Page 197 C.1.8.1 Keyboard and Mouse Port The keyboard and mouse are connected to an 8-pin DIN connector, located on the motherboard, and to two serial ports on the SuperIO component. Each serial port on the SuperIO ASIC provides 16-byte FIFO buffering. Data is asynchronously exchanged with the keyboard and mouse at 1200 baud.

Receivers also operate at nominal 5-Vdc TTL levels and can withstand peak voltage transients between -2 Vdc and 7 Vdc without damage or improper operation. The high-level threshold is less than or equal to 2.0 Vdc and the low-level threshold is at least 0.8 Vdc.
Page 200 -6 V and +6 Vdc. Switching from RS-232 to RS-423 protocol is accomplished by changing jumpers J2604 and J2605. Jumper positions 1 and 2 are for RS-232 and jumper positions 2 and 3 are for RS-423. Sun Ultra 60 Service Manual ♦ March 1999, Revision A C-20...
Page 201: Ethernet
The preferred signaling protocol is RS-423. The higher voltages of R-232 make it difﬁcult to switch at the higher baud rates. The maximum rate for RS-232 is approximately 64 Kbaud while the maximum rate for RS-423 is 460.8 Kbaud. The system default is set to RS-232.
Page 202 The Ethernet port supports automatic negotiation. At power up, an on-board transceiver advertises 100BASE-TX in half-duplex mode, which is conﬁgured by the automatic negotiation to the highest common denominator based on the linked partner.
