uPASS Target | installation guide
13/
3 Connections
The uPASS Target has 7 connectors at the bottom of the device (see Figure 6).
CONN. 2, CONN. 3 and CONN. 5 are shielded connectors.
All connectors shown in this chapter are seen from the outside.
All connectors for the cables are supplied (except mini USB and TNC (Ext. Ant.)).
The connections aren’t secured and the communication maybe unencrypted. If safety is paramount it is recommended
to place the connectors and cables so they cannot be accessed outside the security zone.

Figure 7 shows a simplified schematic overview for most of the uPASS Target connections. This figure shows the
overview when the reader is in normal UHF mode (not TRANSIT compatible) determined by SW1-1 (see chapter 4).
3 Points (A, B and C) control the direction of the serial interface to USB, RS422, RS485 or one Ethernet channel (the
other is fixed to the UHF processor):
A. When the USB cable is connected, the USB interface is used
B. The “main comm. interface” setting (see chapter 6.5.1) determines the use of Ethernet or RS422/RS485
C. Determined by SW1-2 (located near the USB port) RS422 or RS485 is used
