Voltage setting for the 4689 DBCS SurePOS Receipt Journal printer

To operate correctly with the SurePOS Models 721, 741, and 781, customers with

the 4689 DBCS SurePOS Receipt Journal printer must set the printer voltage to 24

V. All other RS-485 printers will work correctly with the SurePOS 700 at the default

setting of 38 V.

To configure the printer voltage to 24 V, you set the jumpers JP1 and JP2. Both

jumpers must have the same setting. Select pins 1-2 for 38 V (default) or pins 2–3

for 24 V. Figure 12 shows the location of the printer jumper.
