Refer to Figure 1-3. RS-232 data signals are defined as either Mark or Space, while
control signals are ON (Active-Positive Voltage) or OFF (Inactive-Negative Voltage).
Although the permitted voltage levels can range from ±3VDC to ±25VDC, the levels for
the Z4M/Z6M printer are as follows:
RS-232 Transmit and Receive Data
Mark or OFF = -7 to -10 VDC Space or ON = +7 to +10 VDC
Refer to Figure 1-4. RS-422 and RS-485 data signals are also either Mark or Space. The
voltage levels are +5 VDC and 0 VDC when monitored from a specified reference point.
The levels for the Z4M and Z6M printer, when referenced to signal ground are:
RS-422 and RS-485 Transmit and Receive Data
Mark Output/Input A = +5V and Output/Input B = 0VSpace Output/Input A = 0V
and Output/Input B = +5V
