DX-LAN Status
The DX-LAN driver monitors several types of errors that may occur on
the network. The detector reads the DX-LAN error counts and displays
them on this screen, along with the DX-LAN addresses. Most errors are
caused by a defective cable, missing cable, or incorrectly terminated
cable. The DX-LAN cable must be RG58U or RG58AU.

Description
Displays the three-byte DX-LAN ID programmed into the detector
Moduleware (in HEX). The ID is unique to the detector and never
changes.
Displays the six-byte DX-LAN address assigned by the PC (in
HEX). The first three bytes are the system assignment; the last three
bytes are the assignment within the system.
Indicates that 16 unsuccessful transmissions of the same packet
occurred, due to collisions.
Indicates that a ready response could not be issued within
2.4 microseconds after the WR signal was asserted. This occurs
when the transmit buffer memory is full.
Indicates that data from the transmit section of the hardware buffer
memory is not available for serial transmission. The DX-LAN will
continue to send out this data frame.
Indicates that a packet was received with an alignment error,
meaning that there were one to seven extra bits at the end of the
packet. This is usually caused by a collision or a faulty transceiver.
