Hello, i am attempting to build a serial cable so i can use an old mac laptop [powerbook510] to boot a sun sparc ipc and start it network booting. Google reveals the following pinouts:
AppleMac [1] DIN8 Signal Description Pin ---------------------------------- 1 RTS Handshake output 2 CTS Handshake input 3 TXD- Transmit data (inverted) 4 SG GND 5 RXD- Receive data (inverted) 6 TXD+ Transmit data 7 DCD General Purpose Input 8 RXD+ Receive data Sparc IPC [2] DIN8 Signal Description Pin ---------------------------------- 1 DTR Data Terminal Ready 2 CTS Clear to Send 3 TXD Transmit Data 4 GND Ground 5 RXD Receive Data 6 RTS Request to Send 7 DCD Data Carrier Detect 8 RTXC Receive Clock My first question is: how do i wire it? do i try and match the pins up ie RTS-->RTS or do i cross over as in RTS-->CTS? Next question, whats with TXD[+-] on the mac but only TXD on the sparc? can i just use TXD+ -->TXD? [or TXD+ -->RXD if crossed over] then ignore TXD-? The weak debian link is that it will [if i ever get it booted] be a debian box :-) thanks, hugh Datafrom: [1]http://62.194.125.41:8080/pinouts/mac_pc_serial.html [2]http://www.stokely.com/unix.serial.port.resources/A-B-Ycablepinout.html#ipc.ipx.link -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
