Options Configuration 29
4.5 Option 5 – Expanded Serial Communications
The expanded serial communications options provide RS485 communications for the IQ 700. Option 5 features
include:
• Duplex communication for up to two weight indicators on a single serial port.
• RS485 half-duplex with U21 installed.
• RS485 full-duplex available with U21 and the KBT7116-13 kit installed.
• Direct keyboard access to the indicator address in normal operating mode.
• Poll/answer protocol.
• Unit address 1 - 98.
• Tag mode that adds the programmed address to standard serial output format.
• Stored ID mode allows an identification number to be held until written over by a new one.
• Counter sequentially counts on each valid print. Counts from 1 – 999,999.
TAG/LAN
Under option 5 there are two modes of serial operation that can be selected:
• TAG mode – Adds a two digit address to the standard serial format which “tags” printed data with the IQ
700’s address. This feature is useful when more than one indicator is set up on a site and serial data needs to
be identified with the indicator from which it was generated.
• LAN mode – Local Area Network can be configured as a two wire (half duplex) RS485 serial
communication by installing the driver chip into socket U21 or 5.2 LAN (full duplex) RS485/RS422 with
the additional installation of the KBT7116-13 kit.
Table 4-7. Option 5 Configuration
NOTE: Port 1 configuration (parameter 14) must be set for duplex, (du), demand mode (de), and the appropriate
baud rate. See Section 3.2 for wiring and serial protocol.
The option 5 configuration parameters are graphically illustrated in Figure 4-10, shown on the page 29.

5.2. Addr Allows selection of indicator address from
1 – 98). When either 5.2 or 5.5 is selected, the display
alternates between 5.2 Addr or 5.5 cnt, respectively
and its current numeric value. The alternation of the
display occurs until a new value is selected.
Addresses can be accessed in the normal
operating mode by pressing
