5.6.62 MAC00-FC2 - How to connect the RS232 interface
This has to be done if MacTalk is used in the CAN-Open configuration.
The illustration below shows how to connect the MAC00-FC2 directly to a PC COM
port. The drawing is based on standard cables from JVL, type WG0402, WG0410 or
WG0420. See also
Accessories, page 448 for a complete list of cables and connectors.
If the MAC motor is connected to the same RS232 line as other motors, the terminal TX-
PD should only be connected at one of the motors.
If one of JVL’s standard RS232 cables (RS232-9-1 or -n) is used between the DSUB con-
nector shown and the PC com port, the RX and TX pins must be swapped since they
cross in these standard cables.
