SK-ACPe
1. Voltages: Measure voltages at the gateway reader's terminal block, communications pins 1 to 5.
Connect the ground lead to pin 1 (logic ground) for all measurements.
a) Pin 2 (Receive Data, RXD). The voltage should read between -5 VDC to -12 VDC. This voltage comes
from the PC. If the voltage is wrong or missing, disconnect the reader from the PC, and measure the
voltages at the reader (should be 0.0 VDC) and at the PC (should be between -5 VDC to -12 VDC).
b) Pin 3 (Clear to Send, CTS). The voltage should read between +5 VDC to +12 VDC. This voltage comes
from the PC. If the voltage is wrong or missing, disconnect the reader from the PC, and measure the
voltages at the reader (should be 0.0 VDC) and at the PC (should be between +5 VDC to +12 VDC).
c) Pin 4 (Request to Send, RTS). The voltage should read between -5 VDC to -12 VDC. This voltage
comes from the Card Reader. If the voltage is wrong or missing, disconnect the reader from the PC,
and measure the voltages at the reader (should be -9.5 VDC) and at the PC (should be 0.0 VDC).
d) Pin 5 (Transmit Data, TXD). The voltage should read between -5 VDC to -12 VDC. This voltage
comes from the Card Reader. If the voltage is wrong or missing, disconnect the reader from the PC,
and measure the voltages at the reader (should be -9.5 VDC) and at the PC (should be 0.0 VDC).
After testing voltages, return to the Location/Properties/Connection box and re-check the box next to
"Gateway (RS-232)".
1.7 NET-CONV Converter Connection
If you cannot connect and you are connected using the NET-CONV converter, test voltages as follows:
1. Measure input voltage from the converter power supply. It should be between 9 VDC and 16 VDC.
2. Measure voltage between Ground (minus side of power supply) and TD (A). It should be 0 VDC.
3. Measure voltage between Ground (minus side of power supply) and TD (B). It should be between
2.5 VDC and 5 VDC.
If these voltages are incorrect, contact Secura Key Technical Support.
1.8 Power Reset
Occasionally it may become necessary to perform a power reset on a SK-ACPE panel (for example, after a
power surge.) The SK-ACPE has a multi-level power reset procedure, with options depending on how long
you hold down the reset button following restoration of power. The Unit will beep, indicating the level of reset
which has occurred.
To perform a Power Reset:
1. Disconnect power from the reader or panel (including any backup battery)
2. Hold down the reset button.
3. While holding the reset button, restore power, and continue holding the button until the unit beeps
and the desired reset level occurs:
One (1) beep will default the Baud rate to 38400 for the gateway (RS232), and (RS 485
communications), exit the printer mode, reset password to 12345, and resend the wireless
settings if being used.
Two (2) beeps (3 seconds later) will change the node ID's. This procedure will reset the node
address, requiring a recovery procedure in SK-NET™ (see below).
Three (3) beeps (15 seconds later) will perform a factory default for the panel.
