2SP-550 Configuration

Serial Configuration

Parallel Configuration

1. Determine the number of serial ports installed in your system. Each serial

port will have an unique "COM" designation.Configure the ports of the 2SP-

550 for two unused COM addresses.

2. Determine which IRQ's (interrupts) are free in your system. Configure each

serial port on the 2SP-550 for an unused IRQ. Although some devices allow

sharing of IRQ's, this is not recommended.

3a. For Serial 1, install the jumper above the number corresponding to the

desired IRQ, so that it covers the pin in the bottom row and the pin in the

middle row.

3b. For Serial 2, install the jumper above the number corresponding to the

desired IRQ, so that it covers the pin in the top row and the pin in the middle

row.

1. Determine the number of parallel ports installed in your system. Each parallel

port will have an unique "LPT" designation. Configure the port of the 2SP-

550 for an unused LPT address (e.g. If you have a parallel port installed as LPT

1 using hexidecimal address 0378, configure the 2SP-550 as LPT 2 using

address 0278h).

2a. Configure the parallel port for an unique IRQ, if required. Many applications

do not require an IRQ assignment for operation.Consult the documentation

accompanying your software and/or operating system.

2b. Typically, a parallel port configured for LPT 1 at address 0378h,will be set for

IRQ 7 and a port configured for LPT 2 at address 0278h, will be set for IRQ 5.

3. The 2SP-550 supports two parallel modes: Output (SPP, 4-bit, "nibble") & Bi-

directional (8-bit, "byte," PS/2 compatible).

Do not install more than one IRQ jumper per serial port.

Note: To disable a port, remove the jumper from both of the IRQ and

the corresponding COM or LPT jumper configuration pins.
