2.10 Serial Port Wiring
The IQ 700 serial port can be configured to communicate directly to a printer, remote display, or other device using
20 mA active/passive, RS-232, or RS-485.
Access to this serial communication port is through the water seal cap (TB2 and TB4) located on the back of the IQ
700 indicator (see Figure 2-9). Wiring is extended through this connector and wired inside the indicator. See the
output connector diagram in Figure 2-10 for connector and wire identification. Select the appropriate terminals and
set switch S1 accordingly.
