balanced cables, terminated at the Interchange iQ end in a pair of BNC connectors for 75
Ohm or an RJ45 connector for 120 Ohm.
Management Terminal Connection
When on-line control of InterChange iQ 2000 is required a permanent connection must be
established to the 9-way female D-type connector labelled
Management
, at the rear of the unit.
The maximum cable length is 30 metres (100 ft).
A terminal runs at 38400 baud, 8 data bits, 1 stop bit, no parity, with XON/XOFF flow control.
If a modem link is being used for the management terminal connection, connect the modem
to the management port using a straight through DTE-DCE cable, with a minimum of TX,
RX and Signal Ground pins connected. The modems must have XON/XOFF pass through
enabled.
