PROBLEM: CANNOT CONFIGURE
SYMPTOM:
CAUSE: Host serial cable.
SOLUTIONS:
1)Check cabling between host device and H- Series multiport. If the host device is a PC, you may check the cable using the TERM program. With TERM loaded on the appropriate com port, all handshaking lines should be high (except possibly DCD which is not used). If the CTS or DSR lines are not high, compare the pinout of your cable with the pinout shown in Figure 1 on Page 10. If lines are high, power down the multiport. You should notice the CTS and DSR lines go low. If they do not, there is a good chance the cable is not correct.
2)Check the installation procedures for host computer's serial port. COM1 must generate an interrupt on IRQ4 (COM2 on IRQ3). Also, check any jumpers for defining port configuration which should be jumpered for DTE, not DCE.
