8.10.3 T2000-A450X Link Options
There are 2 groups of links on the underside of the T2000-A4500 PCB, the receive
(R) group and the transmit (T) group. Each group contains 6 bits that are pulled
logic high or low, by either solder links or zero ohm resistors.
The receive settings are set by links R-0 to R-5 and the transmit settings by links T-
0 to T-5. A short to the 5V line represents a '1', and a short to ground represents a
'0'.
The following diagram shows the T2000-A450X PCB, with links indicated.
