ePort Isolation Interface Adapter II Installation
Using Pulse Interface
ATTENTION
DO NOT REMOVE POWER FROM THE REPORT DEVICE DURING ANY TRANSACTION. REMOVING
POWER INCREASES THE POSSIBILITY OF NOT RECEIVING FUNDS FOR TRANSACTION
ACTIVITY. TO DISABLE OUR DEVICE WHILE IT’S CONNECTED TO YOUR MACHINE, YOU NEED
TO IMPLEMENT THE ENABLE LINES. ENABLE LINES ARE EXPLAINED BELOW.
ATTENTION
THIS DEVICE CAN NOT BE USED IN APPLICATIONS WITH VOLTAGES GREATER THAN 24
VOLTS DC.
REPORT POWER
The Red and Black wires are used to power the ePort Telemeter. Either a 24VAC,
2A or a 24VDC, 2A power supply is recommended.
COIN PULSE RELAY
The Orange, White, and Yellow wires are all part of the relay circuit. The
Isolation Interface Adapter eliminates the need for you to design your own
relay interface, by offering the flexibility of either a normally open or
normally closed set of contacts. These contacts are operated by the
Telemeter’s pulse output circuitry, and can control an external load of up to
2A at 24VDC. These settings are set up by a USAT Customer Service
Representative or by using USAlive.
ENABLE SIGNAL
The Brown and Purple wires are used to Enable or Disable card acceptance. This
circuit is designed to disable the ePort Telemeter from accepting cards while
in the middle of a vend session, or when a system error occurs. You may choose
not to use this feature if you intend on accepting cards during the vend
session (i.e. add time, top-off…).The user may disable the card reader during
a vend session by applying the Controller’s Enable output signal to these
wires. In an active low system, 0.0 VDC should be applied. In an active high
system, the voltage must be at least 90% of the maximum voltage of the system
(5VDC, 12VDC, 24VDC). Follow the table shown in the top right-hand corner of
this document to select the correct jumper (JP1, JP2, and JP3) for the voltage
level of the host system. The only valid voltage signal levels are 0.0 Volt
for the low signal level, and the selected system’s voltage level for the high
signal level.
CASH REPORTING: The Blue and Green wires are used to enable cash reporting (see diagram for connection). This feature is used by customers who want to monitor and report on their other payment devices such as Bill Accepter or Coin Mechanism. This input is configurable in the same way as the ENABLE SIGNAL and follows the same guidelines for voltage level as discussed in the ENABLE SIGNAL section. Follow the table shown in the top right-hand corner of this document to select the correct jumper (JP4, JP5, and JP6) for the voltage level of the host system.
