6-2. Serial communications
ASTAT-IBP Plus is able to send and receive data through a serial RS232 port. Within this port ASTAT-IBP Plus communicates with a host PC.
For RS232 ASCII Communications, parameter "XP" must be set to 0.
6-2-1. RS232 port, wiring and communications settings
RS232 is an operating standard of communication only in terms of electrical characteristics (voltage, timing, etc.) while the
communication procedures are defined by ASCII.
The maximum allowed RS232 cable length is 3 meters. ASTAT-IBP Plus uses a connector with only 3 pins: TD, RD, SG.
