Other Picture

The CentreCOM Micro Transceivers are 10Base-2 and 10Base-T compliant transceivers designed to reduce Ethernet cabling costs. Compact size allows these transceivers to connect directly to the workstation, bringing thin Ethernet or Unshielded Twisted Pair (UTP) wiring directly to the workstation. With UTP and inexpensive coax network media, distances up to 100 meters between workstations can be supported using UTP, and up to 185 meters using coax.The AT-MX20T, AT-210T and AT-210TS transceivers incorporate other functions that offer improved network reliability for workstations. The 10Base-T link integrity test function provides a continuous test of the connection to the multiport repeater. A test pulse is periodically transmitted and expected at the companion transceiver's receive side. If the pulse is not seen on the receive side, the transceiver is placed into link test fail mode. Normal operation of the transmit side is inhibited and the "Link" LED is turned off. Normal operation is resumed when the link is re-established by the reception of a valid packet or two valid link pulses. On all models Signal Quality Error (SQE)/Heartbeat test can easily be enabled or disabled via an externally accessible switch. The AT-210T and AT-210TS both have a single LED that indicates the status of the SQE test switch.
