1. I make a straight-through RJ-45 Jack to DB-9 Male connect. Item used: Port Server (RJ-45 Jack) RJ-45 straight-through cable (plug to plug) RJ-45 Jack / DB-9 Male connnector. This is how I made the connector: RJ-45 Plug DB-9 Male ------------ ------------ 1 n/a 2 blue 6 DSR 3 orange 7 RTS 4 black n/a 5 red 3 TxD 6 green 2 RxD 7 yellow 5 sGnd 8 brown 8 CTS 9 white 4 DTR 10 n/a This cable connects the digi port with the following devices/connector: Animatics motor/DB-9 female serial port. (Tx,Rx,RTS,CTS required) New Port ESP300 Motion Controller/Driver. (Tx,Rx,RTS,CTS required) 2. The ESP300 had alot of trouble with it serial communication. On 7/19/2002 it cabling was changed to: 10 pin 9-pin RJ-45 DB-9 1 No pin 2 N/C 3 RTS---------- 7 4 N/C 5 TxD---------- 3 6 Rxd---------- 2 7 SigGnd------- 5 8 CTS---------- 8 9 N/C 10 No pin This fixed the serial-port-kill-the-POM-controller problem. 3. The animatics motor only requires a 3 wire cable. This should work: 10 pin 9-pin RJ-45 DB-9 1 No pin 2 N/C 3 N/C 4 N/C 5 TxD---------- 3 6 Rxd---------- 2 7 SigGnd------- 5 8 N/C 9 N/C 10 No pin
