DESCRIPTION
4 LAN LEDs

LNK – Indicates when there is a connection to the rear panel LAN
port.
ACT – Indicates communication (activity) at the rear panel LAN port.
5 RESET BUTTONS
HW-R - Initiates system hardware reset.
SR-R - Pressing this in combination with HW-R button performs a
system restart without loading the program. Pressing it alone while
the system is running restarts the program.

From MP2 or MP2E
(TXD-) RS-422 Transmit Data (Idles low)
* RS-422 transmit and receive are balanced signals requiring two lines plus
a ground in each direction. RXD+ and TXD+ should idle high (going low at
start of data transmission). RXD- and TXD- should idle low (going high at
start of data transmission). If necessary, RXD+/RXD- and TXD+/TXD-
may be swapped to maintain correct signal levels.
