C-NET (98) P2-T, C-NET (98) P2-5T, C-NET (98) P2-52T (CONTEC) PnP compatible C bus NIC (LAN board).C-NET (98) P2-T has 10BASE-T connector, C-NET (98) P2-5T is 10BASE-5 / T connector, C-NET (98) P2-52T is 10BASE-T / 5/2 Each connector is equipped.It is not compatible with Windows 95 compatible with EPSON. In C-NET (98) P2-52T, there is one 3 jumper switch on the board. ・ Three jumper switches (C-NET (98) P2-52T only): 10BASE-5 / 2 switching (Auto / Fixed) setting  Two shorts on AUI side ■ MAU and external transceiver connected to 10BASE-5 12V           10BASE-5 / 2 switching circuit operates normally when not consuming           do not do.Set in this case.  2 shorts on AUTO side ■ Default setting.Usually, use as it is. This jumper switch is used because 10BASE-T connection is prioritized when 10BASE-T is used The setting in is invalid. I / O port address: n3D0h to n3DFh (n = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 9                  A, B, C, D, factory setting: n = 0)           16 bytes occupied (automatically or by software) Interrupt level: Use one of INT 0, 1, 2, 3, 4, 5, 6 (automatic or Set by software, factory setting: INT 0) power consumption  10BASE-5: +5 V = 70 mA, +12 V = 500 mA  10BASE-2: +5 V = 350 mA  10BASE-T: +5 V = 80 mA Operating temperature range: 0 to 50 °, operating humidity range: 20 to 80% (no condensation) LED indicator (LED operation is valid only when using 10BASE-T)  DUP / COL: On ■ Whether the duplex mode setting is full duplex,          Half-duplex configuration causes collisions          Indicates that it is occurring.  RX: On ■ Indicates that data is being received.  TX: ON: Indicates that data is being transmitted.  LINK: On ■ Data link is good and a twisted pair cable is connected To indicate that     Unlit ■ Connection failure of twisted pair cable or using 10BASE-5 / 2 To indicate that
