Troubleshooting
Communications problems between the reader and back-end host
These problems may be caused by incorrectly wiring the communications cable, using the wrong cable,
having a too-long cable run, or incorrectly setting communications parameters between host and reader.
Cable run for RS–232 exceeds 50 feet in length
Fifty feet exceeds the maximum length for RS–232 interface. The interface should be converted to
RS–422, wireless modem, fiber optic, or Wiegand.
Long RF cable runs to antennas
For the external antenna-series Encompass 4 Readers, long RF cable runs between the reader and
the antenna may cause signal degradation or loss. This scenario may be site-specific, but TransCore
recommends limiting antenna cable runs to less than 3dB of cable loss.
