Title: Hardware Installation Guide.pdf
Each reader port supports a reader with TTL or RS-485 interface. Power to the reader is selectable: 12 VDC, or input voltage passed through (PT), 125mA maximum per reader port. This selection is made via jumper J2 and is made for both reader ports. For the selection of 12 VDC, the LNL-1320 must be powered by a 20 VDC minimum source. For readers requiring a different voltage or current capability, they must be powered separately.To fully utilize each reader port, a 6-conductor cable (18 AWG) is required when TTL signaling is used. RS- 485 signaling requires two 2-conductor cables. One cable for power (18 AWG) and one cable for communication (24 AWG). Reader port configuration is set via host software.revision 6 — 395LNL-1320 Dual Reader Interface ModuleTypical Reader WiringVORED (1)LED BZR D1/CLKBRN (4) ORG (5) WHT (3)0 12 3 4 5D0/DATGNDGRN (2)BLK (6)6 7 8 9 * #
