A.6 M24SII-V07 MODULE: EIA-422/EIA-232
PROTOCOL SELECTION AND EXTERNAL POWER
You may configure individual ports on the M24SII-V07 module to communicate with either EIA-422 (default) or EIA-232 protocol. Protocol selection is accomplished via jumper setting. You may also enable external power for individual ports to supply power to the Tran- x SP-01 or SP-02 via jumper setting. If you need to reconfigure any of the ports on this module type, please use the following instructions.
1.IMPORTANT: If the M24SII-V07 module is installed in the Model 24SII chassis, remove power from the Model 24SII by positioning the on/off switch to the OFF position and unplugging the power cord. Remove the module by unscrewing the two straight slot screws securing it to the back panel and pulling the module out.
2.Refer to Appendix D.8 and locate the four nine-position jumper locations for protocol selection and the four three-position jumper locations for external power. The jumper locations are marked on the solder side of the connector board for protocol selection and external power respectively as JP1 and JP5 for Port 1, JP2 and JP6 for Port 2, JP3 and JP7 for Port 3, and JP4 and JP8 for Port 4.
3.Each port is configurable for EIA-422 or EIA-232 protocol by installing a six-positon jumper to either the 422 or 232 position as marked on the connector board. The center row of holes for each port will be occupied by three of the pins on the jumper and the row of holes for either EIA-422 or EIA-232 will be occupied by the other three pins of this jumper.
4.External power is enabled for each port by installing a two- position jumper to the +12 position (as marked on the connector board) and the center position of the jumper location.
