Data Formats

9.6.1

Stream Serial Data Format

If stream data transmission is configured for the COM and/or USBCOM port (
880 sends data using the Consolidated Controls serial data format shown in Figure 9-1:
<STX> <POL> <wwwwwww> <UNIT> <G/N> <S> <TERM>
ASCII 02
decimal
Polarity:
< space > = Positive
<–> = Negative
W eight: 7 digits, right-justified, dummy
zer o es, d ecimal point w ith no leadin g
zer oes except for leading zer o immediately
pr eceding the decimal point. Leading

Format can be changed, see Section 9.7.
Note
The character values can be changes for the stream format tokens, see Table 6-9 on page 62.
9.6.2

Print Output Serial Data Format

When print format is configured for the demand (print) port in the setup menus, the 880 uses a data string formatted
for a basic ticket printout. The particular ticket format printed depends on the indicator configuration. See
Section 7.0 for print formatting.
You can use the EDP commands, Revolution
variety of printers, and other remote equipment.
9.6.3 RS-485 Data Formats
The 880 has a built-in RS-485 software protocol which is enabled when you configure a port's TYPE as 485. On
the 880 only the COM port has hardware support for RS-485 communication.
All RS-485 communication with the 880 is via command and response. An external host must send a command
and wait for a response.
All remote commands are initiated using the data format shown in Figure 9-2:
<STX> <ADDRESS>
ASCII 02
decimal
