r a c t e r i s
C O N T R O L - B
( s e e
Table 10-3 on page 65).
• 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 10-3:

If continuous transmission is configured for the EDP
port (STREAM parameter on the SERIAL menu), the
IQ plus 710 sends data using the data format shown in
Figure 10-4:
